| Further, some have thought that the heaven encircles the universe and has the form of a sphere, and that everywhere it is the highest point, and that the center of the space enclosed by it is the lowest part: and, further, that those bodies that are light and airy are allotted by the Creator the upper region: while those that are heavy and tend to descend occupy the lower region, which is the middle. The element, then, that is lightest and most inclined to soar upwards is fire, and so they hold that its position is immediately after the heaven, and they call it ether, and after it comes the lower air. But earth and water, which are heavier and have more of a downward tendency, are suspended in the center. Therefore, taking them in the reverse order, we have in the lowest situation earth and water: but water is lighter than earth, and so is more easily set in motion: above these on all hands, like a covering; is the circle of air, and all round the air is the circle of ether, and outside air is the circle of the heaven. Further, they say that the heaven moves in a circle and so compresses all that is within it, that they remain firm and not liable to fall asunder. They say also that there are seven zones of the heaven, one higher than the other. And its nature, they say, is of extreme fineness, like that of smoke, and each zone contains one of the planets. For there are said to be seven planets: Sol, Luna, Jupiter, Mercury, Mars, Venus and Saturn. But sometimes Venus is called Lucifer and sometimes Vesper. These are called planets because their movements are the reverse of those of the heaven. For while the heaven and all other stars move from east to west, these alone move from west to east. And this can easily be seen in the case of the moon, which moves each evening a little backwards. All, therefore, who hold that the heaven is in the form of a sphere, say that it is equally removed and distant from the earth at all points, whether above, or sideways, or below. And by 'below' and ' sideways' I mean all that comes within the range of our senses. For it follows from what has been said, that the heaven occupies the whole of the upper region and the earth the whole of the lower. They say, besides, that the heaven encircles the earth in the manner of a sphere, and bears along with it in its most rapid revolutions sun, moon and stars, and that when the sun is over the earth it becomes day there, and when it is under the earth it is night. And, again, when the sun goes under the earth it is night here, but day yonder. Others have pictured the heaven as a hemisphere. This idea is suggested by these words of David, the singer of God, who stretchest out the heavens like a curtain, by which word he clearly means a tent: and by these from the blessed Isaiah, who has established the heavens like a vault: and also because when the sun, moon, and stars set they make a circuit round the earth from west to north, and so reach once more the east. Still, whether it is this way or that, all things have been made and established by the divine command, and have the divine will and counsel for a foundation that cannot be moved. For he himself spoke and they were made: he himself commanded and they were created. He has also established them for ever and ever: he has made a decree which will not pass. The heaven of heaven, then, is the first heaven which is above the firmament. So here we have two heavens, for God called the firmament also Heaven. And it is customary in the divine Scripture to speak of the air also as heavens, because we see it above us. Bless him, it says, all you birds of the heaven, meaning of the air. For it is the air and not the heaven that is the region in which birds fly. So here we have three heavens, as the divine Apostle said. But if you should wish to look upon the seven zones as seven heavens there is no injury done to the word of truth. For it is usual in the Hebrew tongue to speak of heaven in the plural, that is, as heavens, and when a Hebrew wishes to say heaven of heaven, he usually says heavens of heavens, and this clearly means heaven of heaven, which is above the firmament, and the waters which are above the heavens, whether it is the air and the firmament, or the seven zones of the firmament, or the firmament itself which are spoken of in the plural as heavens according to the Hebrew custom. | |
