There are no known inscriptions of Aššur-uballiṭ II (611–609), a man — likely the son and designated heir of Sîn-šarra-iškun — who declared himself king of Assyria in Ḫarrān. This is hardly a surprise given the short duration of his reign, the limited extent of his sphere of direct influence (the northwestern part of the once-great Assyrian Empire, in particular, the area around the cult center of the moon-god Sîn), and the fact that he had to spend most of his time preparing for battle and fighting against Nabopolassar of Babylon and his Median ally Cyaxares for Assyria's survival as a political entity. Should he have had time to have carried out building activities that were not devoted to strengthening the defenses of his makeshift capital, which seems highly implausible according to the information provided in the Fall of Nineveh Chronicle (see pp. 43–46 of the present volume for a translation), then one would expect that any inscriptions written in his name would have been composed for and deposited/displayed in cities located outside of the Assyrian heartland (the "Aššur-Nineveh-Arbela" triangle), for example, Dūr-Katlimmu, Guzana, and Ḫarrān. Because Aššur-uballiṭ's reign was not only short, but very turbulent, it is highly unlikely that any inscription of his will ever be discovered. For further information about the final days of the Assyrian Empire, see p. 37.
