Among the cerealia, wheat, as Galen states, deservedly holds the first place, being in most general use and containing the most nutriment within a small bulk. He remarks, that it is the most glutinous of all the articles of this class.
Haly Abbas likewise states that wheat is the most nutritious of all articles of food. Pliny asserts the same thing of it. He calls the siligo the deliciæ tritici. Galen explains the siligo and similago in much the same terms as our author. The third species, or the autopyrus, he says, consists of all the parts of the grain, the bran not being excluded. Actuarius, on the other hand, says that the bran only is rejected. Is not the text of the latter corrupt? Bran, Galen adds, is detergent, and contains little nourishment. Modern commentators have been greatly puzzled to determine what the siligo, similago, and autopyrus of the ancients were. It appears impossible to reconcile all the different descriptions of them given by ancient writers, and therefore we cannot but suspect that some of them must have written from an imperfect acquaintance with the subject. Upon the whole, we are inclined to think that we shall not be far from the truth if we set them down as varieties of flour or bread, as regards quality, corresponding in a great measure, to the kinds of bread now distinguished by the names of the white, the wheaten, and the household. At all events the autopyrus is certainly analogous to the last. The furfuraceus, or panis cibarius of Celsus, was made solely from bran.
Theophrastus mentions that the lightest wheat imported to Greece in his time was the Pontic. It is curious to remark that Odessa wheat still retains its ancient character. The heaviest, he says, was the Sicilian, which, however, was lighter than the Bœotian. Pliny says that the lightest wheat brought to the Roman market was the Gallic, and then that imported from the Chersonese. The first in excellence, he adds, are the Bœotian, the Sicilian, and next to these the African.
Galen gives an interesting account of bread. The best kinds, he says, are such as contain plenty of leaven, have been properly pounded, and exposed to a moderate heat in the oven. When exposed to too strong a heat, he properly remarks that a crust is burned on the outside, while the inside is left raw or improperly concocted. Unleavened bread he wholly condemns. Celsus appears to have had a better opinion of it, for he ranks it first among those substances which do not spoil on the stomach. Of bread, in general, he correctly remarks, “Siquidem plus alimenti est in pane quam in ullo alio.” Pliny and Galen describe a soft spongy kind of bread, which would seem to have resembled that which we call buns. Pliny adds, that some nations prepare their bread with butter. He mentions a kind of bread called artolagani, which, according to Dr. Arbuthnot, answered to our cakes. Seth gives an interesting account of bread, but it is mostly extracted from Galen. Haly Abbas says, that the best kind of bread is that which is made from wheaten flour and salt, and is fermented, and heated in an oven to such a degree as not to burn the outer crust. Rhases disapproves entirely of unleavened bread. Serapion states that old bread is astringent. Avenzoar prefers newly-made bread, provided it has been cooled. Hippocrates condemns the eating of bread before it has been properly cooled. (De Diæt. i.) He mentions only two kinds of bread, the fine and the coarse—autopyrus. (De Vet. Med. 14.) According to Actuarius, the lightest kinds of wheat form the best bread for indolent persons, but persons actively employed require the weightiest kinds. Unleavened bread, he says, is very indigestible. Bread prepared with oil, he adds, is very nutritious, but requires a strong stomach to digest it. See an interesting account of the various kinds of bread in Athenæus (Deipnos. ii, 26.) He makes the remark that the worst kind is the most laxative. Among the kinds of bread described by ancient authors may be noticed the oxylipus mentioned by Galen (Meth. Med. viii, 5), which, as Manardus remarks, was prepared with vinegar. Another kind, called νάστος, was fermented with honey, dried grapes, &c. See Tzetzes (ad Lycoph. Casan. 640.) It is to be borne in mind that the ancients generally used leaven to ferment their bread. Pliny, however, mentions that the Gauls and Spaniards were in the practice of using yeast. (H. N. xviii, 7.)
The zea, typha, and olyra of the Greeks, and the far and adoreum of the Romans, were all varieties of spelt, a species of grain bearing some resemblance to wheat; in short, it was the triticum spelta L. Actuarius calls it a light, and not very nutritious grain. The chondrus was prepared from spelt, by first separating the husks, and then breaking it down into granules. The alica was the same as the chondrus, with only the addition of a small quantity of chalk; and, indeed, almost all the writers on Dietetics, except our author, use them as synonymous terms. A more complicated method of preparing them is described by Pliny, and in the ‘Geoponics’ (iii, 7) Sprengel says that chondrus is what is called perlgraupen by the Germans. It was therefore nearly the same as the pearl-barley of this country, only that it was prepared from the grain called spelt, triticum spelta, and not from common barley. Galen, like our author, explains that a gruel, or decoction from it, is unwholesome, as it thickens before it is properly concocted.
Starch, according to Galen and Oribasius, is lubricant, and not calefacient like bread. They say that it is not very nutritious. Serapion gives the same account of it.
Galen, Rhases, Haly Abbas, and, in fact, all the authorities, agree that barley is of a colder nature, and less nutritious than wheat. Polenta was prepared by first steeping the grain in water, and afterwards drying it at the fire, and grinding it down to meal. It was therefore a sort of malt. Galen, like our author, remarks that barley-meal sprinkled on wine and water, or water alone, makes an excellent beverage. Actuarius recommends barley-water as a diluent drink in fevers. Ptisan of barley was thus prepared: Barley was boiled until it swelled; it was then dried in the sun, and afterwards pounded and freed of its husk, and again pounded but not ground. This flour was boiled with fifteen parts of water, to which a small quantity of oil, and, when it swelled, some vinegar were added. Salt also was often added to it. It was either used as thus prepared, or it was strained, when it got the name of the juice of ptisan. (Hippocrates de Regim. in acut.; see Galen’s treatise de Ptisana.) A long-lived race of people in Chaldea are said to have subsisted principally upon barley-bread. See Lucian (Macrobii). Galen states that it is very deficient in nutritive properties. (De Re Alim. i, 10.) According to Athenæus barley-bread was among the worst kinds of it.
Galen says of oats that they are the food of horses and not of men. Aëtius and Simeon Seth call them refrigerant.
Galen, Dioscorides, Simeon Seth, and Serapion agree that rice is astringent, and recommend it for ulcers of the intestines. Galen reckons the bread prepared from it next in quality to that from wheat. Simeon Seth calls it nutritious. Celsus ranks it with things of a weak nature.
Galen and Serapion say that millet and panic being devoid of oily matter are desiccative, and therefore useful in defluxions of the belly. Simeon Seth says that the millet is of difficult digestion, and not nutritious. Rhases directs panic to be eaten with fresh milk, butter, and sugar. Pliny mentions a sweet species of bread prepared from millet. Galen says that it is not possessed of much nourishment. He says it was only used for bread in times of scarcity. The panic was merely a variety of the millet, i. e. of the panicum Italicum. It was looked upon as inferior to the common millet.
