causes it to emit burning yet sweet emanations.[XXIV-19] Here is a more modest recipe for a cake; but then it does not claim the paternity of an emperor. However, Cato brought it much into fashion, for the wise Cato often busied himself in the science of cookery, for which reason he is greatly worthy of esteem. Well, we recommend to the reader the _Libum_ of that philosopher, who indicates the manner of preparing it:-- “Crush,” he says, “two pounds of cheese; mix with it a pound of rye flour, or, in order to render it lighter, throw in merely half a pound of wheat flour and an egg. Stir, mix, and work this paste; form of it a cake which you will place on leaves, and cook in a tart dish on the hot hearth.” This libum was much esteemed about twenty centuries ago; in honour of Cato may it again be brought to light, if not completely unworthy of our attention.[XXIV-20] Could we not also rehabilitate the reputation of the most celebrated of ancient pies, the _Placenta_, which so delighted mankind, and by which the gods even allowed their fury to be appeased?[XXIV-21] Renowned writers have granted it the authority of their praise;[XXIV-22] and the illustrious geoponist, already cited, describes with lengthened complaisance the manner of preparing this important dish:-- “Place, on one side, two pounds of rye flour, which will serve to form the foundation, on which must be placed biscuits, formed of crisp paste; on the other, put four pounds of wheat; and two pounds of alica (grains of fine wheat, stripped of their husks and crushed; to which was added, in order to whiten them, a peculiar kind of chalk found between Naples and Pouzzoli[XXIV-23]). This latter must be left to infuse in water, and, when well soaked, it must be thrown into a kneading trough, and well worked with the hand. You then mix with it the four pounds of wheat flour, in order to make the whole into biscuits, or dry marchpans. This paste must be worked in a basket, and, as it dries, each separate marchpan must be shaped. When they have acquired a convenient form, rub them on all sides with a piece of stuff soaked in oil, and the same must be done to the foundation of the placenta before placing the marchpans on it. During these preparations, make the hearth very hot, as well as the cover of the tart dish intended to cook it. Then spread the two pounds of rye flour you have in reserve over fourteen pounds of cheese of sheep’s milk. Make of this a light paste for the foundation already mentioned. This cheese ought to be very fresh, and previously soaked in three waters. It is allowed to drain slowly between the hands, and when it has been left to dry, it is kneaded. Take a flour sieve, and pass the cheese through it before mixing it with the rye. Then add four pounds and a half of good honey; mix well; place the foundation, furnished with its band, on a board a foot square, covered with bay leaves rubbed with oil, and form the placenta. Begin by covering the whole of the base with
