Geoffrey Sampson stated that Egyptian hieroglyphs "came into existence a little after Sumerian script, and, probably, invented under the influence of the latter", and that it is "probable that the general idea of expressing words of a language in writing was brought to Egypt from Sumerian Mesopotamia". There are many instances of Egypt-Mesopotamia relations at the time of the invention of writing, and standard reconstructions of the development of writing generally place the development of the Sumerian proto-cuneiform script before the development of Egyptian hieroglyphs, with the suggestion the former influenced the latter.
