Philotheus (Φιλόθεος) (1), an Eastern prelate, flourished as patriarch of Alexandria about A.D. 995. He was a man of luxurious habits and a most scandalous course of life. Philotheus wrote four works, the titles of which, as translated from the Arabic, are, Declarator: — Rara Commentatorum, et Depravationes Haereticorum: — Detectio Arcanorum: — Autobiographia. All of these works are lost, and it does rot appear whether the author wrote in Arabic or in Greek. A sermon, De Mandatis Donmini nostri Jesu Christi (ed. Greek and Latin by P. Possinus in his A scetica), is ascribed to one S. Pilotheus, perhaps the same person. See Cave. Hist. Litt. ad an. 995; Smith, Dict. of Gr. and Rom. Biog. s.v.
