A Dictionary of Greek and Roman biography and mythology

(Εὐστράτιος), one of the latest commentators on Aristotle, lived about the beginning of the twelfth century after Christ, under the emperor Alexius Comnenus, as metropolitan of Nicaea. According to a hint in the Commentary to the tenth book of the Ethica Nicomachea (if this part of the Commentary is composed by him), he appears to have also lived at Constantinople, and to have written his commentary in this place. (Comp. ad Arist. Eth. Nic. 10.9.13, p. 472, ed. Zell.) Of his life we know nothing else.
