Ok, the article says it was ‘probably’ a Greek mercenary. They say the helmet was probably from Greece because of the decorations. They say he also had some jewelry with Egyptian goddess Sekhmet and inscription in hieroglyphs talking about Necao I. And the son of Necao I was the first pharaoh that started hiring Greek mercenaries. So it’s possible it was a Greek warrior that fought with Egyptians and later Phoenicians. Interesting life for VI century B.C.
