It seems that, despite being literate before anyone else, the ancient civilizations of Egypt and the Fertile Crescent left behind very little in terms of literature compared to the Greco-Romans, Indians, Chinese, etc. We mostly have dry records, some religious texts, manuals, etc. from the pre-hellenistic Mideast, the Old Testament being a remarkable exception in terms of its scope. Or is this an erroneous impression?
