The Chronicle of Manetho

Manetho was an Egyptian priest who made a work (all in Greek) over the Egyptian history in the 200s BC. All that is left are transcriptions made by Christian historians like, Africanus (300s AD) and Eusebius (3-400s AD). Copiers' mistakes and only Greek names reduces the historical value.
