Ctesias (Greek: Κ τ η σ ί α ς ), a physician at the Achaemenid royal court in Artaxerxes II era, was also interested in history along with his profession, and was able to gain access to archived data in the Treasury of the Persian Archives, and wrote at least two of his three famous books, Assyrica and Persica. Although the originals of his books have disappeared, the basic themes of his works remained in the writings of other authors after him. These data have received little attention from current academic researchers, and even they were considered an absolute and sometimes relative mythological perspective in most cases. In this paper, the recognition of data, identification of the Assyrian rulers and part of the Medes in the Ctesias' report are reviewed, and finally, a chronology of the data is presented based on the temporal, spatial, field, and identity congruence between Ctesias' and field's data.
