PROCORUS (Prochorus, Πρόχωρος). — One of the seven deacons (Acts 6:5) ordained by the Apostles for the service of the community in Jerusalem (ibid. 6:1-6), third in the list after Stephen and Philip. He is not mentioned elsewhere in the New Testament.
An unverifiable tradition holds that he was ordained bishop of Nicomedia in Bithynia by St. Peter. The *Historia Prochorii Christi discipuli, de vita B. Ioannis Apostoli*, included in the *Magna Bibliotheca Patrum* (I, Cologne 1618, pp. 49-69), is a fabric of legends and errors. The Roman Martyrology commemorates him on April 9 as a martyr at Antioch; the Greeks on July 28. Teodorico da Castel San Pietro
