Down he strode from Olympus’ peaks, storming at heart
with his bow and hooded quiver slung across his shoulders…
First he went for the mules and circling dogs but then,
launching a piercing shaft at the men themselves,
he cut them down in droves.

– Homer

The Iliad, Book 1, lines 51-59. Apollo, a god of healing, sends a plague to the Greek camp which kills many soldiers. He has been angered by Agamemnon’s offense to Apollo’s priest Chryses in refusing a ransom to free the priest’s daughter Chryseis.
