The name of two Greek heroes in the Trojan war, and the synonym of a fiery and impetuous warrior: Ajax, the son of Telamon of Sparta, one of the bravest of the Greeks, who, on the death of Achilles, contended with Ulysses for his arms, but was defeated, in consequence of which he lost his reason and put an end to his life; and Ajax, the son of Oileus, swift of foot, like Achilles, who suffered shipwreck on his homeward voyage, as a judgment for an outrage he perpetrated on the person of Cassandra in the temple of Athena in Troy.
