days each, and indicated by the letters A–H. Each day was marked by a certain letter to show its nature; thus the letters F., N., N.P., F.P., Q. Rex C.F., C., EN., stood for , , in some unexplained sense, , , and . The were partly fasti and partly nefasti. Ovid's Fasti is a poetical description of the Roman festivals of the first six months, written to illustrate the Fasti published by Julius Caesar after he remodelled the Roman year. Upon the cultivators fewer feasts, sacrifices, ceremonies and holidays were enjoined than on the inhabitants of cities; and the rustic fasti contained little more than the ceremonies of the calends, and , the fairs, signs of zodiac, increase and decrease of the days, the tutelary gods of each month, and certain directions for rustic labours to be performed each month. Extant fasti A considerable number of fasti have been discovered. The Praenestine calendar (Fasti praenestini), discovered in 1770, arranged by the famous grammarian Verrius Flaccus, contains the months of January, March, April, and December, and a portion of February. The tablets give an account of festivals, and also of the triumphs of Augustus and Tiberius. There are still two complete calendars in existence, an official list by Philocalus (354), and a Christian version of the official calendar, made by Polemius Silvius (448). Modern fasti In modern times the word fasti and its reflexes in modern languages have been used formally for quasi-official writings of a diachronic character. Some examples are the official history and traditions of a regiment, in Scotland the Fasti Ecclesiae Scoticanae: the succession of ministers in the Church of Scotland from the reformation, the first volume of which was produced in 1915 and which is still updated at irregular intervals. Between 1946 and 1987 the International Association for Classical Archaeology (AIAC) published the Fasti Archaeologici. It contained summary notices of excavations through the area of the Roman Empire. The Fasti went online and discontinued paper publication in 2000: the Fasti Online now contains reports on excavations since the year 2000 in 13 countries, particularly Italy, Bulgaria, Romania, Macedonia, Malta and Albania. It is accompanied by an online journal, Fasti Online Documents & Research, which publishes full and interim reports on archaeological sites in Italy. See under "External links" below.
