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.
The Roman historian Quintus Curtius Rufus claims that in 331 BC Amphoterus was sent from the Palestinian coast to Crete with orders to attack the Persians who were blockading the island.
[2] His contemporary, the Roman historian Arrian, claims that Amphoterus was already stationed in the vicinity of Crete, and was ordered to sail for the Peloponnese coast.
B. Bosworth, Professor of Classics and Ancient History at the University of Western Australia, believes that the conflict between the two accounts reflects different views as to the geographic location of Crete.
As a result, Bosworth argues, both Roman historians are actually referring to the same general area when describing Amphoterus' military activities.
