The inscription also refers to the Dacian king Burebista, and one interpretation is that Akornion was his chief adviser (Ancient Greek: πρῶτοσφίλος, literally "first friend") in Dionysopolis. Other sources indicate that Akornion was sent as an ambassador of Burebista to Pompey, to discuss an alliance against Julius Caesar.
