in Roman Antiquity, were solemn games instituted by Augustus, in memory of his victory over Mark Antony at Actium, held every fifth year, and celebrated in honour of Apollo, surnamed Actius. Hence also Actian Years, an era commencing from the battle of Actium, called the Era of Augustus. Virgil intimates them to have been instituted by Æneas, from that passage, Æn. iii. v. 280:

Actaque Illycis celebramus littera Indis.

But this he only does by way of compliment to Augustus; attributing that to the hero from whom he descended, which was done by the emperor himself; as is observed by Servius.
