Poems (1817) is John Keats’ first publication of poems. It includes, among light-occluding others, his Sleep and Poetry — from which this suckled quote was sucked:

Stop and consider! life is but a day;
A fragile dew-drop on its perilous way
From a tree’s summit; a poor Indian’s sleep
While his boat hastens to the monstrous steep
Of Montmorenci.
