Diodōrus Siculus, Sicilian Greek historian who wrote between c.60 and 30 BC a world history (Bibliothēkē historikē), centred on Rome, in forty books. Books 1–3 comprise the ancient legends of Asia and North Africa, books 4–6 those of Greece and Europe. All these books are fully preserved except for 6, which is fragmentary. Books 7–17 cover the period from the Trojan War to Alexander the Great; 7–10 survive in fragments, 11–17 are fully preserved. Books 18–40 cover the period from the Diadochoi (successors of Alexander) to Julius Caesar (54 BC); 18–20 are fully preserved, 21–40 survive in fragments. A complete copy is said to have perished in the sack of Constantinople by the Turks in 1453. The work is an uncritical compilation, and confused when Diodorus changes sources, but valuable for preserving the evidence of these sources: for example, his evidence is very important when, for the events in Greece around 400 BC he draws on the history of which Hellenica Oxyrhynchia is a part (see OXYRHYNCUS HISTORIAN). In the early books he is a useful source of mythological information. Concerning the gods his view is somewhat euhemerist (see EUHEMERUS).
