ure at which the entropies of perfect crystals vanish or the temperature at which the entropy change of an adiabatic process vanishes a state of absolute zero was first proposed by guillaume amontons in one seven zero two who was investigating the relationship between pressure and temperature in gases he lacked accurate and precise thermometers so his results were only semi quantitative but he established that the pressure of a gas increases by roughly one third between cold temperatures and the boiling point of water his work led him to speculate that a sufficient reduction in temperature would lead to the disappearance of pressure the problem is that all real gases liquefy during the approach to absolute zero in one eight four eight william thomson one st baron kelvin proposed an absolute thermodynamic temperature scale in which equal reduction in measured temperature gave rise to equal reduction in the heat of a body this freed the concept from the constraints of the gas laws and established absolute zero
as the temperature at which no further heat could be removed from a body absolute zero has never been reached and it appears it never will be it may be asymptotically approached like the speed of light but never attained kinetic theory and motion according to kinetic theory there should be no movement of individual molecules at absolute zero so any material at this temperature would be solid in a monatomic gas most of the energy is in the form of translational motion and the temperature can be measured in terms of the distribution of this motion with slower speeds corresponding to lower temperatures perhaps even down to absolute zero but this is contrary to experimental evidence and it is predicted that helium will never solidify no matter how much it is cooled or compressed because of quantum mechanical effects the speed at absolute zero is larger than zero and depends along with the energy on the volume within which a particle is confined at absolute zero the molecules and atoms in a system are all in their
ground state the state of lowest possible energy and a system has the least amount of kinetic energy allowed by the laws of physics but the lowest possible zero point energy for a confined particle in a box is not zero rather than being fixed and non moving the equation for the energy levels shows that no matter how low the temperature gets even when the quantum number takes its minimum value of one a particle still has some translational kinetic energy and motion this is a reflection of heisenberg s uncertainty principle which states that the position and the momentum of a particle cannot both be known precisely at any given time similarly using the harmonic approximation for the vibrations of a diatomic molecule the quantum harmonic oscillator yields a positive zero point energy even when the vibrational quantum number takes its minimum value of zero for polyatomic molecules and for bodies such as crystals whose normal mode motions can not be assigned to individual atoms or chemical bonds the lowest energy

adiabatic processes in thermodynamics for adiabatic processes in quantum mechanics see adiabatic process quantum mechanics for atmospheric adiabatic processes see adiabatic lapse rate in thermodynamics an adiabatic process is a process in which no heat is transferred to or from working fluid the term adiabatic literally means an absence of heat transfer for example an adiabatic boundary is a boundary that is impermeable to heat transfer and the system is said to be adiabatically or thermally insulated an insulated wall approximates an adiabatic boundary another example is the adiabatic flame temperature which is the temperature that would be achieved by a flame in the absence of heat loss to the surroundings an adiabatic process which is also reversible is called an isentropic process the opposite extreme in which the maximum heat transfer with its surroundings occurs causing the temperature to remain constant is known as an isothermal process since temperature is thermodynamically conjugate to entropy the is
othermal process is conjugate to the adiabatic process for reversible transformations a transformation of a thermodynamic system can be considered adiabatic when it is quick enough so that no significant heat transfer happens between the system and the outside at the opposite a transformation of a thermodynamic system can be considered isothermal if it is slow enough so that the system s temperature can be maintained by heat exchange with the outside adiabatic heating and cooling adiabatic heating and cooling are processes that commonly occur due to a change in the pressure of a gas adiabatic heating occurs when the pressure of a gas is increased an example of this is what goes on in a bicycle pump after using a bicycle pump to inflate a pneumatic tyre or soccer ball the barrel of the pump is found to have heated up as a result of adiabatic heating a common motorized air compressor operating at pressures up to one five zero psi can reach outlet temperatures of several hundred degrees fahrenheit adiabatic cool
