NICEPHORUS (Blemmidas), a priest and monk of Mount Athos, flourished in the 13th century. He refused the patriarchate of Constantinople, being favourable to the Latin church, and more inclined to peace than any of the Greeks of his time. In this spirit he composed two treatises concerning The Profession of the Holy Ghost: one addressed to James patriarch of Bulgaria, and the other to the emperor Theodore Lascaris. In both these he refutes those who maintain, that one cannot say the Holy Ghost proceeds from the Father and the Son. These two tracts are printed in Greek and Latin by Allatius, who has also given us a letter written by Blemmidas on his expelling from the church of her convent Marchesinos, mistress of the emperor John Ducas. There are several other pieces of our author in the Vatican library.
