for now the different fruits are produced in turn, at different seasons, and not all together at one time; for who is there who does not know that first of all comes the sowing and the planting; and, in the second place, the growth of what has been sown and planted, in some cases the plants extending their roots downwards like foundations, and in others raising themselves upwards to a height and displaying long stalks? After that come the buds, and the putting forth of leaves, and then after everything else comes the production of fruit. And again, the fruit when first produced is not perfect, but it contains in itself all kinds of change, with reference both to its quantity in regard of magnitude, and to its qualities in its multiform appearance: for the fruit is produced at first like indivisible grains, which are hardly visible from their diminutive size, and which one might correctly enough pronounce to be the first things perceptible by the external senses; and afterwards by little and little, from the nourishment conveyed in channels, which waters the tree, and from the wholesome effect of the breezes, which blow air at the same time cold and gentle, the fruit is gradually vivified, and nursed up, and increased, advancing onward to its perfect size; and with its change of magnitude it changes also its qualities, as if it were diversified with varying colours by pictorial science.

Accordingly he commanded the earth to produce these things. And the earth, as though it had for a long time been pregnant and travailing, produced every sort of seed, and every sort of tree, and also of fruit, in unspeakable abundance; and not only were these produced fruits to be food for living animals, but enough also to serve as a preparation for the continuous production of similar fruits hereafter; covering substances consisting of seed, in which are the principles of all plants undistinguishable and invisible, but destined hereafter to become manifest and visible in the periodical maturity of the fruit.

For God thought fit to endue nature with a long duration, making the races that he was creating immortal, and giving them a participation in eternity. On which account he led on and hastened the beginning towards the end, and caused the end to turn backwards to the beginning: for from plants comes fruit, as the end might come from the beginning; and from the fruit comes the seed, which again contains the plant within itself, so that a fresh beginning may come from the end.
