The rock is interposed (within) the teeth, as Homer says, "enclosure of teeth," that is, a wall anti fortress, in which exists the inner man, who thither has fallen from Adam, the primal man above. And he has been "severed without hands to effect the division," and has been borne down into the image of oblivion, being earthly and clayish. And he asserts that the twittering spirits follow him, that is, the Logos:- "Thus these, twittering, came together: and then the souls.
