   • 1896, Matthew Phipps Shiel, Vaila:

     My flesh writhed like the glutinous flesh of a serpent. Slowly moved, and stopped: -- then was a sweep -- and a swirl -- and a pause! then a swirl -- and a sweep -- and a pause! -- then steady industry of labour on the monstrous brazen axis, as the husbandman plods by the plough; then increase of zest, assuetude of a fledgeling to the wing -- then intensity -- then the last light ecstasy of flight.
