His father may have been the Gaius Megabocchus mentioned by Cicero[1] as condemned for extortion in Sardinia.
The son is also named by Cicero in a letter to Atticus[2] dated April 59 BC, during Julius Caesar's first consulship.
Megabocchus is there connected with an unsuccessful candidate for the year's other consular office who was a close associate of the elder Crassus.
[3] During the Battle of Carrhae, Megabocchus is among those who ride with young Crassus on a last desperate cavalry foray.
After sustaining heavy casualties, the Romans and their Gallic auxiliaries retreat to a sand dune, where hope is soon lost under the constant barrage of Parthian arrows.
