6. Survey creation; you will see the power of heat reigning over all that is born and perishes. On account of it comes all the water spread over the earth, as well as that which is beyond our sight and is dispersed in the depths of the earth. On account of it are abundance of fountains, springs or wells, courses of rivers, both mountain torrents and ever flowing streams, for the storing of moisture in many and various reservoirs. From the East, from the winter solstice flows the Indus, the greatest river of the earth, according to geographers. From the middle of the East proceed the Bactrus, [1484] the Choaspes, [1485] and the Araxes, [1486] from which the Tanais [1487] detaches itself to fall into the Palus-Mæotis. [1488] Add to these the Phasis [1489] which descends from Mount Caucasus, and countless other rivers, which, from northern regions, flow into the Euxine Sea. From the warm countries of the West, from the foot of the Pyrenees, arise the Tartessus [1490] and the Ister, [1491] of which the one discharges itself into the sea beyond the Pillars and the other, after flowing through Europe, falls into Euxine Sea. Is there any need to enumerate those which the Ripæan mountains [1492] pour forth in the heart of Scythia, the Rhone, [1493] and so many other rivers, all navigable, which after having watered the countries of the western Gauls and of Celts and of the neighbouring barbarians, flow into the Western sea? And others from the higher regions of the South flow through Ethiopia, to discharge themselves some into our sea, others into inaccessible seas, the Ægon [1494] the Nyses, the Chremetes, [1495] and above all the Nile, which is not of the character of a river when, like a sea, it inundates Egypt. Thus the habitable part of our earth is surrounded by water, linked together by vast seas and irrigated by countless perennial rivers, thanks to the ineffable wisdom of Him Who ordered all to prevent this rival element to fire from being entirely destroyed.
However, a time will come, when all shall be consumed by fire; as Isaiah says of the God of the universe in these words, "That saith to the deep, Be dry, and I will dry up thy rivers." [1496] Reject then the foolish wisdom of this world, [1497] and receive with me the more simple but infallible doctrine of truth.
7. Therefore we read: "Let there be a firmament in the midst of the waters, and let it divide the waters from the waters." I have said what the word firmament in Scripture means. It is not in reality a firm and solid substance which has weight and resistance; this name would otherwise have better suited the earth. But, as the substance of superincumbent bodies is light, without consistency, and cannot be grasped by any one of our senses, it is in comparison with these pure and imperceptible substances that the firmament has received its name. Imagine a place fit to divide the moisture, sending it, if pure and filtered, into higher regions, and making it fall, if it is dense and earthy; to the end that by the gradual withdrawal of the moist particles the same temperature may be preserved from the beginning to the end. You do not believe in this prodigious quantity of water; but you do not take into account the prodigious quantity of heat, less considerable no doubt in bulk, but exceedingly powerful nevertheless, if you consider it as destructive of moisture. It attracts surrounding moisture, as the melon shows us, and consumes it as quickly when attracted, as the flame of the lamp draws to it the fuel supplied by the wick and burns it up. Who doubts that the æther is an ardent fire? [1498] If an impassable limit had not been assigned to it by the Creator, what would prevent it from setting on fire and consuming all that is near it, and absorbing all the moisture from existing things? The aerial waters which veil the heavens with vapours that are sent forth by rivers, fountains, marshes, lakes, and seas, prevent the æther from invading and burning up the universe. Thus we see even this sun, in the summer season, dry up in a moment a damp and marshy country, and make it perfectly arid. What has become of all the water? Let these masters of omniscience tell us. Is it not plain to every one that it has risen in vapour, and has been consumed by the heat of the sun? They say, none the less, that even the sun is without heat. What time they lose in words! And see what proof they lean upon to resist what is perfectly plain. Its colour is white, and neither reddish nor yellow. It is not then fiery by nature, and its heat results, they say, from the velocity of its rotation. [1499] What do they gain? That the sun does not seem to absorb moisture? I do not, however, reject this statement, although it is false, because it helps my argument. I said that the consumption of heat required this prodigious quantity of water. That the sun owes its heat to its nature, or that heat results from its action, makes no difference, provided that it produces the same effects upon the same matter. If you kindle fire by rubbing two pieces of wood together, or if you light them by holding them to a flame, you will have absolutely the same effect. Besides, we see that the great wisdom of Him who governs all, makes the sun travel from one region to another, for fear that, if it remained always in the same place, its excessive heat would destroy the order of the universe. Now it passes into southern regions about the time of the winter solstice, now it returns to the sign of the equinox; from thence it betakes itself to northern regions during the summer solstice, and keeps up by this imperceptible passage a pleasant temperature throughout all the world.
Let the learned people see if they do not disagree among themselves. The water which the sun consumes is, they say, what prevents the sea from rising and flooding the rivers; the warmth of the sun leaves behind the salts and the bitterness of the waters, and absorbs from them the pure and drinkable particles, [1500] thanks to the singular virtue of this planet in attracting all that is light and in allowing to fall, like mud and sediment, all which is thick and earthy. From thence come the bitterness, the salt taste and the power of withering and drying up which are characteristic of the sea. While as is notorious, they hold these views, they shift their ground and say that moisture cannot be lessened by the sun. [1501]
8. "And God called the firmament heaven." [1502] The nature of right belongs to another, and the firmament only shares it on account of its resemblance to heaven. We often find the visible region called heaven, on account of the density and continuity of the air within our ken, and deriving its name "heaven" from the word which means to see. [1503] It is of it that Scripture says, "The fowl of the air," [1504] "Fowl that may fly...in the open firmament of heaven;" [1505] and, elsewhere, "They mount up to heaven." [1506] Moses, blessing the tribe of Joseph, desires for it the fruits and the dews of heaven, of the suns of summer and the conjunctions of the moon, and blessings from the tops of the mountains and from the everlasting hills, [1507] in one word, from all which fertilises the earth. In the curses on Israel it is said, "And thy heaven that is over thy head shall be brass." [1508] What does this mean? It threatens him with a complete drought, with an absence of the aerial waters which cause the fruits of the earth to be brought forth and to grow.
