Augustus after his victory enlarged the temple, and revived the ancient festival, which was henceforth celebrated once in five years (πενταετηρίς, ludi quinquennales), with musical and gymnastic contests, and horse races. We learn from a Greek inscription found on the site of Actium, and which is probably prior to the time of Augustus, that the chief priest of the temple was called Ἱεραπόλος, and that his name was employed in official documents, like that of the first Archon at Athens, to mark the date.
