Biography
Gaius Acilius was a Roman senator and historian active in the mid-2nd century BC, a time when Rome was increasingly interacting with the Greek-speaking world. He is most recognized for his bilingual skills and his role as an interpreter in 155 BC, when Athens sent three major philosophers—Carneades, Diogenes of Babylon, and Critolaus—to Rome to argue before the Senate about a fine imposed on Athens. Acilius acted as their official interpreter, showing a rare fluency in Greek for a Roman senator of his time.
Acilius wrote a history of Rome in Greek, a nod to the cultural prestige Greek had among educated Romans and a way to reach an audience beyond Rome itself. His work covered events up to at least 184 BC, as mentioned by Dionysius of Halicarnassus, and is thought to have been shared around 142 BC, based on Livy's references. Writing Roman history in Greek placed Acilius among a small group of early Roman historians who followed Greek literary styles, similar to Quintus Fabius Pictor.
Acilius's history didn't survive intact. A Latin translation was made by a writer known as Claudius, possibly Claudius Quadrigarius, a historian from the late 2nd or early 1st century BC. This translation helped circulate Acilius's material among Latin readers, although only fragments remain today. Plutarch used Acilius's history in his Life of Romulus, where it is cited concerning Rome's legendary past, indicating that the work covered both early Roman traditions and more recent events.
As a senator, Acilius had a social and political status that gave him access to official records, oral traditions, and the discussions of Rome's ruling class. His specific career in the Senate isn't detailed beyond his role as an interpreter in 155 BC, but his rank confirms he was part of Rome's elite. His Greek skills, connection to key events, and literary ambitions make him a notable figure in Roman aristocracy engaging with Greek culture during the Republic's middle period.
Before Fame
We don't have any surviving ancient records about the early life of Gaius Acilius, so we don't know anything about his upbringing, education, or how he entered the Senate. He was part of the Acilia gens, a plebeian family that rose to senatorial status during the Republic. In the mid-2nd century BC, Rome's upper classes increasingly pursued Greek education, often sending their sons to study with Greek tutors or learning from Greek-speaking ambassadors, freedmen, and scholars who came to Rome.
Acilius's clear fluency in Greek suggests he received the type of education that was becoming popular among Rome's elite at the time, focusing on Greek language, rhetoric, and philosophy. This background enabled him to engage directly with the intellectual trends from Athens and the broader Greek world, which eventually led to his role as an interpreter when Athens sent its famous philosophical mission to the Senate. His later choice to write Roman history in Greek shows the same intellectual foundation that influenced his public duties in 155 BC.
