He lays down the two seasonal ones prior to the naturally-perforated one and to the Visvagyotis; for the last naturally-perforated one is the sky, and the last Visvagyotis (all-light brick) is the sun: he thus places the seasons on this side of the sky and the sun; whence the seasons are on this side thereof. But generative power there also is (in these seasonal bricks): he thus places generative power on this side of the sky and the sun; whence procreation takes place only on this side of them, but stationary, indeed, is procreation beyond them, for just as many gods as there were of old, so many there are now.
