5 Having thus formed the world, he (the Demiurge) also created the earthy [part of] man, not taking him from this dry earth, but from an invisible substance consisting of fusible and fluid matter, and then afterwards, as they define the process, breathed into him the animal part of his nature. It was this latter which was created after his image and likeness. The material part, indeed, was very near to God, so far as the image went, but not of the same substance with him. The animal, on the other hand, was so in respect to likeness; and hence his substance was called the spirit of life, because it took its rise from a spiritual outflowing. After all this, he was, they say, enveloped all round with a covering of skin; and by this they mean the outward sensitive flesh.
