Dio Cassius

Dio Cassius also known as Cassius Dio was born and raised at Nicaea in Bithynia. At various points in his life he was a Senator, Governor of Smyrna, a Suffect Consul, and later a proconsul in Africa Proconsularis and Pannonia. He published 80 volumes of the history on ancient Rome, beginning with the arrival of Aeneas in Italy. The volumes documented the subsequent founding of Rome (753 BCE), the formation of the Republic (509 BCE), and the creation of the Empire (27 BCE), up until 229 CE. Written in Ancient Greek over 22 years, Dio's work covers approximately 1,000 years of history. Many of his 80 books have survived intact, or as fragments, providing modern scholars with a detailed perspective on Roman history (wikipedia). Dio Cassius was either the grandfather or great-grandfather of Cassius Dio, a consul in 291 CE.
