(1) Iximiprus saith:—I testify that the beginning of all things is a Certain Nature, which is perpetual, coequalling all things, and that the visible natures, with their births and decay, are times wherein the ends to which that nature brings them are beheld and summoned.* Now, I instruct you that the stars are igneous, and are kept within bounds by the air. If the humidity and density of the air did not exist to separate the flames of the sun from living things, then the Sun would consume all creatures. But God has provided the separating air, lest that which He has created should be burnt up. Do you not observe that the Sun when it rises in the heaven overcomes the air by its heat, and that the warmth penetrates from the upper to the lower parts of the air? If, then, the air did not presently breathe forth those winds whereby creatures are generated, the i Sun by its heat would certainly destroy all that lives. But the Sun is kept in check by the air, which thus conquers because it unites the heat of the Sun to its own heat, and the humidity of water to its own humidity. Have you not remarked how tenuous water.

is drawn up into the air by the action of the heat of the Sun, which thus helps the water against itself? If the water did not nourish the air by such tenuous moisture, assuredly the Sun would overcome the air. The fire, therefore, extracts moisture from the water, by means of which the air conquers the fire itself. Thus, fire and water are enemies between which there is no consanguinity, for the fire is hot and dry, but the water is cold and moist.. The air, which is warm and moist, joins these together by its concording medium; between the humidity of water and the heat of fire the air is thus placed to establish peace. And lock ye all how there shall arise a spirit from the tenuous vapour of the air, because the heat being joined to the humour, there necessarily issues something tenuous, which will become a wind. For the heat of the Sun extracts something tenuous out of the air, which also becomes spirit and life to all creatures. All this, however, is disposed in such manner by the will of God, and a coruscation appears when the heat of the Sun touches and breaks up a cloud.

The Turba saith:—Well hast thou described the fire, even as thou knowest concerning it, and thou hast believed the word of thy brother.

(5) And if from smoke a fire may be inferred, Such an oblivion clearly demonstrates Some error in thy will elsewhere intent. Truly from this time forward shall my words Be naked, so far as it is befitting To lay them open unto thy rude gaze." And more coruscant and with slower steps The sun was holding the meridian circle, Which, with the point of view, shifts here and there When halted (as he cometh to a halt, Who goes before a squadron as its escort, If something new he find upon his way) The ladies seven at a dark shadow's edge, Such as, beneath green leaves and branches black, The Alp upon its frigid border wears. In front of them the Tigris and Euphrates Methought I saw forth issue from one fountain, And slowly part, like friends, from one another. "O light, O glory of the human race! What stream is this which here unfolds itself From out one source, and from itself withdraws?"

(5) 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.
