Today is the day of the Roman feast Lupercalia, and the day Saint Valentine was executed in martyrdom and consecrated by Love.
"Historians believe" Saint Valentine's story is most likely 3 different Valentines.
Because Saint Valentine is a revered Champion of Christianity the "right side of history" narrativists at best, grant him existence as a Bishop who continued to perform wedding ceremonies against the law.
As a celebration of fertility, a celebration of martyrdom, or a commercialized excuse to consolidate affection between couples; how do you celebrate the Legend of Saint Valentine?
If you dismiss this Holiday as Robin hood, why do you concede your folk lore to myth? Have you found better tales of meaning in harry potter and CNN?
