Amycus
Amycus (without bellowing) In Greek mythology, a giant son of Poseidon and Melië, a nymph. Amycus would force everyone who landed on the Bithynian coast to box with him. When the Argonauts wished to draw water from a spring in his country, he forbade them. He was killed in a match with Polydeuces. Ovid’s Metamorphoses (book 12) and Apollonius Rhodius’s Argonautica (book 2) tell the tale.
