Diodorus Siculus

Diodorus Siculus or Diodorus of Sicily (active 1st century BCE) was a Greek historian, known for his universal history Bibliotheca Historica. Originally, it was a 40-volume monumental work, covering the history of the Mediterranean region from mythical times to his own lifetime, around 60/59 BCE. Today 15 books survive complete and others in fragments. He has been accused of being a mere compiler of earlier sources, however, Diodorus' use of these writings also preserved works that may have been lost without him, and in the modern day the Bibliotheca is recognized for its unity of themes.
