FILIPPO di SIDE. - Christian historian of the fifth century, born at Side, in Pamphylia. There he was a disciple of Rodone, and later succeeded Didimo il Cicco in directing the Alexandrian Didaskaleion. At Constantinople he was ordained deacon by s. Giovanni Crisostomo, with whom he had cordial relations, and subsequently priest. He unsuccessfully presented his candidacy for the patriarchal see three times. He refuted the books of Giuliano l'Apostata Contro i Galilei.
Around 430 he published the Storia cristiana, from the creation of the world to his own times, in 36 books and almost 1,000 volumes. Only scant fragments remain, containing inaccuracies that would diminish the value of the work. Socrate (Hist. eccl., VII, 26-27; cf. 29, 35) states that he did not observe chronological order and inserted the most varied descriptions and pieces of information.
