Saint Valentine, officially known as Saint Valentine of Rome, is a third-century Roman saint widely celebrated on February 14 and commonly associated with "courtly love".
At least three different Saint Valentines, all of them martyrs, are mentioned in the early martyrologies under date of 14 February. One is described as a priest at Rome, another as bishop of Interamna (modern Terni), and these two seem both to have suffered in the second half of the third century and to have been buried on the Flaminian Way, but at different distances from the city.
In William of Malmesbury's time what was known to the ancients as the Flaminian Gate of Rome and is now the Porta del Popolo, was called the Gate of St. Valentine.
