Homer, The Iliad
Samuel Butler, Ed.

Wounded Eurypylos made answer, "Noble Patroklos, there is no hope left for the Achaeans but they will perish at their ships. All they that were princes among us are lying struck down and wounded at the hands of the Trojans, who are waxing stronger and stronger. But save me and take me to your ship; cut out the arrow from my thigh; wash the black blood from off it with warm water, and lay upon it those gracious herbs which, so they say, have been shown you by Achilles, who was himself shown them by Chiron, most righteous of all the centaurs. For of the physicians Podaleirios and Machaon, I hear that the one is lying wounded in his tent and is himself in need of healing, while the other is fighting the Trojans upon the plain."

"Hero Eurypylos," replied the brave son of Menoitios, "how may these things be? What can I do? I am on my way to bear a message to noble Achilles from Nestor of Gerene, bulwark of the Achaeans, but even so I will not be unmindful your distress."

With this he clasped him round the middle and led him into the tent, and a squire [therapôn], when he saw him, spread bullock-skins on the ground for him to lie on. He laid him at full length and cut out the sharp arrow from his thigh; he washed the black blood from the wound with warm water; he then crushed a bitter herb, rubbing it between his hands, and spread it upon the wound; this was a virtuous herb which killed all pain; so the wound presently dried and the blood left off flowing.
