The cuneiform system originated in southern Mesopotamia in the late fourth millennium BCE, where the earliest tablets were found in level IV of the Eanna district of Uruk. Nearly simultaneously with Uruk's development of cuneiform, another script, also making use of clay as the basic medium but having a slightly different inventory of signs, appeared in the neighboring Susiana Plain, and is known as the "proto-Elamite" script. Egyptian hieroglyphics also date from the late fourth millennium BCE, but simple symbolic writing has been found, dating back to around 4000 BCE. This would probably make the Egyptian language the first to be recorded in some written form.
