Chrysaphius
Chrysaphius was a eunuch at the Eastern Roman court, who became the chief minister of Theodosius II (r. 408–450). Effectively the ruler of the empire during his ascendancy, he pursued a policy of appeasement towards the Huns, which cost the empire far more gold than any military campaign, while amassing a vast fortune in bribes himself. He is depicted as a sinister figure in all the ancient accounts and is pilloried by Edward Gibbon.
