Homer's Iliad Book 15 (translated by Robert Fagles)

The Trojans are driven back across the ditch to where their chariots are parked. Zeus awakens and reproaches Hera, who blames Poseidon for the Greek success. Zeus remembers his promise to Thetis and again plans to help the Trojans. Hera returns to Olympos. When Ares hears that his son Askalaphos has been killed, he is enraged and prepares to enter the battle on the Trojan side; Athene dissuades him by reminding him of Zeus' instructions. Hera sends Iris and Apollo to meet with Zeus. Zeus in turn sends Iris to tell Poseidon to leave the battlefield, and Poseidon reluctantly obeys. Next Zeus directs Apollo to discourage the Achaians and to rejuvenate the wounded Hektor, which Apollo quickly does. With the help of Apollo, the Trojans now regain the upper hand, and again cross the ditch to attack the ships. Still nursing Eurypylos, Patroklos observes the Achaian discomfiture and runs to tell Achilleus. Meanwhile, in balancing speeches, Hektor and Aias urge on their comrades. Finally Hektor is able to grab the prow of one of the ships, and the book ends with the Trojans threatening to burn the vessels.
