Nitocris of Babylon

Nitocris of Babylon (c. 550 BC) is an otherwise unknown queen of Babylon described by Herodotus in his "Histories". According to Herodotus she was the wife of Nabonidus (Gr. "Labynetus") against whose son Cyrus the Great launched an expedition. Dougherty and Beaulieu identify the son as Belshazzar. 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".
She 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.
