Narmer Palette
Proto-hieroglyphic symbol systems developed in the second half of the 4th millennium BC, such as the clay labels of a Predynastic ruler called "Scorpion I" (Naqada IIIA period, c. 33rd century BC) recovered at Abydos (modern Umm el-Qa'ab) in 1998 or the Narmer Palette (c. 31st century BC).
