the lot fell to Teucer to shoot first…
He quickly loosed an arrow, full-draw force
but never swore to the Archer
he’d slaughter splendid victims, newborn lambs,
so he missed the dove – Apollo grudged him that.

– Homer

The Iliad, Book 23, lines 955-959. If you don’t keep the gods sweet you quickly find yourself in trouble. Teucer comes second in the archery competition, because he didn’t pray and sacrifice to Apollo. So the archer god paid him back.
