Quintus Curtius Rufus, the Roman historian, wrote the only life in Latin of Alexander the
Great. The author's identity and the date of composition of the work have been the subject
of great debate. However, the evidence of recent years suggests he was a soldier and
politician who rose from obscurity to a senatorial role under Tiberius (AD 14-37). However,
the fall of the emperor's chief minister, Sejanus, brought his political career temporarily
to an end and he turned to writing.