ing occurs when the pressure of a gas is decreased such as when it expands into a larger volume an example of this is when the air is released from a pneumatic tire the outlet air will be noticably cooler than the tire and after all the air has escaped the valve stem will be cold to the touch diesel engines rely on adiabatic heating during their compression stroke to reach the high temperatures needed to ignite the fuel such temperature changes can be quantified using the ideal gas law adiabatic cooling does not have to involve a fluid one technique used to reach very low temperatures thousandths and even millionths of a degree above absolute zero is adiabatic demagnetisation where the change in magnetic field on a magnetic material is used to provide adiabatic cooling ideal gas for a simple substance during an adiabatic process in which the volume increases the internal energy of the working substance must necessarily decrease the mathematical equation for an ideal fluid undergoing an adiabatic process is p

imitive culture he used it to mean a belief in spirits i e mystical supernatural non empirical or imagined entities tylor s use of the term has since been widely criticized see details below today the term is used with more respect today animists live in significant numbers in countries such as zambia the democratic republic of the congo gabon the republic of guinea bissau indonesia laos myanmar papua new guinea the philippines russia sweden thailand and the united states of america modern neopagans especially eco pagans sometimes describe themselves as animists meaning that they respect the diverse community of living beings with whom humans share the world cosmos some however use the term to refer to the idea that the mother goddess and horned god consist of everything that exists this pantheism in which god is equated with existence is different from animism because it imputes value to individual living beings and or objects because they might reveal a larger reality or divinity behind everything animists
respect beings for their own sake whether because they have or are souls as in the original definition of the word or because they are persons the new definition overview in some animistic worldviews found in hunter gatherer cultures the human being is often regarded as on a roughly equal footing with animals plants and natural forces therefore it is morally imperative to treat these agents with respect in this worldview humans are considered a denizen or part of nature rather than superior to or separate from it in such societies ritual is considered essential for survival as it wins the favor of the spirits of one s source of food shelter and fertility and wards off malevolent spirits in more elaborate animistic religions such as shinto there is a greater sense of a special character to humans that sets them apart from the general run of animals and objects while retaining the necessity of ritual to ensure good luck favorable harvests and so on most animistic belief systems hold that the spirit survives phy
sical death in some systems the spirit is believed to pass to an easier world of abundant game or ever ripe crops while in other systems e g the navajo religion the spirit remains on earth as a ghost often malignant still other systems combine these two beliefs holding that the soul must journey to the spirit world without becoming lost and thus wandering as a ghost funeral mourning rituals and ancestor worship performed by those surviving the deceased are often considered necessary for the successful completion of this journey rituals in animistic cultures are often performed by shamans or priests who are usually seen as possessing spiritual powers greater than or external to the normal human experience the practice of head shrinking as found among headhunters derives from an animistic belief that one s war enemies if the spirit is not trapped within the head can escape the body after the spirit transmigrates to another body they take the form of a predatory animal and exact revenge animism is the belief tha
t objects and ideas including animals tools and natural phenomena have or are expressions of living spirits origins early ideas on the subject of the soul and at the same time the origin of them can be illustrated by analysis of the terms applied to them readers of dante know the idea that the dead have no shadows this was no invention of the poet s but a piece of traditional lore among the basutus it is held that a man walking by the brink of a river may lose his life if his shadow falls on the water for a crocodile may seize it and draw him in in tasmania north and south america and classical europe is found the conception that the soul umbra is identical with the shadow of a person more familiar to europeans is the connection between the soul and the breath this identification is found both in indo european and semitic languages in latin we have spiritus in greek pneuma in hebrew ruach the idea is found extending other planes of culture in australia america and asia for some of the native americans and fir
st nations the roman custom of receiving the breath of a dying man was no mere pious duty but a means of ensuring that his soul was transferred to a new body other familiar conceptions identify the soul with the liver see omen or the heart with the reflected figure seen in the pupil of the eye and with the blood although the soul is often distinguished from the vital principle there are many cases in which a state of unconsciousness is explained as due to the absence of the soul in south australia wilyamarraba without soul is the word used for insensible so too the autohypnotic trance of the magician or shaman is regarded as due to their visit to distant regions or the netherworld of which they bring back an account telepathy or clairvoyance with or without trance may have operated to produce a conviction of the dual nature of man for it seems possible that facts unknown to the automatist are sometimes discovered by means of crystal gazing sickness is often explained as due to the absence of the soul and mean
