Piping down the valleys wild, Piping songs of pleasant glee, On a cloud I saw a child, And he laughing said to me: "Pipe a song about a Lamb." So I piped with merry cheer; "Piper, pipe that song again." So I piped; he wept to hear.
William BlakeDown the winding cavern we groped our tedious way, till a void boundless as the nether sky appeared beneath us, and we held by the roots of trees and hung over this immensity; but I said: if you please we will commit ourselves to this void and see whether providence is here also.
William Blake
