情人节的起源有基督教的传说，说瓦伦丁是个牧师，在古罗马的暴政统治下，偷偷地为想要结婚的青年男女按基督徒的仪式主持婚礼，结果被抓住处死。可是，这里还有另一种说法呢，说他是爱上了监狱看守的女儿，在临死前向她表白自己的心意……
according to one legend， valentine actually sent the first 'valentine' greeting himself.
while in prison， it is believed that valentine fell in love with a young girl —— who may have been his jailor's daughter —— who visited him during his confinement.
before his death， it is alleged that he wrote her a letter， which he signed 'from your valentine，' an expression that is still in use today.
although the truth behind the valentine legends is murky， the stories certainly emphasize his appeal as a sympathetic， heroic， and， most importantly， romantic figure. it's no surprise that by the middle ages， valentine was one of the most popular saints in england and france.