s are sometimes taken to lure back the wandering soul in chinese tradition when a person is at the point of death and their soul believed to have left their body the patient s coat is held up on a long bamboo pole while a priest endeavours to bring the departed spirit back into the coat by means of incantations if the bamboo begins to turn round in the hands of the relative who is deputed to hold it it is regarded as a sign that the soul of the moribund has returned see automatism more important perhaps than all these phenomena because more regular and normal was the daily period of sleep with its frequent fitful and incoherent ideas and images the mere immobility of the body was sufficient to show that its state was not identical with that of waking when in addition the sleeper awoke to give an account of visits to distant lands from which as modern psychical investigations suggest they may even have brought back veridical details the conclusion must have been irresistible that in sleep something journeyed f
orth which was not the body see astral travel in a minor degree revival of memory during sleep and similar phenomena of the sub conscious life may have contributed to the same result dreams are sometimes explained in animist cultures as journeys performed by the sleeper sometimes as visits paid by other persons by animals or objects to the sleeper hallucinations possibly more frequent in the lower stages of culture must have contributed to fortify this interpretation and the animistic theory in general seeing the phantasmic figures of friends at the moment when they were whether at the point of death or in good health many miles distant must have led people irresistibly to the dualistic theory but hallucinatory figures both in dreams and waking life are not necessarily those of the living from the reappearance of dead friends or enemies primitive man was inevitably led to the belief that there existed an incorporeal part of man which survived the dissolution of the body the soul was conceived to be a facsimil
e of the body sometimes no less material sometimes more subtle but yet material sometimes altogether impalpable and intangible if the phenomena of dreams were as suggested above of great importance for the development of animism the belief which must originally have been a doctrine of human psychology cannot have failed to expand speedily into a general philosophy of nature not only human beings but animals and objects are seen in dreams and the conclusion would be that they too have souls the same conclusion may have been reached by another line of argument folk psychology posited a spirit in a person to account amongst other things for their actions a natural explanation of the changes in the external world would be that they are due to the operations and volitions of spirits but apart from considerations of this sort it is probable that animals must have been regarded as possessing souls early in the history of animistic beliefs we may assume that man attributed a soul to the beasts of the field almost as
soon as he claimed one for himself the animist may attribute to animals the same sorts of ideas the same soul the same mental processes as himself which may also be associated with greater power cunning or magical abilities dead animals are sometimes credited with a knowledge of how their remains are treated potentially with the power to take vengeance on the hunter if he is disrespectful it is not surprising to find that many peoples respect and even worship animals see totem or animal worship often regarding them as relatives it is clear that widespread respect was paid to animals as the abode of dead ancestors and much of the cults to dangerous animals is traceable to this principle though we need not attribute an animistic origin to it with the rise of species deities and the cult of individual animals the path towards anthropomorphization and polytheism is opened and the respect paid to animals tended to be reduced or lost entirely especially in its strict animistic character plant souls just as human so
uls are assigned to animals so too are trees and plants often credited with souls both human and animal in form all over the world agricultural peoples practise elaborate ceremonies explicable as wilhelm mannhardt has shown on animistic principles in europe the corn spirit sometimes immanent in the crop sometimes a presiding deity whose life does not depend on that of the growing corn is conceived in some districts in the form of an ox hare or cock in others as an old man or woman in the east indies and americas the rice or maize mother is a corresponding figure in classical europe and the east we have in ceres and demeter adonis and dionysus and other deities vegetation gods whose origin we can readily trace back to the rustic corn spirit forest trees no less than cereals may have their indwelling spirits the fauns and satyrs of classical literature were goat footed in russia the tree spirit of the russian peasantry takes the form of a goat in bengal and the east indies woodcutters endeavour to propitiate th
