seest so far off, is the Angel that hath the custody thereof, with a fiery sword: and although that thou thinkest thyself to be hard by, thou hast yet farther thither from hence, than thou hast ever been: the water that thou seest divided in four parts, is the water that issueth out of the Well in the middle of Paradise. The first is called Ganges or Phison, the second, Gihon or Nilus, the third Tigris, and the fourth Euphrates, also thou seest that he standeth under Libra and Aries right up towards the Zenith, and upon this fiery wall standeth the Angel Michael with his flaming sword to keep the tree of life the which he hath in charge; but the Spirit said unto Faustus, neither thou, nor I, nor any after us, yea all men whosoever are denied to visit it, or to come any nearer than we be. CHAPTER XXIV _Of a certain Comet that appeared in Germanie, and how Doctor Faustus was desired by certain friends of his to know the meaning thereof_ In Germanie over the Town of S. Eizleben was seen a mighty great Comet, whereat the people wondered; but Doctor Faustus being there, was asked of certain of his friends his judgment or opinion in the matter. Whereupon he answered, it falleth out often by the course and change of the Sun and Moon, that the Sun is under the earth, and the Moon above; but when the Moon draweth near the change, then is the Sun so strong that he taketh away all the light of the Moon, in such sort that he is as red as blood: and to the contrary, after they have been together, the Moon taketh her light again from him, and so increasing in light to the full, she will be as red as the Sun was before, and changeth herself into divers and sundry colours, of the which springeth a prodigious monster, or as you call it, a Comet, which is a figure or token appointed of God as a forewarning of his displeasure: as at one time he sendeth hunger, plague, sword, or such-like: being all tokens of his judgment: the which Comet cometh through the conjunction of the Sun and Moon begetting a monster, whose father is the Sun, and whose mother is the Moon, ☉ and ☽.
