The number zero does not have its own Roman numeral, but the word nulla (the Latin word meaning "none '') was used by medieval scholars in lieu of 0. Dionysius Exiguus was known to use nulla alongside Roman numerals in 525. About 725, Bede or one of his colleagues used the letter N, the initial of nulla or of nihil (the Latin word for "nothing ''), in a table of epacts, all written in Roman numerals.
