Diodorus Siculus was a Sicilian Greek historian who lived from 90 to 21 BC.
He wrote, a world history in 40 books, ending it near the time of his death with Caesar's Gallic Wars. Fully preserved are Books I-V and XI-XX, which cover Egyptian, Mesopotamian, Indian, Scythian, Arabian, and North African history and parts of Greek and Roman history.
His histories, while not considered great scholarly material in their own right, borrowed heavily from other writers whose works are now lost. In this regard, Siculus is valuable as a historical record for those writers who came before him.
Works: Bibliotheca Historica =Library of History, surviving books cover the ancient Egyptian, Assyrians, Ethiopians and Greeks up to about 302 BC.

“Along with lavish display of every sort, Philip included in the procession statues of the twelve Gods wrought with great artistry and adorned with a dazzling show of wealth to strike awe to the beholder, and along with these was conducted a thirteenth statue, suitable for a god, that of Philip himself, so that the king exhibited himself enthroned among the twelve Gods. Every seat in the theater was taken when Philip appeared wearing a white cloak and by his express orders his bodyguard held away from him and followed only at a distance, since he wanted to show publicly that he was protected by the goodwill of all the Hellenes, and had no need of a guard of spearmen.”

“He [Demosthenes] was generally believed to have received large sums of money from that source [King of Persian] in payment for his efforts to check the Macedonians and indeed Aeschines is said to have referred to this in a speech when he taunted Demosthenes with his venality:At the moment, it is true, his extravagance has been glutted by the king’s gold, but even this will not satisfy him; no wealth has ever proved sufficient for a greedy character””
