 Descriptions of the Lupercalia festival of 44 BC attest to its continuity; Julius Caesar used it as the backdrop for his (possibly staged) public refusal of a golden crown offered to him by Mark Antony.The Lupercal cave was restored or rebuilt by Augustus, and has been speculated to be identical with a grotto discovered in 2007, below the remains of Augustus' residence; according to scholarly consensus, the grotto is a nymphaeum, not the Lupercal.The Lupercalia festival is marked on a calendar of 354 alongside traditional and Christian festivals.