e spirit of the tree which they cut down in many parts of the world trees are regarded as the abode of the spirits of the dead just as a process of syncretism has given rise to cults of animal gods tree spirits tend to become detached from the trees which are thenceforward only their abodes here again animism has begun to pass into polytheism object souls some cultures do not make a distinction between animate and inanimate objects natural phenomenon geographic features everyday objects and manufactured articles may also be attributed with souls in the north of europe in ancient greece in china the water or river spirit is horse or bull shaped the water monster in serpent shape is even more widely found but it is less strictly the spirit of the water the spirit of syncretism manifests itself in this department of animism too turning the immanent spirit into the presiding djinn or local god of later times animism and death in many parts of the world it is held that the human body is the seat of more than one s
oul on the island of nias four are distinguished the shadow and the intelligence which die with the body a tutelary spirit termed begoe and a second spirit which is carried on the head similar ideas are found among the euahlayi of southeast australia the dakotas and many other tribes just as in europe the ghost of a dead person is held to haunt the churchyard or the place of death so do other cultures assign different abodes to the multiple souls with which they credit man of the four souls of a dakota one is held to stay with the corpse another in the village a third goes into the air while the fourth goes to the land of souls where its lot may depend on its rank in this life its sex mode of death or sepulture on the due observance of funeral ritual or many other points from the belief in the survival of the dead arose the practice of offering food lighting fires etc at the grave at first maybe as an act of friendship or filial piety later as an act of ancestor worship the simple offering of food or shedding
of blood at the grave develops into an elaborate system of sacrifice even where ancestor worship is not found the desire to provide the dead with comforts in the future life may lead to the sacrifice of wives slaves animals and so on to the breaking or burning of objects at the grave or to the provision of the ferryman s toll a coin put in the mouth of the corpse to pay the traveling expenses of the soul but all is not finished with the passage of the soul to the land of the dead the soul may return to avenge its death by helping to discover the murderer or to wreak vengeance for itself there is a widespread belief that those who die a violent death become malignant spirits and endanger the lives of those who come near the haunted spot the woman who dies in childbirth becomes a pontianak and threatens the life of human beings people resort to magical or religious means of repelling their spiritual dangers evil spirits side by side with the doctrine of separable souls with which we have so far been concerned
exists the belief in a great host of unattached spirits these are not immanent souls that have become detached from their abodes but have instead every appearance of independent spirits these spirits are at first mainly malevolent side by side with them we find the spirits of the dead as hostile beings at a higher stage the spirits of dead kinsmen are no longer unfriendly nor yet all non human spirits as fetishes naguals see totem familiar spirits gods or demi gods see also demonology they enter into relations with man on the other hand there still subsists a belief in innumerable evil spirits which manifest themselves in the phenomena of possession lycanthropy disease and so on the fear of evil spirits has given rise to ceremonies of expulsion of evils see exorcism designed to banish them from the community differences between animism and religion animism is commonly described as the most primitive form of religion but properly speaking it is not a religion at all animism is in the first instance an explanat
ion of phenomena rather than an attitude of mind toward the cause of them a philosophy rather than a religion the term may however be conveniently used to describe the early stage of religion in which people endeavour to set up relations between themselves and the unseen powers conceived as spirits but differing in many particulars from the gods of polytheism as an example of this stage in one of its aspects may be taken the european belief in the corn spirit which is however the object of magical rather than religious rites sir james g frazer in the golden bough has thus defined the character of the animistic pantheon they are restricted in their operations to definite departments of nature their names are general not proper their attributes are generic rather than individual in other words there is an indefinite number of spirits of each class and the individuals of a class are much alike they have no definitely marked individuality no accepted traditions are current as to their origin life and character th
is stage of religion is well illustrated by the native american custom of offering sacrifice to certain rocks or whirlpools or to the indwelling spirits connected with them the rite is only performed in the neighbourhood of the object it is an incident of a canoe or other voyage and is not intended to secure any benefits beyond a safe passage past the object in question the spirit to be propitiated has a purely local sphere of influence and powers of a very limited nature animistic in many of their features too are the temporary gods of fetishism naguals or familiars genii and even the dead who receive a cult with the rise of a belief in departmental gods comes the age of polytheism the belief in elemental spirits may still persist but they fall into the background and receive no cult animism and the origin of religion two animistic theories of the origin of religion have been put forward the one often termed the ghost theory mainly associated with the name of herbert spencer but also maintained by grant alle
