The Syrians imagined that man and woman, having been created in the fourth heaven, took it into their heads to eat a pancake instead of ambrosia which was their natural food. The ambrosia was exhaled through the pores, but after having eaten pancakes they had to go to stool. The man and the woman begged an angel to tell them where the closet was. 'Well,' replied the angel, 'You see that little planet, though it is so small, which is about 60 million leagues from here; it is the universe's privy; hurry there.' They went there, they were left there, and since then our world has been what it is.
