Philo Judaeus De Opificio Mundi 41

[41] 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.
