Book XIII, lines 24–29
Compare:
As on the smooth expanse of crystal lakes
The sinking stone at first a circle makes;
The trembling surface, by the motion stirred,
Spreads in a second circle, then a third;
Wide, and more wide, the floating rings advance,
Fill all the watery plain, and to the margin dance.
Alexander Pope, Temple of Fame, lines 436–441
As the small pebble stirs the peaceful lake:
The centre moved, a circle straight succeeds,
Another still, and still another spreads.
Alexander Pope, Essay on Man, Ep. IV, lines 364–367
