Diodorus Siculus

Diodorus came from Sicily and worked through the first century BC compiling what he called the Bibliotheca historica, a universal history that drew openly on earlier authors. He divided it into three parts: mythic time to the fall of Troy, arranged by geography and sweeping from Egypt and India to Europe; the Trojan War through Alexander's death; and the centuries down to around 60 BC. Forty books in total. Fifteen survive intact. The title Bibliotheca — "library" — was his acknowledgment that he was synthesizing the work of many writers before him, not claiming sole discovery.
