At the time, it was known as the Year of the Consulship of Caesar and Paullus. The denomination 1 for this year has been used since the early medieval period, when the Anno Dominicalendar era became the main method in Europe for naming years. The year before this is 1 BC in the widely used Julian calendar.
Livy writes his monumental History of Rome (
Ab Urbe Condita).
Birth of Jesus, as assigned by Dionysius Exiguus in his anno Domini era according to at least one scholar. However, most scholars think Dionysius placed the birth of Jesus in the previous year, 1 BC. Despite this, most modern scholars do not consider Dionysius' calculations authoritative. They placed the event several years earlier (see
Chronology of Jesus).
