Saint Jacob of Nisibis (, ; Greek: Ἅγιος Ἰάκωβος Ἐπίσκοπος Μυγδονίας; Armenian: Յակոբ Մծբնայ, ), also known as Saint Jacob of Mygdonia, Saint Jacob the Great, and Saint James of Nisibis, was the Bishop of Nisibis until his death. He was lauded as the "Moses of Mesopotamia", and was the spiritual father of the renowned writer and theologian Saint Ephrem the Syrian. Saint Jacob was present at the first ecumenical council at Nicaea, and is venerated as a saint by the Church of the East, Eastern Orthodox Church, Oriental Orthodox Church, Roman Catholic Church, and Eastern Catholic Churches. Biography Saint Jacob was the son of prince Gefal, and was born in the city of Nisibis in Mesopotamia in the 3rd century AD. It is claimed that he was a relative of Saint Gregory the Illuminator. Saint Jacob became a Confessor of the Faith for his suffering during persecution by Emperor Maximian. Saint Jacob became an anchorite in c. 280 in the mountains near Nisibis where, according to Saint Theodoret of Cyrrhus, he survived on herbs and fruits, and chose to wear no clothes, build shelter, or light fires for warmth. The saint became famous, and received visits from Sheria, Bishop of Arbela (r. 304–316), according to the Chronicle of Arbela. The saint resolved to climb Mount Qardu, traditionally believed to be the resting place of Noah's Ark, and recover a fragment of the ark upon hearing from the hermit Maroukeh that local people doubted the Great Flood. Saint Jacob ascended the mountain and rested close to the summit; in his sleep, an angel placed a fragment of the ark close to him, and instructed him to awake. The saint brought the relic to the hermit Maroukeh and, according to the saint's hagiography, a sacred spring appeared where the saint had rested, reputed to have healing properties. A number of miracles are credited to Saint Jacob by Saint Theodoret in Historia Religiosa (Religious History), in which the saint had a boulder explode beside a Persian judge who had given an unjust judgement. Also, in one incident, Saint Jacob cursed boastful, promiscuous women by a spring so that their hair became white, and the spring disappeared. The women subsequently repented, and the spring returned, however, the women's hair remained white. As well as this, a group of people attempted to deceive the saint whereby they asked for money to fund the burial
