Classical dating

Ctesias, quoted by Diodorus Siculus and in George Syncellus 's Chronographia, claimed to have access to manuscripts from Babylonian archives, which date the founding of Babylon to 2286 BC, under the reign of its first king, Belus. A similar figure is found in the writings of Berossus, who, according to Pliny, stated that astronomical observations commenced at Babylon 490 years before the Greek era of Phoroneus, indicating 2243 BC. Stephanus of Byzantium wrote that Babylon was built 1002 years before the date given by Hellanicus of Lesbos for the siege of Troy (1229 BC), which would date Babylon's foundation to 2231 BC. All of these dates place Babylon's foundation in the 23rd century BC. However, cuneiform records have not been found to correspond with these classical, post-cuneiform accounts.