n refers the beginning of religion to the cult of dead human beings the other put forward by dr e b tylor makes the foundation of all religion animistic but recognizes the non human character of polytheistic gods although ancestor worship or more broadly the cult of the dead has in many cases overshadowed other cults or even extinguished them we have no warrant even in these cases for asserting its priority but rather the reverse in the majority of cases the pantheon is made up by a multitude of spirits in human sometimes in animal form which bear no signs of ever having been incarnate sun gods and moon goddesses gods of fire wind and water gods of the sea and above all gods of the sky show no signs of having been ghost gods at any period in their history they may it is true be associated with ghost gods in australia it cannot even be asserted that the gods are spirits at all much less that they are the spirits of dead men they are simply magnified magicians super men who have never died we have no ground the
refore for regarding the cult of the dead as the origin of religion in this area this conclusion is the more probable as ancestor worship and the cult of the dead generally cannot be said to exist in australia the more general view that polytheistic and other gods are the elemental and other spirits of the later stages of animistic creeds is equally inapplicable to australia where the belief seems to be neither animistic nor even animatistic in character but we are hardly justified in arguing from the case of australia to a general conclusion as to the origin of religious ideas in all other parts of the world it is perhaps safest to say that the science of religions has no data on which to go in formulating conclusions as to the original form of the objects of religious emotion it must be remembered that not only is it very difficult to get precise information of the subject of the religious ideas of people of some other cultures perhaps for the simple reason that the ideas themselves are far from precise but
also that as has been pointed out above the conception of spiritual often approximates very closely to that of material where the soul is regarded as no more than a finer sort of matter it will obviously be far from easy to decide whether the gods are spiritual or material even therefore if we can say that at the present day the gods are entirely spiritual it is clearly possible to maintain that they have been spiritualized pari passu with the increasing importance of the animistic view of nature and of the greater prominence of eschatological beliefs the animistic origin of religion is therefore not proven animism and mythology little need be said on the relation of animism and mythology while a large part of mythology has an animistic basis it is possible to believe e g in a sky world peopled by corporeal beings as well as by spirits of the dead the latter may even be entirely absent the mythology of the australians relates largely to corporeal non spiritual beings stories of transformation deluge mytholog
y and doom myths or myths of the origin of death have not necessarily any animistic basis at the same time with the rise of ideas as to a future life and spiritual beings this field of mythology is immensely widened though it cannot be said that a rich mythology is necessarily genetically associated with or combined with belief in many spiritual beings animism in philosophy the term animism has been applied to many different philosophical systems it is used to describe aristotle s view of the relation of soul and body held also by the stoics and scholastics on the other hand monadology leibniz has also been termed animistic the name is most commonly applied to vitalism a view mainly associated with georg ernst stahl and revived by f bouillier one eight one three one eight nine nine which makes life or life and mind the directive principle in evolution and growth holding that all cannot be traced back to chemical and mechanical processes but that there is a directive force which guides energy without altering
its amount an entirely different class of ideas also termed animistic is the belief in the world soul held by plato schelling and others tylor tylor argued that non western societies relied on animism to explain why things happen he further argued that animism is the earliest form of religion and reveals that humans developed religions in order to explain things at the time that tylor wrote this theory was politically radical because it made the claim that non western peoples and in particular non christian heathens in fact do have religion however since the publication of primitive culture tylor s theories have come under criticism from three quarters first some have questioned whether the beliefs of diverse peoples living in different parts of the world and not communicating with one another can be lumped together as one kind of religion second some have questioned whether the basic function of religion really is to explain the universe critics like marrett and emil durkheim argued that religious beliefs ha
