Definition: Diodorus Siculus, whose work was probably written between 60 and 30 B.C., but whose actual dates are unknown, calculated that the history he wrote (Bibliotheke) spanned 1138 years, from before the Trojan War to his own lifetime during the late Roman Republic.
Fifteen of his 40 books on universal history are extant, but only fragments remain of the rest. He has until recently been criticized as having simply recorded what his predecessors had already written.
