What is "manetho"

Manetho (; ) was an Egyptian historian and priest from Sebennytos ( ancient Egyptian: Tjebnutjer) who lived during the Ptolemaic era, approximately during the 3rd century BC.

Manetho wrote the Aegyptiaca (History of Egypt). His work is of great interest to Egyptologists, and is often used as evidence for the chronology of the reigns of pharaohs. The earliest and only surviving reference to Manetho's Aegyptiaca is that of the Jewish historian Josephus in his work Against Apion.
