Nitocris (Greek Νίτωκρις, from Egyptian Neith-iqret, "Neith is excellent"). Herodotus and Manetho name her as the last ruler of the Sixth Dynasty of Old Kingdom Egypt (c. 2184-2181 BCE) — possibly the first female pharaoh in recorded history, predating Sobekneferu and Hatshepsut. According to Herodotus, she avenged her brother-king's murder by inviting his killers to a feast in an underground chamber, then flooding it with the Nile — then committed suicide in a chamber of ashes. Modern scholarship debates whether she is historical or legendary; the Saite-era Nitocris I (c. 656-585 BCE) was a separate God's Wife of Amun.
Featured in Herodotus's Histories and George Henty's The Cat of Bubastes (1888).
Nitocris reduces to five — the number of Old Kingdom queen.
