Saint Lawrence (c. 225 258) (Latin: Laurentius, meaning "laurelled") was one of the seven deacons of ancient Rome who were martyred during the persecution of Roman Emperor Valerian in the year 258. According to lore, among the treasure of the Roman church entrusted to Lawrence for safe-keeping was the Holy Chalice, the cup from which Jesus and the Apostles drank at the Last Supper. Lawrence was able to spirit this away to Huesca with a letter and a supposed inventory, where it lay hidden and unregarded for centuries. When Augustine connects Lawrence with a chalice, it is the chalice of the Mass: "For in that Church, you see, as you have regularly been told, he performed the office of deacon; it was there that he administered the sacred chalice of Christs blood"." According to Christian mythology, the Holy Grail is a relic that was sent by St. Lawrence to his parents in Spain. He entrusted this sacred chalice to a friend whom he knew would travel back to Spain, his home country. While the Holy Chalice's exact journey through the centuries is disputed, it is generally accepted by Catholics that the Chalice was sent by his family to a monastery for preservation and veneration. Historical records indicate that this chalice has been venerated and preserved by a number of monks and monasteries through the ages. Today the Holy Grail is venerated in a special chapel in the Catholic Cathedral of Valencia, Spain, in the region of St Lawrence's birth and early life. By tradition, Lawrence was sentenced at San Lorenzo in Miranda, martyred at San Lorenzo in Panisperna, and buried in the Via Tiburtina in the Catacomb of Cyriaca by Hippolytus and Justinus, a presbyter. Tradition holds that Lawrence was burned or "grilled" to death, hence his association with the gridiron. One of the early sources for the martyrdom of Saint Lawrence was the description by Aurelius Prudentius Clemens in his Peristephanon, Hymn II. Constantine I is said to have built a small oratory in honour of the martyr, which was a station on the itineraries of the graves of the Roman martyrs by the 7th century. Pope Damasus I rebuilt or repaired the church, now known as San Lorenzo fuori le Mura, while the minor basilica of San Lorenzo in Panisperna was built over the place of his martyrdom. The gridiron of the martyrdom was placed by Pope Paschal II in the church of San Lorenzo in Lucina.
