Lubercus or Luberkus was a god in Roman mythology.
Lubercus was a protector of the farmers, harvesting and packs of Wild Animals. Every year on 15 February in honor of him, the Romans held the Lupercalia.
He helped the wolf take care of Romulus and Remus; this is why Lupercalia was a celebration that helped pregnant women.
In Greek mythology he was counterpart of the god Faun and after the god Pan.
