Recently-discovered inscriptions relating to a variety of early rulers including Queen Neith-Hotep:
QuoteWhile Egyptologists knew that Neith-Hotep existed, they believed she was married to a pharaoh named Narmer. "The inscriptions demonstrate that she [Neith-Hotep] was not the wife of Narmer, but a regent queen at the beginning of the reign of Djer," Tallet said.
