'ANĀNIŠO (ENANIESU, 'ENĀNIŠO). - Nestorian monk, he studied with his brother Iesuyab at the school of Nisibis, where both had as friend and fellow disciple the namesake Iesuyab, who, like them, was from Adiabene and later became patriarch of the Nestorians. The two brothers embraced the monastic state and entered the monastery of Mount Izla, but later 'A. visited the holy places and from there went to the desert of Nitria, where he studied the deeds of the anchorites. Having returned to his homeland, he moved with his brother to the monastery of Beth 'Abe. 'A., says Thomas of Marga, “surpassed in intelligence and learning all those who preceded him and all those who came after him.” Therefore Iesuyab, first metropolitan of Arbela and then patriarch (647–58), made use of 'A.'s work in compiling the canonical hours. Among his other works, the Liber canonum de aequilitteris is known to us, published by Hoffmann (Opuscula Nestoriana, Kiel 1880, pp. 2–49).
'A. is famous for having produced a good Syriac recension of Palladius’ Historia Lausiaca, at the request of Patriarch George (658–80). This book, widespread among the Nestorians, was edited by Bedjan (Acta mart. et sanct., VII, Leipzig 1897) in four parts, of which the one inserted between the second and third is attributed to St. Jerome, although it is now acknowledged to be the work of Timothy of Alexandria, translated into Latin by Rufinus. Another edition was produced by W. Budge, with an English translation (The Book of Paradise, London 1904).
