Fourth-century Church historian; b. Borissus, Asia Minor, c. 368; d. probably Constantinople, 425 or 433. A layman well read and widely traveled, Philostorgius wrote a church history in 12 books known only through a summary and epitome in photius (Biblioth. Codex 40), and fragments in Suidas, the Martyrion of Artemius by John of Rhodes (ninth century), a Vita Constantini (H. Optiz, Cod. Ang. Gr. 22), and the Thesaurus orthodoxae fidei by Nicetas Acominatus. Philostorgius presented his work as a continuation of the Ecclesiastical History of eusebius of caesarea, and covered the period from 315 to 425. He was, however, obviously an Arian partisan and favored the cause of the neo-Arian heretic Eunomius of Cyzicus. While praising his style and diction, Photius maintained that Philostorgius was frequently inaccurate, particularly when he praised Eunomius, Aëtius of Antioch, and Eusebius of Nicomedia or condemned Acacius of Caesarea in Palestine and Basil of Cappadocia. His history is important for the citation of Arian sources that have not been preserved, for the evidence it offers of the attraction Arianism had for the cultured Greek mind, and for its thesis that the acceptance of the theology of athanasius of alexandria spelled the destruction of the Roman Empire. Philostorgius mentioned an Encomium on Eunomius and a Refutation of Porphyry of his own composition, which have not been preserved.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
