Proteas of Macedon

Proteas (Πρωτέας), son of Andronicus and Lanike, was a syntrophos and hetairos of Alexander the Great. He had been sent with 15 ships by Antipater to protect the islands and the Greek mainland against Persian attack. Putting in at Chalcis on Euboea he advanced to Cythnus and then caught the Persian admiral Datames at Siphnos at dawn, capturing 8 of his 10 ships. Proteas came with a penteconter from Macedon to join Alexander at Sidon. Like Hegelochus, who served with the fleet, Proteas soon joined Alexander's expedition and accompanied him by land from at least Egypt. He was a notorious drinking companion of Alexander.
