This book concludes the theme of Akhilleus' withdrawal from the battle and begins that of his revenge on the slayer of his best friend, preparing the way for his confrontation with Hektor. In an agony of grief at the loss of Patroklos, Akhilleus determines to seek revenge despite his mother's warning that it must quickly be followed by his own death. With Athene's assistance, he terrifies the Trojans (though he is now without armour), and the body of Patroklos is carried home. Before the first lament and the preparation of the corpse, the poet turns to Hektor, interweaving a scene which reinforces his over-confidence and his refusal to listen to good advice and withdraw from Akhilleus' fury. After the scene of mourning around Patroklos there is a short conversation between Zeus and Here, marking the end of Zeus's aid to the Trojans and foreshadowing their doom. Meanwhile, Thetis has journeyed to Hephaistos' home on Olumpos, and after affable greetings and a rehearsal of Thetis' sorrows the smith-god sets to work and makes a replacement set of armour, depicting on the great shield the mainly pleasant routines of everyday human life.
