Two of the Amarna Letters supply a crucial link between Egypt and Assyria: they were written by a king 'Ashur-uballit'. A fundamental assumption of the standard chronology is that they were written by the king of that name recorded in the AKL & Inscriptions. However, Newgrosh lists a series of problems with this identification:
"To Napkhororia Great King, king of Egypt, my brother, thus speaks Ashur-uballit, king of Assyria, Great King, your brother: may well-being reign over you, your house and your land!"