ve emotional and social rather than intellectual functions finally many now see tylor s theories as ethnocentric not only was he imposing a contemporary and western view of religion that it explains the inexplicable on non western cultures he was also telling the story of a progression from religion which provides poor explanations to science which provides good explanations see cultural evolution list of phenomena believed to lead to animism lists of phenomena from the contemplation of which the savage was led to believe in animism have been given by sir e b tylor herbert spencer andrew lang and others an animated controversy arose between the former as to the priority of their respective lists among these phenomena are trance unconsciousness sickness death clairvoyance dreams apparitions of the dead wraiths hallucinations echoes shadows reflections the new animism in an article entitled revisiting animism nurit bird david builds on the work of irving hallowell by discussing the animist worldview and lifeway
of the nayaka of india hallowell had learnt from the ojibwa of southern central canada that the humans are only one kind of person among many there are also rock persons eagle persons and so on hallowell and bird david discuss the ways in which particular indigenous cultures know how to relate to particular persons individuals or groups there is no need to talk of metaphysics or impute non empirical beliefs in discussing animism what is required is an openness to consider that humans are neither separate from the world nor distinct from other kinds of being in most significant ways the new animism also makes considerably more sense of attempts to understand totemism as an understanding that humans are not only closely related to other humans but also to particular animals plants etc it also helps by providing a term for the communities among whom shamans work they are animists not shamanists shamans are employed among animist communities to engage or mediate with other than human persons in situations that w
ould be fraught or dangerous for un initiated untrained or non skillful people the ism of animism should not suggest an overly systematic approach but this is true of the lived reality of most religious people but it is preferable to the term shamanism which has led many commentators to construct an elaborate system out of the everyday practices of animists and those they employ to engage with other than human persons the new animism is most fully discussed in a recent book by graham harvey animism respecting the living world but it is also significant in the animist realist novels now being written among many indigenous communities worldwide the term animist realism was coined by harry garuba a nigerian scholar of literature in comparison with magical realism that describes works such as marquez s one hundred years of solitude see also hylozoism midewiwin monism panentheism panpsychism pantheism suggested reading the story of b by daniel quinn references bird david nurit one nine nine one animism revisited p

fered to an earthquake that shook the city that day or the infant s poor health vivaldi s official church baptism didn t take place until two months later his father giovanni battista a barber before becoming a professional violinist taught him to play violin at first then toured venice playing violin with his father vivaldi had a medical problem which he called the tightening of the chest asthma his medical problem however did not prevent him from learning to play the violin compose and take part in any musical activities at the age of one five one six nine three he began studying to become a priest in one seven zero three one zero years later at the age of two five vivaldi was ordained as a priest soon nicknamed il prete rosso the red priest probably because of his red hair not long after in one seven zero four he was given a dispensation from celebrating the holy mass because of his ill health he apparently suffered from asthma a breathing disorder and in late one seven zero six he withdrew from the priest
hood and became maestro di violino at an orphanage for girls called the pio ospedale della piet in venice shortly after his appointment the orphans began to gain appreciation and esteem abroad too vivaldi wrote for them most of his concertos cantatas and sacred music in one seven zero five the first collection raccolta of his works was published many others would follow at the orphanage he covered several different duties with the only interruption for his many travels in one seven zero nine he was let go for economic reasons but in one seven one one he was offered the job again and in one seven one three became responsible for the musical activity of the institute vivaldi was promoted to maestro de concerti in one seven one six it was during these years that vivaldi wrote much of his music including many operas and concertos in one seven one eight vivaldi began to travel despite his frequent travels the piet paid him to write two concertos a month for the orchestra and to rehearse with them at least four tim
