Note 3 — Early Poems (continued 2)
Reading edition
“The shadow of Saturn thrown upon the bright ring that surrounds the planet appears motionless, though the body of the planet revolves. Saturn rotates on its axis in the short period of ten and a half hours, but the shadow of this swiftly whirling mass shows no more motion than is seen in the shadow of a top spinning so rapidly that it seems to be standing still.” Rowe and Webb’s note, which I gladly borrow.
