For the story of Sardanapalus, which had excited his interest as a schoolboy, Byron consulted the pages of Diodorus Siculus (_Bibliothecæ Historicæ_, lib. ii. pp. 78, sq., ed. 1604), and, possibly to ward off and neutralize the distracting influence of Shakespeare and other barbarian dramatists, he "turned over" the tragedies of Seneca (_Letters_, 1901, v. 173). It is hardly necessary to remind the modern reader that the Sardanapalus of history is an unverified if not an unverifiable personage. Diodorus the Sicilian, who was contemporary with Cicero, derived his knowledge of Assyrian history from the _Persica_ of Ctesias of Cnidos, who was private physician at the court of Artaxerxes Mnemon (B.C. 405-359), and is said to have had access to, and to have consulted, the "Persian authorities" (διφθέραι Βασιλικαὶ [diphthe/rai Basilikai\]). The character which Ctesias depicted or invented, an effeminate debauchee, sunk in luxury and sloth, who at the last was driven to take up arms, and, after a prolonged but ineffectual resistance, avoided capture by suicide, cannot be identified. Asurbanipal (Ašur-bāni-apli), the son of Esarhaddon and grandson of Sennacherib, who ascended the throne B.C. 668, and reigned for about forty years, was, as the cuneiform records and the friezes of his palace testify, a bold hunter and a mighty warrior. He vanquished Tarkū (Tirhakah) of Ethiopia, and his successor, Urdamanē. Ba'al King of Tyre, Yakinlū King of the island-city of Arvad, Sandăsarmū of Cilicia, Teumman of Elam, and other potentates, suffered defeat at his hands. "The land of Elam," writes the king or his "Historiographer Royal," "through its extent I covered as when a mighty storm approaches; I cut off the head of Teumman, their king... Beyond number I slew his warriors; alive in my hands I took his fighting men; with their corpses, as with thorns and thistles, I filled the vicinity of Susa; their blood I caused to flow in the Eulæus, and I stained its waters like wool." Clearly the Sardanapalus who painted his face and carded purple wool in the _penetralia_ of his seraglio does not bear even a traditional resemblance to Ašur-bāni-apli the Conqueror. All that can be affirmed with any certainty is that within twenty years of the death of Asurbanipal, the Assyrian Empire passed into the hands of the Medes;[1] but there is nothing to show whether the period of decay had already set in before the close of his reign, or under which of his two successors, Ăsur-etil-ilāni or Sin-šar-iškun, the final catastrophe (B.C. 606) took place (_Encyclopedia Biblica_, art. "Assyria," art. "Ăsur-bani-pal," by Leonard W. King).
