Diodorus Siculus or Diodorus of Sicily was a Greek historian. He is known for writing the universal history "Bibliotheca historica", much of which survives, between 60 and 30 BC. It is arranged in three parts. The first part covers mythic history up to the destruction of Troy. It is arranged geographically, describing regions around the world including Egypt, India, Arabia, Greece and Europe. The second part covers the Trojan War to the death of Alexander the Great. The third part covers the period to about 60 BC. The title Bibliotheca, meaning 'library', shows that he was using the work of many other authors.
