The Lupercalia recalled the primitive days of Rome's existence,
when, according to Roman tradition, a small community of shepherds lived
in thatched huts on the Palatine hill, ruled by the founder of Rome, Romulus.
Dionysius of Halicarnassus tells us that in his day (first century BC),
one of these huts, made out of sticks and reeds, stood on the slope of
the Palatine toward the Circus Maximus. This hut was honored
as a sacred place and was kept in good repair (Roman Antiquities 1.79.11).

This primitive settlement, however, was more than just a popular tradition; modern archaeology has discovered the post holes of huts dating to the eighth century BC (the traditional date of Rome's foundation was 753 BC). It seems probable that the name of the festival was derived from lupus ("wolf"). This derivation makes sense for a festival that was connected with a settlement of shepherds, whose most feared predator was the wolf.
TIn general, the ancients viewed the Lupercalia as a purification and fertility rite. The ritual involved the sacrifice of goats and a dog in the Lupercal by priests called Luperci,1who smeared the foreheads of two noble young men with the blood of the sacrificed animals and then wiped it off. At this point, the youths were required to laugh. Then the luperci, clothed in loincloths, ran about the area, lashing everyone they met with strips of skin from the sacrificed goats. Young wives were particularly eager to receive these blows, because it was believed that the ritual promoted fertility and easy childbirth. These ceremonies were accompanied by much revelry and drinking.
The Lupercalia was so popular that it survived the onset of Christianity,
but in a different form. In 494 AD, the Pope made February 15 the
feast of the Purification of the Virgin Mary.
