A puddle of water no deeper than a single finger-breadth, which lies between
the stones on a paved street, offers us a view beneath the earth to a depth as
vast as the high gaping mouth of heaven stretches above the earth, so
that you seem to look down on the clouds and the heaven, and you discern
bodies hidden in the sky beneath the earth, marvellously.
