Of Many Worlds in This World by John Dryden (1631-1700)
Just like as in a nest of boxes round,
Degrees of sizes of each box are found:
So, in this world, many many others be
Thinner and less, and less still by degree:
Although they are not subject to our sense,
A world may be no bigger than two-pence.
Nature is curious, and such works may shape,
Which our dull senses easily escape:
For creatures, small as atoms, may be there,
If every one a creature's figure bear.
If atoms four, a world can make, then see
What several worlds might in an ear-ring be:
For, millions of these atoms may be in
The head of one small, little, single pin.
And if thus small, then ladies may well wear
A world of worlds, as pendents in each ear.
