The Iliad by Homer Book 14 Page 31

Ajax son of Telamon was more angry than any, for the man had fallen close beside him; so he aimed at Polydamas as he was retreating, but Polydamas saved himself by swerving aside and the spear struck Archelochus son of Antenor, for heaven counselled his destruction; it struck him where the head springs from the neck at the top joint of the spine, and severed both the tendons at the back of the head. His head, mouth, and nostrils reached the ground long before his legs and knees could do so, and Ajax shouted to Polydamas saying, “Think, Polydamas, and tell me truly whether this man is not as well worth killing as Prothoenor was: he seems rich, and of rich family, a brother, it may be, or son of the knight Antenor, for he is very like him.”

But he knew well who it was, and the Trojans were greatly angered.
