The earliest writing can be traced to Sumer, in Mesopotamia. This system did not use an alphabet, instead it used pictographs which are symbols representing familiar objects. This type of writing was called cuneiform, or wedge-shaped writing. Egyptians used hieroglyphics, also a pictograph system.
The cuneiform writing dates between the 3rd millennium and 2nd century BC. It could be categorized as: (1) Sumerian cuneiform, (2) Babylonian cuneiform and (3) Assyrian cuneiform. The hieroglyphics, and the language and religion of ancient Egypt. Egyptians borrowed the idea of pictorial writing from Sumerians. Their writing, which was introduced in 3000 BC, was called hieroglyphics and was styled as pictography or ideograms. It had about 700 signs and was written mainly from right to left but occasionally from left to right or top to downward.
