At I.18.015–021, Achilles gets the grim news: that Patroklos has been killed by Hector, and that the fighting to recover his body, despoiled of the armor of Achilles, is still underway. Immediately, Achilles feels akhos ‘grief’, I.18.22. But the mourning and lamentation that is caused by this grief is aimed not only at Patroklos but also at Achilles in the narrative that follows, I.18.021–073. Within this narrative, Achilles gets to have his own wake, as it were. And the akhos ‘grief’ that is now felt by Achilles will never leave him, even after he unsays his mēnis ‘anger’ later on in Iliad 22. Unlike the goddess Demeter in the Homeric Hymn to Demeter, for whom the akhos ‘grief’ that she felt at verses 40 and 90 will go away at verse 436 as soon as she is reunited with Persephone, the akhos ‘grief’ of Achilles will never go away. As Thetis the lamenting mother of Achilles declares at I.18.061–062, this hero will never again stop ‘grieving’, akhnusthai, I.18.062. From now on, Achilles will be a man of constant sorrow (on precedents for this expression, see H24H 1§54). See the comments on I.09.249–250 and on I.23.046–047.
