Michael Ducas, a Byzantine historian of the 15th century. He was a descendant of the family of the emperor Michael VII. (Ducas), and held a high position at the court of Con-stantine Palaeologus, the last emperor of Constantinople. After the conquest of that city by Mohammed II. he took refuge with the prince of Lesbos, Dorino Gateluzzi, and by him and his successors was employed in diplomatic missions. He accompanied Domenico Gateluzzi, Dorino's son, to Constantinople, and his prudence and skill saved the independence of Lesbos. But under Nicholas Gateluzzi, the son of Nicholas, the wrath of Mohammed was called down upon the island, and it was united in 1462 to the Ottoman empire. Though Ducas survived this event, nothing more is known of his life. It is probable that he retired to Italy, and wrote in his old age the history which has come down to us. This work begins with an outline of universal chronology, and does not become detailed and truly instructive till the reign of John Palaeologus I., and it terminates in the middle of a sentence at the capture of Lesbos in 14G2. It is written in a barbarous style, but is judicious and impartial.
It was printed at Paris in 1649, and translated into French by the president Cousin, and published in his history of Constantinople (Paris, 1672-'4), and reprinted in Holland in 1685. It was edited by Bekker at Bonn in 1834.
