either side of the navel two air-ducts are stretched to convey the
breath, and two veins[24] to convey blood. But when, he says, the
navel going forth from the region of Eden is attached to the foetus
in the epigastric regions, that which is commonly called by
everyone the navel[25] ... and the two veins by which the blood
flows and is carried from the Edenic region through what are called
the gates of the liver, which nourish the foetus. And the
air-ducts, which we said were channels for breath, embracing the
bladder on either side in the region of the pelvis, are united at
the great duct which is called the dorsal aorta. And thus the
breath passing through the side doors towards the heart produces
the movement of the embryo. For as long as the babe is being
fashioned in the Garden, it neither takes nourishment through the
mouth, nor breathes through the nostrils. For seeing that it is
surrounded by the waters (of the womb), death would instantly
supervene, if it took a breath; for it would draw after it the
waters and so perish. But the whole (of the foetus) is wrapped up
in an envelope, called the amnion, and is nourished through the
navel and receives the essence of the breath through the dorsal
duct, as I have said.

15. The river, therefore, he says, which goes out of Eden, is
divided into four channels, four ducts, that is to say; into four
senses of the foetus: sight, (hearing),[26] smelling, taste and
touch. For these are the only senses the child has while it is
being formed in the Garden.

This, he says, is the law which Moses laid down, and in accordance
with this very law each of his books was written, as the titles
show. The first book is _Genesis_, and the title of the book, he
