Amphoterus (Greek: Ἀμφοτερός) the brother of Craterus, was appointed by Alexander the Great to be his commander of the fleet in the Hellespont in 333 BC. Amphoterus' appointment recognized his successful attempts to subdue the islands between Greece and Asia which had not acknowledged Alexander. Amphoterus cleared Crete of the Persians and pirates. He then sailed to the Peloponnese in 331 BC, where he put down an uprising against Macedonian control. Alexander sent Cypriot and Phoenician ships to help Amphoterus.[1]
