I saw young Harry, with his beaver on, His cuisses on his thighs, gallantly armd, Rise from the ground like featherd Mercury, And vaulted with such ease into his seat As if an angel droppd down from the clouds, To turn and wind a fiery Pegasus, And witch the world with noble horsemanship. Shakespeare.King Henry IV., Part I. Act IV. Scene 1. (Sir Richard Vernon to Hotspur.)
