(25) He has placed in the firmament the orb of the proud, and binds it with iron when glowing red it wanes.

(54) And there mine eyes saw how they made these their instruments, iron chains of immeasurable weight.

(12) But its height or distance cannot be exactly known. But I am fully persuaded that it is in the midst, in the deep between Jupiter and the general sphere of the fixed stars or constellations, for it is the heart of the corporeity in nature.

(4) Some naturalists [scientists] or artists have undertaken to measure that height and distance, and have produced many strange and monstrous devices. Indeed, before this my knowledge and revelation of God, I held that only to be the true heaven, which in a round circumference and sphere, very azure of a light blue colour, extends itself above the stars, supposing that God had therein his peculiar being, and did rule only in the power of his holy spirit in this world.

(9) And ween not, for I call it a darkness or a cloud, that it be any cloud congealed of the humours that flee in the air, nor yet any darkness such as is in thine house on nights when the candle is out. For such a darkness and such a cloud mayest thou imagine with curiosity of wit, for to bear before thine eyes in the lightest day of summer: and also contrariwise in the darkest night of winter, thou mayest imagine a clear shining light. Let be such falsehood. I mean not thus. For when I say darkness, I mean a lacking of knowing: as all that thing that thou knowest not, or else that thou hast forgotten, it is dark to thee; for thou seest it not with thy ghostly eye. And for this reason it is not called a cloud of the air, but a cloud of unknowing, that is betwixt thee and thy God.

(3) Anaxacoras saith:—I make known that the beginning of all those things which God hath created is weight and proportion,* for weight rules all things, and the weight and spissitude of the earth is manifest in proportion; but weight is not found except in body. And know, all ye Turba, that the spissitude of the four elements reposes in the earth; for the spissitude of fire falls into air, the spissitude of air, together with the spissitude received from the fire, falls into water; the spissitude also of water, increased by the spissitude of fire and air, reposes in earth. Have you not observed how the spissitude of the four elements is conjoined in earth? The same, therefore, is more inspissated than all.

Then saith the Turba: —Thou hast well spoken. Verily the earth is more inspissated than are the rest. Which, therefore, is the most rare of the four elements and is most worthy to possess the rarity of these four?

He answereth:—Fire is the most rare among all, and thereunto cometh what is rare of these four. But air is less rare than fire, because it is warm and moist, while fire is warm and dry; now that which is warm and dry is more rare than the warm and moist. They say unto him: —Which element is of less rarity than air?

He answereth:—Water, since cold and moisture inhere therein, and every cold humid is of less rarity than a warm humid.

Then do they say unto him:—Thou hast spoken truly. What, therefore, is of less rarity than water?

He answereth:-—Earth, because it is cold and dry, and that which is cold and dry is of less rarity than that which is cold and moist.

PyTHAGoRAS saith:—Well have ye provided, O Sons of the Doctrine, the description of these four natures,* out of which God hath created all things. Blessed, therefore, is he who comprehends what ye have declared, for from the apex of the world he shall not find an intention greater than his own! Let us, therefore, make perfect our discourse.

They reply:—Direct every one to take up our speech in turn. Speak thou, O Pandolfus!
