Answer:
Apollo
Explanation:
We learn about the conflict that exists between Agamemnon and Apollo in Book 1 of The Illiad. In this book, we see that Agamemnon has claimed a woman called Chryseis, as it was tradition for soldiers to claim young women as their spoils of war. However, this woman was the daughter of Chryses, a priest of Apollo. Chryses decides to ask Apollo for retribution, and the god answers by sending a plague upon the Achaeans, who were commanded by Agamemnon.
