You must read Rev. Joseph Abrahamson’s post on the origins and history of St. Valentine’s Day. It’s part of his series that we’ve often linked to on Christian holidays that are mistakenly claimed to have pagan origins. He shows that St. Valentine’s Day is not based on Roman festivals but on a day commemorating the death of a Christian martyr, though which of many saints with that name is a matter of some confusion. The question, though, is how this saint’s day became associated with love and romance.
It turns out that the connection comes from one of my favorite authors, Geoffrey Chaucer!
After an extensive discussion that you should read, Rev. Abrahamson comes to this:
The first author to associate Valentine’s Day with romance was Chaucer. We are now more than a thousand years after the martyrdom of St. Valentine. Geoffrey Chaucer (ca. 1343-1400). from The Parliament of Fowls.
