Antiochus of Syracuse (Greek: Ἀντίοχος ὁ Συρακούσιος) was a Greek historian of Magna Graecia, who flourished around 420 BC.^[1] Little is known of Antiochus' life, but his works, of which only fragments remain, enjoyed a high reputation because of their accuracy. He wrote a History of Sicily from the earliest times to 424 BC, which was used by Thucydides, and the Colonizing of Italy, frequently referred to by Strabo and Dionysius of Halicarnassus.^[1] He is one of the authors (= FGrHist 555) whose fragments were collected in Felix Jacoby's Fragmente der griechischen Historiker.
