Terentia gens

The gens Terentia was a plebeian family at ancient Rome. Dionysius mentions a Gaius Terentius Arsa, tribune of the plebs in 462 BC, but Livy calls him Terentilius, and from inscriptions this would seem to be a separate gens. No other Terentii appear in history until the time of the Second Punic War. Gaius Terentius Varro, one of the Roman commanders at the Battle of Cannae in 216 BC, was the first to hold the consulship. Members of this family are found as late as the third century AD.

Origin
The antiquarian Varro derived the nomen Terentius from a Sabine word, terenus, meaning "soft". However, Chase suggests a Latin origin, from terens, one who grinds or threshes, and classifies the name among those gentilicia which either originated at Rome, or cannot be shown to have come from anywhere else.

Praenomina
The chief praenomina of the Terentii were Marcus, Gaius, Aulus, and Publius, all of which were very common throughout Roman history. The Culleones used Quintus, and other names occur occasionally.

Branches and cognomina
The main families of the Terentii used the cognomina Culleo, Lucanus, and Varro. Of these, Varro seems to be derived from the same root as the Latin baro, a fool; Culleo refers to a leather sack or pouch, and may have referred to a leatherworker; while Lucanus signified an inhabitant of Lucania, and must have been given to one of the Terentii who either came from or perhaps had some connection with that region, or its people.

He held a naval command under Pompeius during the Third Mithridatic War and the War Against the Pirates, and was Pompeius' legate in Spain during the Civil War. Although pardoned by Caesar, he was proscribed by the Second Triumvirate, but eventually received Octavian's protection. Although most of his vast literary output was destroyed, his treatise on agriculture and part of one on the Latin language survive.
 * Publius Terentius Varro Atacinus, a celebrated poet of the first century BC. He wrote an Argonautica, a work on geography, one on using animals to predict the weather, and works on Europe, the Gallic Wars, love, and epigrams, but only fragments of his work survive.

Praetor peregrinus in 187, he required Latins residing at Rome to return to their native towns, and perhaps oversaw the investigation and trial of Lucius Cornelius Scipio Asiaticus, although this is now in doubt.

From 43 he served under Marcus Aemilius Lepidus, and was assigned to guard a passage of the Alps against Marcus Antonius, but offered no resistance when Anonius' forces crossed.

 * Quintus Terentius, one of two envoys dispatched by the senate in 218 BC to recall the consul elect Gaius Flaminius, whose election and inauguration were heralded by terrible omens. Flaminius ignored the summons, and later perished with his army at Lake Trasimine.
 * Lucius Terentius Massaliota, plebeian aedile in 200 BC, and praetor in 187 BC, in which year he was assigned the province of Sicily. He is probably the same Lucius Terentius who was an ambassador in 196. He was a military tribune in Hispania Citerior from 182 to 180.
 * Lucius Terentius, one of the ambassadors sent to Antiochus III in 196 BC, is probably to be identified with Lucius Terentius Massaliota.

 * Lucius Terentius, a close friend of the young Pompeius. While the two were serving together under Pompeius' father in 87 BC, the consul Lucius Cornelius Cinna is reported to have bribed Terentius to kill his friend, but Pompeius learned of the plot and narrowly avoided death.
