THIRD COUNCIL OF EPHESUS (476)
After the death of Emperor Leo I (457-474), his two successors, Basilicus the Usurper (474-475) and Zeno (474-475, 476-491), intervened in the conflict between the supporters and the opponents of the Council of Chalcedon. In 468, an anti-Chalcedonian delegation of Egyptian monks and clergy sought to recall Timothy Aelurus, Bishop of Alexandria, who had been banished to Cherson. The attempt was successful and Timothy regained his seat after 16 years of exile.
A large number of bishops assembled in 476 in order to reverse the decisions of the Council of Chalcedon. The Coptic Church considers it a meeting rather than an ecumenical council. Several recommendations were addressed to the Emperor Basilicus but the restoration of Zeno in 476 prevented the application. Timothy returned to Alexandria, where he died in 477.
