He also had a sister, named Philopatho, who was the mother of the Athenian tragic poet Philocles. Ameinias was from the Attica deme of Pallene according to Herodotus, or of that of Decelea according to Plutarch. He made the first attack upon the Persian ships (according to Athenians his ship made the first attack, but Aeginetans said that one of their ships made the first attack), he also pursued the ship of Artemisia, and she rammed and sunk the ship of Damasithymos who was her ally to escape.
When Ameinias saw that he thought that her ship was Greek and he changed the direction of his Trireme to chase other Persian ships.
Herodotus believed that Ameinias didn"t know that Artemisia was on the ship, because otherwise he would not have ceased his pursuit until either he had captured her or had been captured himself, because orders had been given to the Athenian captains. Moreover, a prize had been offered of ten thousand drachmas for the man who should take her alive, since they thought it intolerable that a woman should lead an expedition against Athens.
In addition, according to Plutarch, he and the Socles of Pallene were the men who killed Ariamenes (Herodotus says that his name was Ariabignes), brother of Xerxes and admiral of the Persian navy. When Ariamenes attempted to board on their ship, they hit him with their spears, and thrust him into the sea.
Ameinias and Eumenes of Anagyrus (Anagyrus is the modern Vari) were judged to have been the bravest on this occasion among all the Athenians.
