Yep, it's another one of the pagan holidays that was adopted into christianity. I think the original pagan holiday was centered around sexual activity. I think that's what I read last year. I might be wrong - I might have to google it again.
Know what I just noticed? There's no love in valentine. But there is evil. v a l e n t i n e = an evil net
from an article from NPR From Feb. 13 to 15, the Romans celebrated the feast of Lupercalia. The men sacrificed a goat and a dog, then whipped women with the hides of the animals they had just slain. The Roman romantics "were drunk. They were naked," says Noel Lenski, a historian at the University of Colorado at Boulder. Young women would actually line up for the men to hit them, Lenski says. They believed this would make them fertile. The brutal fete included a matchmaking lottery, in which young men drew the names of women from a jar. The couple would then be, um, coupled up for the duration of the festival — or longer, if the match was right. The ancient Romans may also be responsible for the name of our modern day of love. Emperor Claudius II executed two men — both named Valentine — on Feb. 14 of different years in the 3rd century A.D. Their martyrdom was honored by the Catholic Church with the celebration of St. Valentine's Day.
