For Parmenides [92] likewise supposes the universe to be one, both eternal and unbegotten, and of a spherical form. And neither did he escape the opinion of the great body (of speculators), affirming fire and earth to be the originating principles of the universe -- the earth as matter, but the fire as cause, even an efficient one. He asserted that the world would be destroyed, but in what way he does not mention. [93] The same (philosopher), however, affirmed the universe to be eternal, and not generated, and of spherical form and homogeneous, but not having a figure in itself, and immoveable and limited.
