The gens Atia, sometimes written Attia, was a minor plebeian family at Ancient Rome.
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.
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.
[2][3][4][1][5][6] The Atii mentioned in history bore the most common praenomina, including Lucius, Gaius, Marcus, Publius, and Quintus.
[4] 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.
