The Iliad 15.392–398

But when he saw the Trojans rushing upon the wall, while the Danaans with loud cries turned in flight, then he uttered a groan, and smote his two thighs with the flat of his hands, and with wailing spake, saying: Eurypylus, in no wise may I abide longer with thee here,albeit thy need is sore; for lo, a mighty struggle hath arisen. Nay, as for thee, let thy squire bring thee comfort, but I will hasten to Achilles, that I may urge him on to do battle. Who knows but that, heaven helping, I may rouse his spirit with my persuading? A good thing is the persuasion of a comrade.
