Hippolytus

“ The inscription of the book is, he says, sufficient for a knowledge of the universe. For this is (equivalent in meaning with) generation, (that is,) vision, into which one section of the river is divided. For the world was seen by the power of vision. Again, the inscription of the second book is Exodus. For what has been produced, passing through the Red Sea, must come into the wilderness,—now they say he calls the Red (Sea) blood,—and taste bitter water. ”
