[2] In her inscriptions, Adad-guppi claimed that Nabonidus was of the dynastic line of Ashurbanipal (r. 669–631 BC), king of the Neo-Assyrian Empire.
[3] Michael B. Dick opposed Dalley's conviction in 2004, pointing out that even though Nabonidus did go to some length to revive some old Assyrian symbols (such as wearing a wrapped cloak in his depictions, absent in those of other Neo-Babylonian kings but present in Assyrian art) and attempted to link himself to the Sargonid dynasty, there is "no evidence whatsoever that Nabonidus was related to the Sargonid dynasty".
[7] Addagoppe's prediction that Sin would make her son king so that he could restore Harran seems to have been a major influence on Nabonidus, to the cost of his relationship with the priests of Babylon and their traditional gods, particularly Marduk.
Other sources beyond Addagoppe's biography reveal that Nabonidus paid homage to Sîn during his reign as king of Babylon.
Because Addagoppe was buried with the honors of a queen, some scholars have suggested that she acted as a regent for Nabonidus when he abandoned Babylon and moved to the oasis of Teima starting in 552 BC.
