From his return to Constantinople, Cantacuzene continues his history and that of the empire, one year beyond the abdication of his son Matthew, A.D. 1357 (l. iv. c. l - 50, p. 705 - 911). Nicephorus Gregoras ends with the synod of Constantinople, in the year 1351 (l. xxii. c. 3, p. 660; the rest, to the conclusion of the xxivth book, p. 717, is all controversy); and his fourteen last books are still Mss. in the king of France's library.
