Saint Valentine Feast Day - 14 February

Quoted from Wikipedia [1]:

Saint Valentine (Italian: San Valentino; Latin: Valentinus) was a 3rd-century Roman saint, commemorated in Western Christianity on February 14 and in Eastern Orthodoxy on July 6. From the High Middle Ages, his Saints' [sic] Day has been associated with a tradition of courtly love. He is also a patron saint of Terni, epilepsy and beekeepers.

Saint Valentine was a clergyman – either a priest or a bishop – in the Roman Empire who ministered to persecuted Christians. He was martyred and his body buried at a Christian cemetery on the Via Flaminia on February 14, which has been observed as the Feast of Saint Valentine (Saint Valentine's Day) since at least the eighth century.

...

At least two different Saint Valentines are mentioned in the early martyrologies. For Saint Valentine of Rome, along with Saint Valentine of Terni, "abstracts of the acts of the two saints were in nearly every church and monastery of Europe", according to Professor Jack B. Oruch of the University of Kansas.

At Teramo, [in Umbria, in the year 273,] the holy martyr Valentine, Bishop of that see. He was heavily flogged and committed to jail, but as he would not yield he was thrown out of the prison in the silence of midnight and beheaded by command of Placidus, Prefect of the city. There likewise, [in the year 273,] the holy martyrs Proculus, Ephebus, and Apollonius, who were watching by the body of holy Valentine when they were apprehended by order of Leontius, the consular, and slain with the sword.
