number 4 in roman numerals on clock faces

title: Roman numerals text: use of Roman numerals persists in some minor applications to this day. The original pattern for Roman numerals used the symbols I, V, and X (1, 5, and 10) as simple tally marks. Each marker for 1 () added a unit value up to 5 (), and was then added to () to make the numbers from 6 to 9: The numerals for 4 () and 9 () proved problematic (among other things, they are easily confused with and , especially at a quick glance), and are generally replaced with (one less than 5) and (one less than 10). This title: Clock face text: combination, with the prior indicating the hour and the latter the minute. Longcase clocks (grandfather clocks) typically use Roman numerals for the hours. Clocks using only Arabic numerals first began to appear in the mid-18th century. The clock face is so familiar that the numbers are often omitted and replaced with applied indices (undifferentiated hour marks), particularly in the case of watches. Occasionally, markings of any sort are dispensed with, and the time is read by the angles of the hands. Most modern clocks have the numbers 1 through 12 printed at equally spaced intervals around the periphery of the title: Legacy of the Roman Empire text: meaning before midday) and P.M. ("post-meridiem", meaning past midday). The Romans also started the practice used worldwide today of a new day beginning at midnight. Roman numerals continued as the primary way of writing numbers in Europe until the 14th century, when they were largely replaced in common usage by Hindu-Arabic numerals. The Roman numeral system continues to be widely used, however, in certain formal and minor contexts, such as on clock faces, coins, in the year of construction on cornerstone inscriptions, and in generational suffixes (such as Louis XIV or William Howard Taft IV). According to the Royal Spanish title: St Mark's Clock text: changed the numbering of the clock face from the old Italian style (I to XXIIII in Roman numerals) to the 12-hour style, using two sets of Arabic numerals, with 12 at the top and bottom of the dial. He received the old mechanism and dial as part of his payment. Ferracina's new movement reflected the great advances in horology that had been made since the original clock had been installed. A Graham dead-beat escapement replaced the foliot, with a 4m pendulum, mounted away from the central arbor, beating once every 1.97 seconds. The new striking system used a new pair title: Roman timekeeping text: be writing from a Hebrew culture, nor presuming a purely Jewish audience, and so the more likely time reference would be according to Roman counting. To indicate that it is a day or night hour Romans used expressions such as for example "prima diei hora", "prima noctis hora", "hora prima noctis". The Romans divided the night into four watches, (Latin "vigiliae" plural), following the Greek practice (Greek φυλακή), since, as Vegetius explains, a city-guard could not stand watch all night. For example, "in the fourth watch of night" ("quarta vigilia noctis") meant just before dawn. According to many sources each
