Diodorus Siculus

Diodorus Siculus (/ˌdaɪəˈdɔːrəs ˈsɪkjʊləs/; Greek: Διόδωρος Σικελιώτης Diodoros Sikeliotes) (fl. 1st century BC) or Diodorus of Sicily was a Greek historian. He is known for writing the monumental universal history Bibliotheca historica, much of which survives, between 60 and 30 BC. It 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 Greece and Europe. The second covers 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.

According to his own work, he was born at Agyrium in Sicily (now called Agira). With one exception, antiquity affords no further information about his life and doings beyond in his work. Only Jerome, in his Chronicon under the "year of Abraham 1968" (49 BC), writes, "Diodorus of Sicily, a writer of Greek history, became illustrious". However, his English translator, Charles Henry Oldfather, remarks on the "striking coincidence" that one of only two known Greek inscriptions from Agyrium (Inscriptiones Graecae XIV, 588) is the tombstone of one "Diodorus, the son of Apollonius".
