Eutyches
Eutyches, an ecclesiastic of the 5th century, was the superior of a monastery near Constantinople. He was at first inclined to the Nestorian heresy that Christ possessed two distinct natures, but afterwards adopted a modification of the Monophysite heresy, and for this he was excommunicated by the Council of Constantinople in 448. He was afterwards restored, to be again condemned, together with the Nestorians, by the Council of Chalcedon in 451. From that time he disappears from history, but his views were continued by a sect which bore his name.
