Library of History, Volume I

Diodorus Siculus, a Greek historian from Agyrium in Sicily, around 80–20 BCE, authored forty books of world history known as Library of History. This work is divided into three parts: mythical history of both non-Greek and Greek peoples up to the Trojan War; history until Alexander's death in 323 BCE; and history up to 54 BCE.

We have complete Books I–V, which cover the Egyptians, Assyrians, Ethiopians, and Greeks, as well as Books XI–XX, detailing Greek history from 480–302 BCE. Additionally, there are fragments of the remaining books. Although Diodorus was an uncritical compiler, he utilised high-quality sources and faithfully reproduced them. His work is invaluable for details that are not recorded elsewhere and serves as evidence for works now lost, especially those of Ephorus, Apollodorus, Agatharchides, Philistus, and Timaeus.

The Loeb Classical Library edition of Library of History by Diodorus Siculus is available in twelve volumes.
