"'Nitrocris of Babylon"' (circa 550 BC) was a queen of Babylon who was either married to Nebuchadnezzar II or a daughter of this.
It is said she carried on several of Nebuchadnezzar's building projects after his death and was also influential in the reign of later kings of Babylon. Herodotus reports she tricked Darius I by placing her tomb above a gate so that the Persian could not pass below. According to the account, she also left a mysterious inscription that served as a trap for greedy kings.[1][2][3][4]
