bishop of Hieropolis, a city of Phrygia, was the disciple of St John the Evangelist, and the companion of Polycarp, as St Jerome observes, and not of John the Ancient, as some other authors have maintained. He composed a work in five books, entitled Expositions of the Discourses of our Lord, of which there are only some fragments now remaining. He it was who introduced the opinion of the Millenarians.
