Brief accounts of Shila's reign are given in the Ecclesiastical Chronicle of the Jacobite writer Bar Hebraeus (floruit 1280) and in the ecclesiastical histories of the Nestorian writers Mari (twelfth-century), ʿAmr (fourteenth-century) and Sliba (fourteenth-century).
Modern assessments of his patriarchate can be found in Wigram's Introduction to the History of the Assyrian Church and David Wilmshurst's The Martyred Church.
[1] The following account of Shila's reign is given by Bar Hebraeus: Babai died after five years in office, and his successor was Shila, whose name is derived from the Hebrew word 'question'.
