How, in due course, we are to go to sleep, in remembrance of the precepts of temperance, we must now say. For after the repast, having given thanks to God for our participation in our enjoyments, and for the [happy] passing of the day, our talk must be turned to sleep. Magnificence of bed-clothes, gold-embroidered carpets, and smooth carpets worked with gold, and long fine robes of purple, and costly fleecy cloaks, and manufactured rugs of purple, and mantles of thick pile, and couches softer than sleep, are to be banished. For, besides the reproach of voluptuousness, sleeping on downy feathers is injurious, when our bodies fall down as into a yawning hollow, on account of the softness of the bedding. For they are not convenient for sleepers turning in them, on account of the bed rising into a hill on either side of the body. Nor are they suitable for the digestion of the food, but rather for burning it up, and so destroying the nutriment. But stretching one’s self on even couches, affording a kind of natural gymnasium for sleep, contributes to the digestion of the food. And those that can roll on other beds, having this, as it were, for a natural gymnasium for sleep, digest food more easily, and render themselves fitter for emergencies. Moreover, silver-footed couches argue great ostentation; and the ivory on beds, the body having left the soul, is not permissible for holy men, being a lazy contrivance for rest. We must not occupy our thoughts about these things, for the use of them is not forbidden to those who possess them; but solicitude about them is prohibited, for happiness is not to be found in them. On the other hand, it savours of cynic vanity for a man to act as Diomede,-- “And he stretched himself under a wild bull’s hide,”[557]-- unless circumstances compel. Ulysses rectified the unevenness of the nuptial couch with a stone. Such frugality and self-help was practised not by private individuals alone, but by the chiefs of the ancient Greeks. But why speak of these? Jacob slept on the ground, and a stone served him for a pillow; and then was he counted worthy to behold the vision--that was above man. And in conformity with reason, the bed which we use must be simple and frugal, and so constructed that, by avoiding the extremes [of too much indulgence and too much endurance], it may be comfortable: if it is warm, to protect us; if cold, to warm us. But let not the couch be elaborate, and let it have smooth feet; for elaborate turnings form occasionally paths for creeping things which twine themselves about the incisions of the work, and do not slip off.
