a patriarch of Alexandria, flourished early in the 13th century, and was particularly well versed in ecclesiastical law. He proposed certain questions for solution on various points of ecclesiastical law or practice. Sixty-four of these questions, with the answers of Theodorus Balsamon, are given in the Jus Orientale of Bonefidius, p. 237, etc. (Paris, 1573, 8vo), and in the Jus Graeco-Ronmanums of Leunclavius, 1:362-394 (Frankfort, 1596, fol.). Some MSS. contain two questions and solutions more than the printed copies. Fabricius suggests that Mark of Alexandria is the Marcus cited in a MS., Catena in Mastthci Evangelium, of Macarius Chrysocephalus, extant in the Bodleian Library at Oxford. — Cave, Hist.
