# Atia gens

The gens Atia, sometimes written Attia, was a minor plebeian family at Ancient Rome. The first of this gens to achieve prominence was Lucius Atius, a military tribune in 178 BC. Several of the Atii served in the Civil War between Caesar and Pompeius. The gens Attia of imperial times may be descended from this family, although its members lived nearly a century after the more notable Atii, and are not known to have been related.

## Origin

None of the Atii are mentioned in history prior to the second century BC, and none of them ever held the consulship, but owing to its connection with Augustus, Vergil pretended this gens to be descended from Atys, a friend of Ascanius, the son of Aeneas, or one of the kings of Alba Longa supposedly descended from Ascanius.

## Praenomina

The Atii mentioned in history bore the most common praenomina, including Lucius, Gaius, Marcus, Publius, and Quintus.

## Branches and cognomina

The only cognomina found among the more notable Atii are Balbus, Celsus, Rufus, and Varus, of which only Balbus appears on coins. The Atii Balbi were from the city of Aricia. The Venetian scholar Paulus Manutius conjectured that the family of the Labieni belonged to the Atia gens, which opinion was followed by some modern writers. However, Spanheim pointed out that there was no authority for this. Labienus is not found as the cognomen of any person named Atius, nor as a surname of any other gens, but is instead the nomen of a separate gens.