Since, then, Scripture says that the dew or the rain falls from heaven, we understand that it is from those waters which have been ordered to occupy the higher regions. When the exhalations from the earth, gathered together in the heights of the air, are condensed under the pressure of the wind, this aerial moisture diffuses itself in vaporous and light clouds; then mingling again, it forms drops which fall, dragged down by their own weight; and this is the origin of rain. When water beaten by the violence of the wind, changes into foam, and passing through excessive cold quite freezes, it breaks the cloud, and falls as snow. [1509] You can thus account for all the moist substances that the air suspends over our heads.
And do not let any one compare with the inquisitive discussions of philosophers upon the heavens, the simple and inartificial character of the utterances of the Spirit; as the beauty of chaste women surpasses that of a harlot, [1510] so our arguments are superior to those of our opponents. They only seek to persuade by forced reasoning. With us truth presents itself naked and without artifice. But why torment ourselves to refute the errors of philosophers, when it is sufficient to produce their mutually contradictory books, and, as quiet spectators, to watch the war? [1511] For those thinkers are not less numerous, nor less celebrated, nor more sober in speech in fighting their adversaries, who say that the universe is being consumed by fire, and that from the seeds which remain in the ashes of the burnt world all is being brought to life again. Hence in the world there is destruction and palingenesis to infinity. [1512] All, equally far from the truth, find each on their side by-ways which lead them to error.
9. But as far as concerns the separation of the waters I am obliged to contest the opinion of certain writers in the Church [1513] who, under the shadow of high and sublime conceptions, have launched out into metaphor, and have only seen in the waters a figure to denote spiritual and incorporeal powers. In the higher regions, above the firmament, dwell the better; in the lower regions, earth and matter are the dwelling place of the malignant. So, say they, God is praised by the waters that are above the heaven, that is to say, by the good powers, the purity of whose soul makes them worthy to sing the praises of God. And the waters which are under the heaven represent the wicked spirits, who from their natural height have fallen into the abyss of evil. Turbulent, seditious, agitated by the tumultuous waves of passion, they have received the name of sea, because of the instability and the inconstancy of their movements. [1514] Let us reject these theories as dreams and old women's tales. Let us understand that by water water is meant; for the dividing of the waters by the firmament let us accept the reason which has been given us. Although, however, waters above the heaven are invited to give glory to the Lord of the Universe, do not let us think of them as intelligent beings; the heavens are not alive because they "declare the glory of God," nor the firmament a sensible being because it "sheweth His handiwork." [1515] And if they tell you that the heavens mean contemplative powers, and the firmament active powers which produce good, we admire the theory as ingenious without being able to acknowledge the truth of it. For thus dew, the frost, cold and heat, which in Daniel are ordered to praise the Creator of all things, [1516] will be intelligent and invisible natures. But this is only a figure, accepted as such by enlightened minds, to complete the glory of the Creator. Besides, the waters above the heavens, these waters privileged by the virtue which they possess in themselves, are not the only waters to celebrate the praises of God. "Praise the Lord from the earth, ye dragons and all deeps." [1517] Thus the singer of the Psalms does not reject the deeps which our inventors of allegories rank in the divisions of evil; he admits them to the universal choir of creation, and the deeps sing in their language a harmonious hymn to the glory of the Creator.
10. "And God saw that it was good." God does not judge of the beauty of His work by the charm of the eyes, and He does not form the same idea of beauty that we do. What He esteems beautiful is that which presents in its perfection all the fitness [1518] of art, and that which tends to the usefulness of its end. He, then, who proposed to Himself a manifest design in His works, approved each one of them, as fulfilling its end in accordance with His creative purpose. A hand, an eye, or any portion of a statue lying apart from the rest, would look beautiful to no one. But if each be restored to its own place, the beauty of proportion, until now almost unperceived, would strike even the most uncultivated. But the artist, before uniting the parts of his work, distinguishes and recognises the beauty of each of them, thinking of the object that he has in view. It is thus that Scripture depicts to us the Supreme Artist, praising each one of His works; soon, when His work is complete, He will accord well deserved praise to the whole together. Let me here end my discourse on the second day, to allow my industrious hearers to examine what they have just heard. May their memory retain it for the profit of their soul; may they by careful meditation inwardly digest and benefit by what I say. As for those who live by their work, let me allow them to attend all day to their business, so that they may come, with a soul free from anxiety, to the banquet of my discourse in the evening. May God who, after having made such great things, put such weak words in my mouth, grant you the intelligence of His truth, so that you may raise yourselves from visible things to the invisible Being, and that the grandeur and beauty of creatures may give you a just idea of the Creator. For the visible things of Him from the creation of the world are clearly seen, and His power and divinity are eternal. [1519] Thus earth, air, sky, water, day, night, all visible things, remind us of who is our Benefactor. We shall not therefore give occasion to sin, we shall not give place to the enemy within us, if by unbroken recollection we keep God ever dwelling in our hearts, to Whom be all glory and all adoration, now and for ever, world without end. Amen.
