text: Posidonius then passes on to the farmer. With no less eloquence he describes the ground which is broken up and crossed again by the plough, so that the earth, thus loosened, may allow freer play to the roots; then the seed is sown, and the weeds plucked out by hand, lest any chance growth or wild plant spring up and spoil the crop. This trade also, he declares, is the creation of the wise, – just as if cultivators of the soil were not even at the present day discovering countless new methods of increasing the soil's fertility! Furthermore, not confining his attention to these arts, he even degrades the wise man by sending him to the mill. For he tells us how the sage, by imitating the processes of nature, began to make bread. "The grain," he says, "once taken into the mouth, is crushed by the flinty teeth, which meet in hostile encounter, and whatever grain slips out the tongue turns back to the selfsame teeth. Then it is blended into a mass, that it may the more easily pass down the slippery throat. When this has reached the stomach, it is digested by the stomach's equable heat; then, and not till then, it is assimilated with the body. Following this pattern," he goes on, "someone placed two rough stones, the one above the other, in imitation of the teeth, one set of which is stationary and awaits the motion of the other set. Then, by the rubbing of the one stone against the other, the grain is crushed and brought back again and again, until by frequent rubbing it is reduced to powder. Then this man sprinkled the meal with water, and by continued manipulation subdued the mass and moulded the loaf. This loaf was, at first, baked by hot ashes or by an earthen vessel glowing hot; later on ovens were gradually discovered and the other devices whose heat will render obedience to the sage's will." Posidonius came very near declaring that even the cobbler's trade was the discovery of the wise man.
