what is the letter m in roman numerals
M The Roman numeral â…¯ represents the number 1000, though it was not used in Roman times. There is, however, scant evidence that the letter was later introduced in the early centuries by the Romans. [3]
Julian calendar The Romans later renamed months after Julius Caesar and Augustus, renaming Quintilis as "Iulius" (July)[8] in 44 BC and Sextilis as "Augustus" (August) in 8 BC. Quintilis was renamed to honour Caesar because it was the month of his birth.[68] According to a senatus consultum quoted by Macrobius, Sextilis was renamed to honour Augustus because several of the most significant events in his rise to power, culminating in the fall of Alexandria, occurred in that month.[69]
