Final answer:
In "Musee des Beaux Arts," Auden uses the story of Icarus as an example of his theme of indifference.
Step-by-step explanation:
In Auden's poem "Musee des Beaux Arts," the mythological event that Auden uses as an example of his theme is the story of Icarus. This can be seen in the lines: "In Brueghel's Icarus, for instance: how everything turns away / Quite leisurely from the disaster; the ploughman may / Have heard the splash, the forsaken cry, / But for him it was not an important failure." Auden uses the story of Icarus to explore the theme of indifference and the idea that life goes on, even in the face of tragedy.
