Composed in 1463 / 1464 in classical Greek, the ten books of the Apodeixeis historiōn cover the period from 1298 to 1463. They mainly depict the rise of the Ottomans from the establishment in Asia Minor to the fall of Byzantium. Taking Herodotos as model and avoiding all judgemental stance, Laonikos tries to understand the rationale behind the emergence of the Ottoman Empire.
