About Diodorus Siculus
Diodorus Siculus or Diodorus of Sicily was an ancient Greek historian from Sicily. He is known for writing the monumental universal history Bibliotheca historica, in forty books, fifteen of which survive intact, between 60 and 30 BC.
The history is arranged in three parts. The first covers mythic history up to the destruction of Troy, arranged geographically, describing regions around the world from Egypt, India and Arabia to Europe. The second covers the time from the Trojan War to the death of Alexander the Great. The third covers the period to about 60 BC. Bibliotheca, meaning 'library', acknowledges that he was drawing on the work of many other authors.
