HORMISDAS (d. 523), pope from 514 to 523, was a native of Campania. He obtained the reunion of the Eastern and West ern Churches, which had been separated since the excommunica tion of Acacius in 484. After two unsuccessful attempts under the emperor Anastasius I., Hormisdas was able to come to an under standing in 518 with his successor Justin. Legates were despatched to Constantinople ; the memorial of the schismatic patriarchs was condemned ; and union was resumed with the Holy See. Hormis das secured Dionysius Exiguus to translate the Apostolic Canons and also renewed the Gelesian decretum. His memorials and briefs are printed in Migne's Patrol. Lat. vol. 63, in Corpus script. eccl. Vindobon., vol. xxxv., and in A. Thiel, Epistolae Rom. Pont. i.
