Nitocris_of_Babylon
Nitocris of Babylon (c. 550 BC) is an otherwise unknown queen regnant[1] of Babylon described by Herodotus in his Histories. According to Histories of Herodotus, among sovereigns of Babylon two were women, Semiramis and Nitocris.[2] Nitocris is credited by Herodotus with various building projects in Babylon. She is also said to have tricked Darius I by placing her tomb above a gate so that no Persian could pass below and enter through. According to the account, Darius was lured in by a mysterious inscription that served as a trap for greedy kings.[3][4] According to Herodotus she was the wife of Nabonidus (Gr. Labynetus) against whose son an expedition was launched by Cyrus the Great.[5][6] Dougherty and Beaulieu identify the son as Belshazzar.[7]
If this is the case, she is most likely the queen in the story of Belshazzar's feast, and she is identified as such in Handel's oratorio Belshazzar.
