the rocks pelted the ground like snow
that a sudden squall in fury, driving the dark clouds,
heaps thick-and-fast on the earth that feeds us all.
So the missiles showering from their hands.

– Homer

The Iliad, Book 12, lines 182-185. The Achaeans on their wall hurl rocks at the advancing Trojans in a bid to prevent them breaching their defenses. An epic simile likens it to snowflakes falling down thick and fast on the earth.
