Michael Critobulus

Michael Critobulus (; c. 1410 – c. 1470) was a Greek politician, scholar and historian. He is known as the author of a history of the Ottoman conquest of the Eastern Roman Empire under Sultan Mehmet II. Critobulus' work, along with the writings of Doukas, Laonicus Chalcondyles and George Sphrantzes, is one of the principal sources for the Fall of Constantinople in 1453.

Critobulus is a Romanization of the name, which is alternatively transliterated as Kritoboulos, Kritovoulos, Critoboulos; sometimes with Critobulus' provenance affixed (e.g. ''Critobulus of Imbros''). Provided by Wikipedia
