ARISLEUS saith:—Know that the earth is a hill and not a plain, for which reason the Sun does not ascend over all the zones of the earth in a single hour; but if it were flat, the sun would rise in a moment over the whole earth. Parmenides saith:—Thou hast spoken briefly, O Arisleus! He answereth:— Is there anything the Master has left us which bears witness otherwise? Yet I testify that God is one, having never engendered or been begotten, and that the head of all things after Him is earth and fire, because fire is tenuous and light, and it rules all things on earth, but the earth, being ponderous and gross, sustains all things which are ruled by fire.
