Lord Byron Quote

Who hath not proved how feebly words essay
To fix one spark of beauty's heavenly ray?
Who doth not feel, until his failing sight
Faints into dimness with its own delight,
His changing cheek, his sinking heart, confess
The might, the majesty of loveliness?

Canto I, stanza 6 - The Bride of Abydos (1813)
