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.

John Keats
