Actia

In Ancient Roman religious tradition, Actia (Greek: Ἄκτια) was a festival of Apollo, celebrated at Nicopolis in Epirus, with wrestling, musical contests, horse racing, and sea battles. It was reestablished by Augustus, in commemoration of his victory over Mark Antony off Actium in 31 BC; that it was probably the revival of an ancient festival is suggested by the celebrated temple of Apollo at Actium, which is mentioned by Thucydides, and Strabo, and which was enlarged by Augustus. The games instituted by Augustus were celebrated every four years (πενταετηρίς, ludi quinquennales); they received the title of a sacred agon and were also called Olympia.
