His tears run down his beard, like winter’s drops
From eaves of reeds.

– William Shakespeare

The Tempest, Act 5, Scene 1. Ariel tells Prospero how "The good old lord Gonzalo" is full or sorrow and dismay. In a simile he compares the tears running down his bears to cold raindrops falling from a thatched roof. At this point Alonso and his followers are imprisoned in the grove and in a state of distraction after Ariel worked his magic charms on them.
