Did Geoffrey Chaucer invent Valentine’s Day? Yes and no.
St Valentine’s Day has been marked in liturgical calendars for centuries. As a Christian feast day, Valentine’s Day actually commemorates two Saint Valentines: Valentine of Rome and Valentine of Terni. (The Catholic Encyclopedia even speaks of a third Saint Valentine, who was martyred in Africa, but little else is known about him.)
