Nikon of the Black Mountain
Nikon of the Black Mountain (born 1025, died 1105) was a Byzantine soldier, monk and author. Born at Constantinople around 1025 to a family of "archontes", Nikon served in the army under Constantine IX (). He never received a formal education and considered himself "simple, uncultivated and completely ignorant". Acting on a vision of the Virgin Mary, he retired to a monastery on the Black Mountain founded by Luke, the former metropolitan of Anazarbos, who also tonsured him. After the death of Luke, Nikon incurred the displeasure of his brother monks by striving to enforce rigid  discipline. He was eventually forced to leave. He tried to establish his own monastery, but ultimately settled in the monastery of Simeon Stylites the Younger on the Wondrous Mountain. In 1084, the Sultanate of Rum conquered Antioch. Nikon moved to the monastery of the "Theotokos tou Roidiou" (Virgin of the Pomegranate) for safety. There he died between 1100 and 1110. Nikon produced two major compilations of ecclesiastical texts: the "Pandektai", a collection of conciliar and patristic writings on canon law for wandering monks, and the "Taktikon", a collection of forty chapters of authoritative texts on liturgical problems. The latter included  a "typikon" initially intended for the community he founded, but they rejected it and the community disbanded. The "typikon" was taken up by the monastery of the Virgin of the Pomegranate.|1991 From the 13th century, the "Taktikon" was the main authority in Russian monasticism. The "Pandektai" was written while he was still on the Black Mountain. Both his works were early translated into Arabic and Slavonic. The Arabic translation, entitled "al-Ḥāwī al-kabīr", was then translated into Ethiopic under the title "Maṣḥafa Ḥāwi" in the 16th century.
