Other relics of him are in Whitefriar Street Carmelite Church, Dublin, Ireland, a popular place of pilgrimage, especially on Saint Valentine's Day, for those seeking love.

[16] The official Liturgical Calendar for the Dioceses of the United States identifies February 14 as the memorial of Saints Cyril and Methodius.

[18] There is a reference to his feast day on 14 February in one of the 9th century copies of the Martyrologium Hieronymianum,[19] which may have been compiled originally between 460 and 544 from earlier local sources, but the entry may be much later.

One was a Roman priest, another the bishop of Interamna (modern Terni, Italy) both buried along the Via Flaminia outside Rome, at different distances from the city.

[22] According to the official biography of the Diocese of Terni, Bishop Valentine was born and lived in Interamna and while on a temporary stay in Rome he was imprisoned, tortured, and martyred there on February 14, 269.

[26] The Roman martyrology lists only seven who died on days other than February 14: a priest from Viterbo (November 3); Valentine of Passau, papal missionary bishop to Raetia, among first patrons of Passau, and later hermit in Zenoburg, near Mais, South Tyrol, Italy, where he died in 475 (January 7); a 5th-century priest and hermit (July 4); a Spanish hermit who died c. 715 (October 25); Valentine Berrio Ochoa, martyred in 1861 (November 24); and Valentine Jaunzarás Gómez, martyred in 1936 (September 18).

A common hagiography describes Saint Valentine as a priest of Rome or as the former Bishop of Terni, an important town of Umbria, in central Italy.

[31] The Legenda Aurea of Jacobus de Voragine, compiled c. 1260 and one of the most-read books of the High Middle Ages, gives sufficient details of the saints for each day of the liturgical year to inspire a homily on each occasion.

The very brief vita of St Valentine states that he was executed for refusing to deny Christ by the order of the "Emperor Claudius" in the year 269.

Alongside a woodcut portrait of Valentine, the text states that he was a Roman priest of exceptional learning who converted the daughter of Asterius and forty-nine others to Christianity before being martyred during the reign of Claudius Gothicus.

One is that the priest Valentine defied the order of the emperor and secretly performed Christian weddings for couples, allowing the husbands involved to escape conscription into the Roman army.

A later Passio repeated the legend and added the adornment that Pope Julius I (357–352) had built the ancient basilica S. Valentini extra Portam on top of his sepulchre, in the Via Flaminia.

[41] The Church of England had him in its pre-Reformation calendars, and restored his mention as bishop and martyr in its 1661–62 Book of Common Prayer, and most provinces of the Anglican Communion celebrate his feast.

His commemoration was still in the 1962 Roman Missal and is thus observed also by those who, in the circumstances indicated in Pope Benedict XVI's 2007 motu proprio Summorum Pontificum, use that edition.

[46] Many of the current legends that characterize Saint Valentine were invented in the 14th century in England, notably by Geoffrey Chaucer and his circle, when the feast day of February 14 first became associated with romantic love.

They were a present from the Pope to King Carlos IV, who entrusted them to the Order of Poor Clerics Regular of the Mother of God of the Pious Schools (Piarists).

On 27 December 1835, the Very Reverend Father John Spratt, Master of Sacred Theology to the Carmelite order in Dublin, was sent the partial remains of St Valentine by Cardinal Carlo Odescalchi, under the auspices of Pope Gregory XVI.

[50] The remains, which include "a small vessel tinged with his blood", were sent as a token of esteem following an eloquent sermon Fr Spratt had delivered in Rome.

[55] A silver reliquary containing a fragment of St. Valentine's skull is found in the parish church of St. Mary's Assumption in Chełmno, Poland.

[59] Alleged relics of St. Valentine also lie at the reliquary of Roquemaure, Gard, France, in the St. Stephen's Cathedral, Vienna, in Balzan in Malta and also in Blessed John Duns Scotus Church in the Gorbals area of Glasgow, Scotland.
