Case Description: Complainant (Zeus) accuses Defendant (Iris) of arson and stirring up a war. Not long after Aeneas finally made it to Italy, Iris not only inspired a bunch of people to burn up Aeneas's ships, she also inspired Turnus to start a war with Aeneas.
Case Status: Case dismissed. Iris was just following the orders of her mistress, Hera, and can't be held accountable. The rainbow goddess also helped guide the soul of poor Dido away from the flames, so Aeneas ought to be grateful to her.
