The history of Valentine's Day is a tricky one to tackle as its roots are clouded by many wondrous fables. It has been said that the actual holiday has deep roots in the ancient Roman festival of Lupercalia. Lupercalia is the celebration of fertility which occurred annually on February 15th. It wasn't until 496, under Pope Gelasius I, that the feast was changed to February 14th and said to be Saint Valentine's Day. But which Saint was Valentine? Sadly this is a mystery, when one looks at the Catholic Encyclopedia, they will find three Christian saints by that very name. (it is a lovely name isn't it) All three were martyred on February 14th, which only adds to the mystery.
Some scholars think the St. Valentine, to which the feast and day was for, belongs to a priest who lost favor of the Roman Emperor Claudius III around 270 (A relative of mine. :) The legend explains that Claudius III prohibited marriage for all young men. He wanted them to be soldiers, not husbands. It was at this time that St. Valentine began to secretly wed people. He was later taken to jail where he fell in love with the daughter of the jailer. (Oh love so wonderful) The legends ends with a letter he sent, which was signed: From Your Valentine. Oh so beautiful. Whether it is true or not...it does make for a lovely story.
Everyone have a beautiful day.
