sentences:  Herodotus was almost certainly referring to Kassites when he described "Ethiopians [from] above Egypt" in the Persian army that invaded Greece in 492 BC.Herodotus was presumably repeating an account that had used the name "Kush" (Cush), or something similar, to describe the Kassites; "Kush" was also, purely by coincidence, a name for Ethiopia.A similar confusion of Kassites with Ethiopians is evident in various ancient Greek accounts of the Trojan war hero Memnon, who was sometimes described as a "Kissian" and founder of Susa, and other times as Ethiopian.
