Ancient Egyptian Tamehu. The area of Egypt comprising the Nile Delta from the Mediterranean Sea north to Memphis. It appears to have evolved into a separate kingdom, possibly with its capital at Buto, during the Predynastic Period and was united, forcibly or not, with Upper Egypt to form a single country described in Egyptian texts as the Two Lands. The symbol of Lower Egypt was the sedge plant, which formed part of the royal title with the bee of Upper Egypt. The tutelary goddess Wadjet was represented as a serpent, oruraeus, on the royal brow. The royal crown of Lower Egypt, known as the red crown, consisted of a flat top with a vertical section at the back.
