I've watched you now a full half-hour; Self-poised upon that yellow flower And, little Butterfly! Indeed I know not if you sleep or feed. How motionless! - not frozen seas More motionless! and then What joy awaits you, when the breeze Hath found you out among the trees, And calls you forth again!

William Wordsworth, Stephen Gill (2000). “The Major Works”, p.254, Oxford University Press, USA
