John Keats,
The Complete Poetical Works and Letters of John Keats…
“ It has been said, dear George, and true I hold it, (For knightly Spenser to Libertas told it,) That when a Poet is in such a trance, In air he sees white coursers paw and prance, Bestridden of gay knights, in gay apparel, Who at each other tilt in playful quarrel; And what we, ignorantly, sheet-lightning call, Is the swift opening of their wide portal,30 When the bright warder blows his trumpet clear, Whose tones reach nought on earth but Poet's ear. ”
