Saint Hermes, born in Greece, died in Rome as a martyr in 120, is venerated as a saint by the Catholic Church and the Eastern Orthodox Church. His name appears in the Martyrologium Hieronymianum as well as entries in the Depositio Martyrum. There was a large basilica over his tomb that was built around 600 by Pope Pelagius I and restored by Pope Adrian I. A catacomb in the Salarian Way bears his name.
In the Roman Rite, his feast is on 28 August. Under that date, he appears in the Roman Martyrology, the official but professedly incomplete list of saints recognized by the Catholic Church. The entry is as follows: "In the Cemetery of Basilia on the Old Salarian Way, Saint Hermes, Martyr, whom, as reported by Saint Damasus, Greece sent forth, but Rome kept as its citizen when he died for the holy name."
His existence is attested by his early cult. However, his Acts, included in those of Pope Alexander I, are legendary. They depict Hermes as a wealthy freedman who with his companions was martyred in Rome, being killed on the orders of a judge named Aurelian.
