5. For first of all he framed in it formless matter, as a substance capable of receiving all forms. He next, by the power of the number two, imparted quality to matter, and gave beauty to that which before was void of all grace. Again, by means of the number three, he framed a body compounded of matter and form, and presenting the three dimensions of breadth, and length, and depth. Then, from the doubling of the number two, he devised the quaternion of the elements, earth, water, air, and fire, and ordained them to be everlasting sources for the supply of this universe. Again, the number four produces the number ten. For the aggregate of one, and two, and three, and four, is ten. And three multiplied with ten discovers the period of a month: and twelve successive months complete the course of the sun. Hence the revolutions of years, and changes of the seasons, which give grace, like variety of color in painting, to that eternity which before was formless and devoid of beauty, for the refreshment and delight of those whose lot it is to traverse therein the course of life.
