Dio of Alexandria
Dio of Alexandria (//; Greek: Δίων) was an Academic philosopher and a friend of Antiochus of Ascalon who lived in the first century BC. He was sent by his fellow-citizens as ambassador to Rome, to complain about the conduct of their king, Ptolemy XII Auletes. In Rome he was poisoned by the king's secret agents, and the strongest suspicion of the murder fell upon Marcus Caelius. The defence of Caelius in April 56 BC, the Pro Caelio, is considered one of Cicero's and indeed Rome's greatest orations.
