One night when he was buried in a deep sleep, there came to him a certain winged messenger, named Phoebus, who touched his feet, which were very hot, and said: 'Thou noble knight, since thou hast wandered through many cities and kingdoms and suffered many things at sea, in battle, and in the lists, the heavenly Father has bidden me make known to thee the following means of obtaining thy prayer: Take blood from thy right side, and from the left side of thy spouse.

For this blood is the heart's blood of your parents, and though it may seem to be of two kinds, yet, in reality, it is only one.

Mix the two kinds of blood, and keep the mixture tightly enclosed in the globe of the seven wise Masters.

Then that which is generated will be nourished with its own flesh and blood, and will complete its course of development when the Moon has changed for the eighth time.

If thou repeat this process again and again, thou shalt see children's children, and the offspring of thy body shall fill the world.' When Phoebus had thus spoken, he winged his flight heavenward.
