Vinicius, Tiberius and Varus led Roman forces in multiple punitive campaigns, before sustaining a major defeat at the hands of Arminius in the Battle of the Teutoburg Forest.
Concurrently, the Roman Empire fought the Bellum Batonianum against a rebelling alliance of native peoples led by Bato the Daesitiate in Illyricum, which was suppressed in AD 9.
Literary works from the 0s include works from the ancient Roman poet Ovid; the Ars Amatoria, an instructional elegy series in three books, Metamorphoses, a poem which chronicles the history of the world from its creation to the deification of Julius Caesar within a loose mythico-historical framework, and Ibis, a curse poem written during his years in exile across the Black Sea for an offense against Augustus.
The Anno Domini (AD) calendar era which numbers these years 1-9 was devised by Dionysius Exiguus in 525, and became widely used in Christian Europe in the 9th century.
[2][3] Modern scholars disagree with Dionysius' calculations, placing the event several years earlier (see Chronology of Jesus).
