Down 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 BlakeJerusalem (1804) And did those feet in ancient time Walk upon England's mountains green And was the holy lamb of God On England's pleasant pastures seen And did the countenance divine Shine forth upon our clouded hills And was Jerusalem builded here Among those dark Satanic mills Bring me my bow of burning gold Bring me my arrows of desire Bring me my spears o'clouds unfold Bring me my chariot of fire I will not cease from mental fight Nor shall my sword sleep in my hand 'Til we have built Jerusalem In England's green and pleasant land
William Blake
