   • 1847, Alfred Tennyson, The Princess:

     Yea, let her see me fall! and with that I drave
     Among the thickest and bore down a Prince,
     And Cyril, one. Yea, let me make my dream
     All that I would. But that large-moulded man,
     His visage all agrin as at a wake,
     Made at me through the press, and, staggering back
     With stroke on stroke the horse and horseman, came
     As comes a pillar of electric cloud,
     Flaying the roofs and sucking up the drains,
     And shadowing down the champaign till it strikes
