Pasion

Pasion (Ancient Greek: Πασίων; before 430 – 370 BC) (alternatively spelt Pasio ) was a slave in Ancient Greece from the 4th century BC, who rose to become a successful banker and Athenian citizen.

Pasion was born some time before 430 BC. He was owned by the bankers Antisthenes and Archestratus, who had a bank at the Piraeus, the harbor five miles out of Athens. During his slavery, he quickly rose to chief clerk (Argyramoibos) in charge of a money-changing table at the port, and proved so valuable that by 394 BC he had been manumitted as reward for his faithful service.
