Eutyches, a monk of Constantinople, an extreme opponent of Nestorius and of the Antiochene school, and as such supported by the patriarch of Alexandria, Dioscorus, was condemned in the Council of Chalcedon in 451. The Monophysite heresy, which he started, continued to trouble the peace of the Eastern Church and Empire for two centuries. It pervaded Alexandria and even Antioch, under such worthy prelates as Timothy "the Cat" (Alexandrin.) and Peter "the Fuller" (Antiochen.)
