Lupercus, an ancient Italian god, worshipped by shepherds as the protector of their flocks against wolves.
The Grotto of Lupercus is the oldest sanctuary of kingly Rome.
Lupercus was, primarily, the god of shepherds, said to have been so called because he protected the flocks from wolves.
Faunus is frequently called Inuus or the fertilizer, and Lupercus or the one who wards off wolves.
The Lupercal was the sanctuary of Lupercus ('wolf-repeller'), an old Roman shepherd god.
As such he is akin to or identical with Inuus (“fructifier”) and Lupercus (see Lupercalia).
