DONO, PATRIARCA DI *ANTIOCHIA*

DONO, patriarch of *Antioch*. - He was the nephew of Patriarch John, whom he succeeded in 441–42 in the see of Antioch. He was educated in a monastery near Jerusalem under the guidance of St. Euthymius. Upon being elected bishop, he distinguished himself for his firm orthodoxy, but at the same time revealed little understanding and prudence. He was the first to expose the Monophysite error of Eutyches in a rather strong letter to Emperor Theodosius, but then little by little he allowed himself to be swept along by the heretical current led by Dioscorus. In the so-called *Latrocinium* of Ephesus in 449, he even went so far as to subscribe to the rehabilitation of Eutyches and the deposition of Eusebius of Dorylaeum and Flavian of Constantinople, as well as some of his own suffragan bishops, all champions of orthodoxy. Soon afterward, however, he himself was deposed, and withdrawing to his monastery, he died there obscurely.
