How does Homer make the supplication scene of Iliad XXIV emotive?

Homer makes the supplication scene of Iliad XXIV by introducing Priam with his standard epithets, "King Priam" of the "wide-reaching kingdom", to highlight the contrast with the reality of Priam in his current state. Homer labours the point that Priam has now lost everything, from his kingdom to his children, which forces him to supplicate himself to Achilles that he may give back the body of Hector.
Supplication is a common ancient motif which involves someone who has fallen from grace begging for mercy at the feet of another. In this scene, Priam "touches Achilles by his knees" and "holding his man-slaying hands" whilst begging for his son to be given back to him. Here we have the emotive physical connection between the hands which killed Hector and Hector's own father. This is enough to stir the hearts of any listener, as parenthood is a transcendental human emotion.
Finally, Homer brings the scene to a crescendo as Priam and Achilles break down together in tears and "moans which filled the halls"; the two men are sharing in their mutual familial loss, for Hector and Patroclus respectively. This is an explosive emotional breakdown between two supposed enemies, as they realise that war only brings destruction to loved ones. Homer makes this supplication scene emotive not only by bringing the two great Trojan and Greek enemies together in a mutual share of grief, but by presenting the listener with the ultimate conclusion of the Iliad; that no good truly comes out of war, only sorrow. As war, unfortunately, has been always part of human history, so this scene will always be emotive to its audience.
