Diodorus Siculus (Greek: ), was a Greek historian who flourished in the 1st century BC. According to Diodorus own work he was born at Agyrium in Sicily (now called Agira). With but one exception, antiquity affords no further information about Diodorus’ life and doing, than is to be found in his own work, Bibliotheca historica. Only Jerome, in his Chronicon under the year of Abraham 1968 (49 BC) writes "Diodorus of Sicily, a writer of Greek history, became illustrious". His English translator, Charles Henry Oldfather, remarks on the "striking coincidence" that one of only two known Greek inscriptions from Agyrium (I.G. XIV, 588) is the tombstone of one "Diodorus, the son of Apollonius".
