 While the sixth poem refers to Assyria, it is uncertain whether it is an historical reference to ancient Ninevah, or a prophecy, which some religious commentators consider refers to the Seleucid kingdom of Syria, which also took the name Assyria.The seventh is also ambiguous, and may either be a reference to the Sea Peoples, or, again in the view of some religious commentators, to the conquest of Persia by Alexander the Great.In the view of some schools of textual criticism the narrative, excepting the episode involving the donkey, is simply a framework invented in order to be able to insert much older poems.
