In Greek mythology, Amykos (Ancient Greek: Ἄμυκος), Latinized as Amycus, was the king of the Bebryces, a mythical people in Bithynia.
Amycus was the son of Poseidon and the Bithynian nymph Melia.[1]
Amycus was a doughty man but being a king he compelled strangers to box as a way of killing them.[2] When the Argonauts passed through Bithynia, Amycus challenged the best man of the crew to a boxing match. Polydeuces undertook to box against him and killed him with a blow on the elbow.[3]
When the Bebryces rush to avenge him, the chiefs snatched up their arms and put them to flight with great slaughter.
During ancient time the bay at modern Beykoz was called Amykos.[4]
