Agamemnon, the leader of the Greeks, robs Achilles of his beautiful captive Briseis, and the invulnerable hero, furious at the insult, retires in sullen rage to his ships, forbids his troops to take part in the war, and sulks in anger while battle after battle is fought. Deprived of his mighty aid, the Greeks find the Trojans quite their match, and the fortunes of the warring hosts vary day by day. On a watch-tower in Troy sits Helen the beautiful, gazing out on the field of conflict, and naming for old Priam, who sits beside her, the Grecian leaders as they appear at the head of their hosts on the plain below. On this plain meet in fierce combat Paris the abductor and Menelaus the indignant husband. Vengeance lends double weight to the spear of the latter, and Paris is so fiercely assailed that Venus has to come to his aid to save him from death. Meanwhile a Trojan archer wounds Menelaus with an arrow, and a general battle ensues. The conflict is a fierce one, and many warriors on both sides are slain. Diomedes, a bold Grecian chieftain, is the hero of the day. Trojans fall by scores before his mighty spear, he rages in fury from side to side of the field, and at length meets the great AEneas, whose thigh he breaks with a huge stone. But AEneas is the son of the goddess Venus, who flies to his aid and bears him from the field. The furious Greek daringly pursues the flying divinity, and even succeeds in wounding the goddess of love with his impious spear. At this sad outcome Venus, to whom physical pain is a new sensation, flies in dismay to Olympus, the home of the deities, and hides her weeping face in the lap of Father Jove, while her lady enemies taunt her with biting sarcasms. The whole scene is an amusing example of the childish folly of mythology. In the next scene a new hero appears upon the field, Hector, the warlike son of Priam, and next to Achilles the greatest warrior of the war. He arms himself inside the walls, and takes an affectionate leave of his wife Andromache and his infant son, the child crying with terror at his glittering helmet and nodding plume. This mild demeanor of the warrior changes to warlike ardor when he appears upon the field. His coming turns the tide of battle. The victorious Greeks are driven back before his shining spear, many of them are slain, and the whole host is driven to its ships and almost forced to take flight by sea from the victorious onset of Hector and his triumphant followers. While the Greeks cower in their ships the Trojans spend the night in bivouac upon the field. Homer gives us a picturesque description of this night-watch, which Tennyson has thus charmingly rendered into English:
