Lupercalia (n.)
Roman festival held Feb. 15 in honor of Lupercus a god (identified with Lycean Pan, hence regarded as a protective divinity of shepherds) who had a grotto at the foot of the Palatine Hill, from Latin Lupercalia (plural), from Lupercalis "pertaining to Lupercus," whose name derives from lupus "wolf" (see wolf (n.)). The ceremony is regarded as dating from distant antiquity. Related: Lupercalian.
