The grammarian Festus says that it was named for a Cispius Laevus of Anagnia, of the Publilia voting tribe (tribus).
Sometime after Cispius's tribunate, most likely in early 56, he was defended by Cicero on a charge of electoral corruption (ambitus) and convicted.
[8] Lucius Cispius, probably with the cognomen Laevus, was a commander of the fleet (praefectus classis) in 46 BC, serving under Julius Caesar.
It is possible that he was the son of Marcus Cispius (above), though this filiation would place them on opposite sides in the civil war.
[9] In 43, a Cispius Laevus was a legate of Munatius Plancus, carrying dispatches to Rome for him; this man was most likely Caesar's naval commander.
