(RNN) - On Valentine's Day, it's typical to see mushy displays of affection from couples, friends and family.
It's the day we tell each other - in sickeningly, loving detail - how much we care and show it with heart-shaped chocolate boxes and shiny jewelry.
Saint Valentine's Day is named after a martyr in ancient Rome. There are a few stories about different St. Valentine's, but the most popular account tells of a priest under the reign of Emperor Claudius II. When the emperor decided young, single men made better soldiers, he outlawed marriage for them. Valentine continued to marry young Christian couples in secret and when discovered, he was put to death.
Another version tells of a Valentine imprisoned for trying to help persecuted Christians escape Roman prisons where they were tortured and beaten. He fell in love with a girl, possibly the jailer's daughter. He wrote the first "valentine" to her from prison, signing it "From your Valentine."
The saint wouldn't recognize his own feast day today. Valentine's Day is now celebrated world-wide and in a variety of cultural fashions. Whether you're planning a nice evening out, or a quiet night in, love will be all around this Feb. 14.
