(), bishop of Chalcedon, an ecclesiastical
writer of uncertain date. He wrote a work against the Manichaeans, in twenty books, Καρὰ Μανιχαίων ἐν βιβλίοιρ κ́. Photius, from whom alone we
learn any thing of the work and its author, describes it as written in a concise and elevated,
yet perspicuous, style. It was addressed to one Achillius (Ἀχιλλιορ), at whose request it was written; and was designed to refute the
so-called Gospel (εν̓αγγέλιον) of the Manichaeans, and
the Γιγάντειορ Βιβλυρ, and the Θησαυροί, works of note among the members of that sect. (Phot.
