The poem
Give me a golden pen, and let me lean On heaped-up flowers, in regions clear, and far; Bring me a tablet whiter than a star, Or hand of hymning angel, when 'tis seen The silver strings of heavenly harp atween: And let there glide by many a pearly car Pink robes, and wavy hair, and diamond jar, And half-discovered wings, and glances keen. The while let music wander round my ears, And as it reaches each delicious ending, Let me write down a line of glorious tone, And full of many wonders of the spheres: For what a height my spirit is contending! 'Tis not content so soon to be alone.
This poem by Keats is about a friend that died well before their time. Death in youth is truly very sad event but it can also be something glorious, golden, and heaped with flowers and music for the heart and soul.
