Analysis of information sources in references of the Wikipedia article "Nitocris of Babylon" in English language version.
Herodotus (i. 185) ascribes these works to Nitocris, whom he clearly regards as a queen regnant, and whom he makes the mother of "Labynētos" (i. e., Nabonadius) the last king of Babylon (i. 188).
He appears to have belonged, like Neriglissar, to the priestly order; and it has been conjectured that he was married to Nitocris, a daughter of Nebuchadnezzar, and that she was queen regnant. This conjecture, if admitted, would confirm the statement of Herodotus that many of the defensive works at Babylon, especially designed to repel the Medes, were the work of a queen named Nitocris. It is certain that some of these were constructed during the reign of Nabonadius. If we may assume that his queen was a daughter of the great Nebuchadnezzar, and co-sovereign with her husband, it would be quite natural that tradition should give her the credit for these constructions.
