St. Valentine's Day

From Wikipedia.org:

The feast of St. Valentine was first decreed in 496 by Pope Gelasius I, who included Valentine among those "... whose names are justly reverenced among men, but whose acts are known only to God." As Gelasius implied, nothing is known about the lives of any of these martyrs.

According to the Catholic Encyclopedia, the saint whose feast was celebrated on the ay now known as St. Valentine's Day was possibly one of three martyred men named Valentinus who lived in the late third century, during the reign of Emperor Claudius I (died 270): a priest in Rome, a bishop of Interamna (modern Terni), [or] a martyr in the Roman province of Africa.

Various dates are given for their martyrdoms: 269, 270 or 273.[1] As Gelasius implied, nothing is known about the lives of any of these martyrs. The name was a popular one in Late Antiquity, with its connotations of valens, "being strong".
