At any rate its remains add nothing to our knowledge of the state of art in Esar-haddon's time, or to our estimate of that monarch's genius as a builder.
After a reign of thirteen years, Esar-haddon, "king of Assyria, Babylon, Egypt, Meroe, and Ethiopia," as he styles himself in his later inscriptions, died, leaving his crown to his eldest son, Asshur-bani-pal, whom he had already associated in the government.
Asshur-bani-pal ascended the throne in B.C.668, or very early in B.C.
667; and his first act seems to have been to appoint as viceroy of Babylon his younger brother Saul-Mugina, who appears as Sam-mughes in Polyhistor, and as Saosduchinus in the Canon of Ptolemy.
The first war in which Asshur-bani-pal engaged was most probably with Egypt.

Late in the reign of Esar-haddon, Tirhakah (as already stated 619) had descended from the upper country, had recovered Thebes, Memphis, and most of the other Egyptian cities, and expelled from them the princes and governors appointed by Esar-haddon upon his conquest.
Asshur-bani-pal, shortly after his accession, collected his forces, and marched through Syria into Egypt, where he defeated the army sent against him by Tirhakah in a great battle near the city of Kar-banit.
Tirhakah, who was at Memphis, hearing of the disaster that had befallen his army, abandoned Lower Egypt, and sailed up the Nile to Thebes, whither the forces of Asshur-bani-pal followed him; but the nimble Ethiopian retreated still further up the Nile valley, leaving all Egypt from Thebes downwards to his adversary.

Asshur-bani-pal, upon this, reinstated in their former governments the various princes and rulers whom his lather had originally appointed, and whom Tirhakah had expelled; and then, having rested and refreshed his army by a short stay in Thebes, returned victoriously by way of Syria to Nineveh.
Scarcely was he departed when intrigues began for the restoration of the Ethiopian power.

Neco and some of the other Egyptian governors, whom Asshur-bani-pal had just reinstated in their posts, deserted the Assyrian side and went over to the Ethiopians.

Attempts were made to suppress the incipient revolt by the governors who continued faithful; Neco and one or two of his copartners in guilt were seized and sent in chains to Assyria; and some of the cities chiefly implicated, as Sais, Mendes, and Tanis (Zoan), were punished.
