But Pyrrhus, seeing the stormy sea that surged about him, took off the coronal, with which his helmet was distinguished, and gave it to one of his companions; then, relying on his horse, he plunged in among the enemy who were pursuing him. Here he was wounded by a spear which pierced his breastplate-not a mortal, nor even a severe wound-and turned upon the man who had struck him, who was an Argive, not of illustrious birth, but the son of a poor old woman.
