Homer

“ Ulysses answered, "Achilles, son of Peleus, mightiest of all the Achaeans, in battle you are better than I, and that more than a little, but in counsel I am much before you, for I am older and of greater knowledge. Therefore be patient under my words. Fighting is a thing of which men soon surfeit, and when Jove, who is wars steward, weighs the upshot, it may well prove that the straw which our sickles have reaped is far heavier than the grain. It may not be that the Achaeans should mourn the dead with their bellies; day by day men fall thick and threefold continually ”

“ Let us mourn our dead for a day and bury them out of sight and mind, but let those of us who are left eat and drink that we may arm and fight our foes more fiercely. In that hour let no man hold back, waiting for a second summons; such summons shall bode ill for him who is found lagging behind at our ships; let us rather sally as one man and loose the fury of war upon the Trojans."
When he had thus spoken he took with him the sons of Nestor, with Meges son of Phyleus, Thoas, Meriones, Lycomedes son of Creontes, and Melanippus, and went to the tent of Agamemnon son of Atreus. ”

“ Then Ulysses said, "Achilles, godlike and brave, send not the Achaeans thus against Ilius to fight the Trojans fasting, for the battle will be no brief one, when it is once begun, and heaven has filled both sides with fury; bid them first take food both bread and wine by the ships, for in this there is strength and stay. No man can do battle the livelong day to the going down of the sun if he is without food; however much he may want to fight his strength will fail him before he knows it ”

“ Then Achilles made trial of himself in his armour to see whether it fitted him, so that his limbs could play freely under it, and it seemed to buoy him up as though it had been wings.
He also drew his father's spear out of the spear-stand, a spear so great and heavy and strong that none of the Achaeans save only Achilles had strength to wield it; this was the spear of Pelian ash from the topmost ridges of Mt. Pelion, which Chiron had once given to Peleus, fraught with the death of heroes. Automedon and Alcimus busied themselves with the harnessing of his horses ”

“ Then, as soon as he had satisfied himself with looking at it, he said to his mother, "Mother, the god has given me armour, meet handiwork for an immortal and such as no living could have fashioned; I will now arm, but I much fear that flies will settle upon the son of Menoetius and breed worms about his wounds, so that his body, now he is dead, will be disfigured and the flesh will rot." ”

“ Then said Achilles, "Son of Atreus, king of men Agamemnon, see to these matters at some other season, when there is breathing time and when I am calmer. Would you have men eat while the bodies of those whom Hector son of Priam slew are still lying mangled upon the plain? Let the sons of the Achaeans, say I, fight fasting and without food, till we have avenged them ”

“ On this he sent the other princes away, save only the two sons of Atreus and Ulysses, Nestor, Idomeneus, and the knight Phoenix, who stayed behind and tried to comfort him in the bitterness of his sorrow: but he would not be comforted till he should have flung himself into the jaws of battle, and he fetched sigh on sigh, thinking ever of Patroclus. ”

“ The son of Atreus had not else stirred me to so fierce an anger, nor so stubbornly taken Briseis from me against my will. Surely Jove must have counselled the destruction of many an Argive. Go, now, and take your food that we may begin fighting."
On this he broke up the assembly, and every man went back to his own ship. The Myrmidons attended to the presents and took them away to the ship of Achilles. They placed them in his tents, while the stable-men drove the horses in among the others. ”

“ But a man can fight all day if he is full fed with meat and wine; his heart beats high, and his strength will stay till he has routed all his foes; therefore, send the people away and bid them prepare their meal ”
