Source A: Homer, Iliad 24.559-570
'Then swift-footed Achilles glared at him and said: "Do not provoke me any further, old man. I myself intend to give Hector back to you; a messenger came to me from Zeus - my mother who bore me, the daughter of the Old Man of the Sea. And I know in my heart, Priam, and it does not escape me, that some god led you to the swift ships of the Achaeans; for no mortal would dare to come into the camp, not even a man in his prime, nor could he slip past the guards, or easily push back the bar of our doors. So do not stir my heart any more in its grief, old man, in case I do not spare even you in my hut, suppliant though you are, and so break the commands of Zeus."'
To what extent is Achilles presented as a changed man in Book 24? Use Source A as a starting point and your own knowledge of Books 22 and 24.
Model answer
Source A shows that Achilles has not completely changed. He 'glared at' Priam and warns him not to 'provoke me any further', threatening that he might not spare him even though he is a suppliant. This is the same violent temper that made him refuse Hector's dying plea in Book 22. He also makes it clear that he is returning Hector because Zeus has sent Thetis with a message, not simply out of pity.
However, the source also shows a change: Achilles is now controlling his anger, and he respects both the gods' commands and Priam's courage in coming to the camp. In Book 22 he wished he could 'eat raw' Hector's flesh and dragged his body behind his chariot; in Book 24 he weeps with Priam, raises him by the hand, 'pitying his grey head and grey beard', and praises his courage. His speech about the two jars of Zeus shows that he now sees his own suffering and Priam's as part of the same human condition.
His actions confirm the change. He has the body washed out of Priam's sight, because he knows that Priam's grief might make him lose his temper and kill him - which shows self-awareness. He lifts Hector onto the bier himself, asks Patroclus to forgive him, and tells the story of Niobe to persuade Priam to eat.
Overall, Achilles is presented as changed in his pity and self-control, but not transformed: his anger is still there, and he must work hard to master it. That makes the change more believable and more moving.
Explanation
The source is deliberately double-edged: it shows Achilles' anger flaring up again, but also his obedience to Zeus and his self-control. The best answers use it to argue that the change is real but incomplete, comparing specific moments in Book 22 (the refusal, the raw flesh, the dragging) with Book 24 (tears, pity, washing the body, the bier).
