Like the snow or freezing hail that pelts from clouds
when the North Wind born in the clear heaven blasts it on –
so in an eager rush of speed the Wind-swift Iris flew.
– Homer
The Iliad, Book 15, lines 203-205. Homer uses an epic simile about snow or hail driven by the North Wind to describe the speed with which messenger god Iris flew to deliver Zeus’s order to Poseidon to quit the war.
