Hieronymus of Cardia
Hieronymus of Cardia (Greek: Ἱερώνυμος ὁ Καρδιανός) was a Greek officer, administrator, and historian from Cardia in Thrace, active from the late fourth to the mid-third century BC. He is one of the most important contemporary historians of the Diadochi, and the principal lost source for much of the period between the death of Alexander the Great and the early third century BC.