es when in venice the piet s records show that he was paid for one four zero concertos between one seven two three and one seven two nine not so well known is the fact that most of his repertoire was re discovered only in the first half of the two zero th century in turin and genoa but was published in the second half vivaldi s music is innovative breaking a consolidated tradition in schemes he gave brightness to the formal and the rhythmic structure of the concerto repeatedly looking for harmonic contrasts and invented innovative melodies and themes moreover vivaldi was able to compose non academic music particularly meant to be appreciated by the wide public and not only by an intellectual minority the joyful appearance of his music reveals in this regard a transmissible joy of composing these are among the causes of the vast popularity of his music this popularity soon made him famous also in countries like france at the time very independent in its musical taste vivaldi is considered one of the composers
who brought baroque music with its typical contrast among heavy sonorities to evolve into a classical style johann sebastian bach was deeply influenced by vivaldi s concertos and arias recalled in his passions and cantatas bach transcribed a number of vivaldi s concertos for solo keyboard along with a number for orchestra including the famous concerto for four violins and violoncello strings and continuo rv five eight zero however not all musicians have shown the same enthusiasm igor stravinsky provocatively said that vivaldi had not written hundreds of concertos but one concerto hundreds of times despite his priestly status he is supposed to have had possible love affairs one of which was with the singer anna giraud with whom he was suspected of reusing materials from old venetian operas which he only slightly adapted to the vocal capabilities of his proteg e this business caused him some troubles with other musicians like benedetto marcello who wrote a pamphlet against him there is no concrete evidence howe
ver that links vivaldi romantically to anyone vivaldi s life like those of many composers of the time ended in poverty his compositions no longer held the high esteem they once did in venice changing musical tastes quickly made them outmoded and vivaldi in response chose to sell off sizeable numbers of his manuscripts at paltry prices to finance a migration to vienna reasons for vivaldi s departure from venice are unclear but it seems likely that he wished to meet charles vi who adored his compositions vivaldi dedicated la cetra to charles in one seven two seven and take up the position of royal composer in his imperial court but shortly after vivaldi s arrival at vienna charles died this tragic stroke of bad luck left the composer without royal protection and a source of income vivaldi had to sell off more manuscripts to make ends meet and eventually died not long after in one seven four one he was given an unmarked pauper s grave the assumption that the young joseph haydn sang in the choir at vivaldi s buri

by god the jewish people called him father abraham and promised great things father of the people of israel through his son isaac the muslims regard ishmael as the father of the arabs in islam abraham is considered to be one of the most important of the many prophets sent by god in christian belief abraham is a model of faith and his intention to obey god by offering up isaac is seen as a foreshadowing of god s offering of his son jesus in islamic belief abraham obeyed god by offering up ishmael his original name was abram high exalted father leader standard hebrew avram tiberian hebrew a r m he was the foremost of the biblical patriarchs later in life he went by the name abraham there is no contemporary mention of his life and no source earlier than genesis mentions him according to calculations derived from the masoretic hebrew torah abraham was born one nine four eight years after creation and lived for one seven five years which would correspond to a life spanning from one eight one two bce to one six th

the hebrews his father terah came from ur of the chaldees popularly identified only since one nine two seven thanks to sir charles woolley with the ancient city in southern mesopotamia which was under the rule of the chaldeans although josephus islamic tradition and jewish authorities like maimonides all concur that ur of the khaldis was in northern mesopotamia where is now kurdistan identified with urartu urfa and kutha respectively this is in keeping with the local tradition that abraham was born in urfa or with the nearby urkesh which others identify with ur of the chaldees they also say chaldees refers to a group of gods called khaldis abram migrated to harran apparently the classical carrhae on a branch of the habor thence after a short stay he his wife sarai lot the son of abram s brother haran and all their followers departed for canaan there are two cities possibly identifiable with the biblical ur neither far from haran ura and urfa a northern ur also being mentioned in tablets at ugarit nuzi and eb

fertile land lying east of the jordan river while abram after receiving another promise from yahweh moved down to the oaks of mamre in hebron and built an altar in the subsequent history of lot and the destruction of sodom and gomorrah abram appears prominently in a passage where he intercedes with yahweh on behalf of sodom and is promised that if ten righteous men can be found therein the city shall be preserved one eight one six three three driven by a famine to take refuge in egypt two six one one four one five seven four two one abram feared lest his wife s beauty should arouse the evil designs of the egyptians and thus endanger his own safety and alleged that sarai was his sister this did not save her from the pharaoh who took her into the royal harem and enriched abram with herds and servants but when yahweh plagued pharaoh and his house with great plagues abram and sarai left egypt there are two other parallel tales in genesis of a wife confused for a sister genesis two zero two one and two six describ

