Quis Rerum Divinarum Heres Sit

But the idea of equality is a necessary one, and so is that of equality in proportion, according to which a few things are looked upon as equal to many, and small things are equal to larger ones. And their proportionate equality, cities are accustomed to use at suitable times, when they command every citizen to contribute an equal share of his property, not equal in number, but in proportion to the value of his assessment, so that in some cases he who

These things being thus previously sketched out, see now how God, dividing things in the middle, has divided them into equal portions according to all the ideas of equality which occur in the creation of the universe. He has divided the heavy things so as to make them equal in number to the light ones, two to two; that is to say, so that the earth and the water, being things of weight, are equal in number to those which are by nature light, air, and fire. Again, he has made one equal to one, the driest thing to the wettest thing, the earth to the water; and the coldest thing to the hottest thing, the air to the fire. So, in the same manner, he has divided light from darkness, and day from night, and summer from winter, and autumn from spring; and so on.

Again, he has divided things so as to make his divisions equal in point of magnitude; such as the parallel cycles in heaven, and those which belong to the equinoxes both of spring and autumn, and those which belong to the winter and summer solstice. And on the earth he has divided the zones, two being equal to one another, which being placed close to the poles are frozen with cold, and on this account are uninhabitable. And two he has placed on the borders between these two and the torrid zone, and these two they say are the abode of a happy temperature of the air, one of them lying towards the south and the other towards the north.

Now the divisions of time are equal in point of length, the longest day being equal to the longest night, and again the shortest day being equal to the shortest night, and the mean length of day to the mean length of night. And the equal magnitude of other days and nights appears to be indicated chiefly by the equinoxes.
