3rd-century BC historians

Manetho (; Manéthōn, gen.: Μανέθωνος, fl. 290–260 BCE) was an Egyptian priest of the Ptolemaic Kingdom who lived in the early third century BCE, at the very beginning of the Hellenistic period. Little is certain about his life. He is known today as the author of a history of Egypt in Greek called the Aegyptiaca (History of Egypt), written during the reign of Ptolemy I Soter or Ptolemy II Philadelphus (285–246 BCE). None of Manetho’s original texts have survived; they are lost literary works, known only from fragments transmitted by later authors of classical and late antiquity.