anently away from abram by sarah chapter two one the name abraham was given to abram and the name sarah to sarai at the same time as the covenant of circumcision chapter one seven which is practiced in judaism and islam to this day at this time abraham was promised not only many descendants but descendants through sarah specifically as well as the land where he was living which was to belong to his descendants the covenant was to be fulfilled through isaac though god promised that ishmael would become a great nation as well the covenant of circumcision unlike the earlier promise was two sided and conditional if abraham and his descendants fulfilled their part of the covenant yahweh would be their god and give them the land the promise of a son to abraham made sarah laugh which became the name of the son of promise isaac sarah herself laughs at the idea when yahweh appears to abraham at mamre one eight one one five and when the child is born cries god hath made me laugh every one that heareth will laugh at me
two one six in genesis one eight abraham pleads with god not to destroy sodom and god agrees that he would not destroy the city if there were five zero righteous people in it or four five or three zero two zero even one zero righteous people abraham s nephew lot had been living in sodom some time after the birth of isaac abraham was commanded by god to offer his son up as a sacrifice in the land of moriah proceeding to obey he was prevented by an angel as he was about to sacrifice his son and slew a ram which he found on the spot as a reward for his obedience he received another promise of a numerous seed and abundant prosperity two two then he returned to beersheba the near sacrifice of isaac is one of the most challenging and perhaps ethically troublesome parts of the bible according to josephus isaac is two five years old at the time of the sacrifice or akedah while the talmudic sages teach that isaac is three seven in either case isaac is a fully grown man old enough to prevent the elderly abraham who is
one two five or one three seven years old from tying him up had he wanted to resist the primary interest of the narrative now turns to isaac to his only son two two two one two abraham gave all he had and dismissed the sons of his concubines to the lands outside canaan they were thus regarded as less intimately related to isaac and his descendants two five one six see also midianites sheba sarah died at an old age and was buried in the cave of machpelah near hebron which abraham had purchased along with the adjoining field from ephron the hittite genesis two three here abraham himself was buried centuries later the tomb became a place of pilgrimage and muslims later built an islamic mosque inside the site abraham is considered the father of the jewish nation as their first patriarch and having a son isaac who in turn begat jacob and from there the twelve tribes to father the nation god tested abraham with ten tests the greatest being his willingness to sacrifice his son isaac god promised the land of israel t
o his children and that is the first claim of the jews to israel judaism ascribes a special trait to each patriarch abraham s had kindness because of this judaism considers kindness to be an inherent jewish trait jewish tradition teaches the origins of abraham s monotheism his father terah owned a store that sold idols abraham at the age of three started to question their authenticity this culminated in abraham destroying some idols abraham was then brought to the king and sentenced to death along with his brother haran unless they recanted their position abraham did not and was thrown into a fire when abraham exited unscathed haran also would not recant and was thrown into the fire haran who did not truly believe died in the fire this is hinted at in genesis one one two eight abraham then went to the city of haran with his father and brother his father died there god spoke to abraham for the first time and told him of great things he would give him if he would leave haran abraham did he was seventy five duri

therefore greatly mistaken mark one two two six two seven by faith abraham when he was tested offered up isaac and he who had received the promises offered up his only begotten son of whom it was said in isaac your seed shall be called concluding that god was able to raise him up even from the dead from which he also received him in a figurative sense hebrews one one one seven one nine the orthodox baptist and traditional protestant view in christianity is that the chief promise made to abraham in genesis one two is that through abraham s seed all the people of earth would be blessed this promise was fulfilled through abraham s seed jesus it is also a consequence of this promise that christianity is open to people of all races and not limited to the jews the roman catholic church calls abraham our father in faith in the eucharistic prayer called the roman canon recited during the mass see abraham in liturgy christian tradition sees abraham as a figure of god and abraham s attempt to offer up isaac is a fores
