Several Worlds in Several Circles

There may be many worlds like circles round;
In after ages more worlds may be found.1
If we by art of shipping could into2
Each circle slip, we might perhaps it know.3
This world compared to some may be but small:              5
No doubt but4 Nature made degrees of all.
If not, Drake ne’er had made so quick a skip5
About the largest circle in6 his7 ship.
For8 some may be so big as none can swim,
Had they the life of old Methusalem.                                  10
Or had they lives to number with each day,
They would want time to compass half the way.
But if that Drake had lived in Venus’s9 star,
His journey shorter might have10 been by far.
