The Babyloniaca (Koine Greek: Βαβυλωνιακά, Babyloniaka, "History of Babylonia") is a history of the Babylonian civilization, written as three books. It was written in Greek during the Hellenistic period around 281 BCE, by the historian and Babylonian priest, Berossus, in dedication to the ascent of Antiochus I Soter to the throne of the Seleucid Empire.
The first book describes the beginning of Babylonian civilization, geography, and cosmology (a version that resembles the cosmology of the famous creation myth Enūma Eliš), and explains the transition of mankind before and after the revelation of divine law. The second book focuses on the genealogy of Babylon, starting with the antediluvian kings down to Nabu-Naṣir in 747 BCE, and presents an account of the Mesopotamian flood myth. The third book covered the recent history of Babylonia from Nabu-Naṣir to Alexander the Great.
