Although the despotic character of his measures is contrary to modern sensibilities, he was indeed a "nursing father" of the Church. Both the "Codex" and the "Novellae" contain many enactments regarding donations, foundations, and the administration of ecclesiastical property; election and rights of bishops, priests and abbots; monastic life, residential obligations of the clergy, conduct of divine service, episcopal jurisdiction, etc. Justinian also rebuilt the Church of Hagia Sophia (which cost 20,000 pounds of gold), the original site having been destroyed during the Nika riots. The new Hagia Sophia, with its numerous chapels and shrines, gilded octagonal dome, and mosaics, became the centre and most visible monument of Eastern Orthodoxy in Constantinople.
