Then Sisyphus in torment I beheld
Being roustabout to a tremendous boulder.
Leaning with both arms braced and legs driving,
He heaved it toward a height, and almost over,
But then a Power spun him round and sent
The cruel boulder bounding again to the plain.
Whereupon the man bent down again to toil
Dripping sweat, and the dust rose.
