Herodotus says of the Pharaoh Nitocris: (Book II, 100)" ... the name of the woman who reigned was the same as that of the Babylonian queen, namely Nitocris*. Of her [the Egyptian one] they said that, desiring to take vengeance for her brother, whom the Egyptians had slain when he was their king and then, after having slain him, had given his kingdom to her, desiring I say, to take vengeance for him, she destroyed by craft many of the Egyptians. For she caused to be constructed a very large chamber under ground, and making as though she would [make a] handsel [of] it, but in her mind devising other things, she invited those of the Egyptians whom she knew to have had most part in the murder, and gave a great banquet. Then while they were feasting, she let in the river upon them by a secret conduit of large size. Of her they told no more than this, except that, when this had been accomplished, she threw herself into a room full of [burning] embers, in order that she might escape vengeance."
