Cassia[561] is a shrub also, which grows not far from the plains where cinnamon is produced, but in the mountainous localities; the branches of it are, however, considerably thicker, than those of cinnamon. It is covered with a thin skin rather than a bark, and, contrary to what is the case with cinnamon, it is looked upon as the most valuable when the bark falls off and crumbles into small pieces. The shrub is three cubits in height, and the colours which it assumes are threefold: when it first shoots from the ground, for the length of a foot, it is white; after it has attained that height, it is red for half a foot, and beyond that it is black. This last is the part that is held in the highest esteem, and next to it the portion that comes next, the white part being the least valued of all. They cut the ends of the branches to the length of two fingers, and then sew them in the fresh skins of cattle that have been killed expressly for the purpose; the object being that the skins may putrefy, and the maggots generated thereby may eat away the woody parts, and so excavate[562] the bark; which is so intensely bitter, that it is quite safe from their attacks. That which is the freshest is the most highly esteemed; it has a very delicate smell, and is so extremely hot to the taste, that it may be said to burn the tongue, rather than gradually warm the mouth. It is of a purple colour, and though of considerable volume, weighs but very little in comparison; the outer coat forms into short tubes which are by no means easily broken: this choice kind of cassia, the barbarians call by the name of lada. There is another sort, again, which is called balsamodes,[563] because it has a smell like that of balsam, but it is bitter; for which reason it is more employed for medicinal purposes, just as the black cassia is used for unguents. There is no substance known that is subject to greater variations in price: the best qualities sell at fifty denarii per pound, others, again, at five.
(20.) To these varieties the dealers have added another, which they call daphnoides,[564] and give it the surname of isocinnamon;[565] the price at which it sells is three hundred denarii per pound. It is adulterated with storax, and, in consequence of the resemblance of the bark, with very small sprigs of laurel. Cassia is also planted in our[566] part of the world, and, indeed, at the extreme verge of the Empire, on the banks of the river Rhenus, where it flourishes when planted in the vicinity of hives of bees. It has not, however, that scorched colour which is produced by the excessive heat of the sun; nor has it, for the same reason, a similar smell to that which comes from the south.
CHAP. 44.—CANCAMUM AND TARUM.
From the confines of the country which produces cinnamon and cassia, cancamum[567] and tarum[568] are imported; but these substances are brought by way of the Nabatæan Troglodytæ, a colony of the Nabatæi.
CHAP. 45. (21.)—SERICHATUM AND GABALIUM.
Thither, too, are carried serichatum[569] and gabalium, aromatics which the Arabians rear for their own consumption, and which are only known by name in our part of the world, though they grow in the same country as cinnamon and cassia. Still, however, serichatum does reach us occasionally, and is employed by some persons in the manufacture of unguents. It is purchased at the rate of six denarii per pound.
CHAP. 46.—MYROBALANUM.
In the country of the Troglodytæ, the Thebais, and the parts of Arabia which separate Judæa from Egypt, myrobalanum[570] is commonly found; it is provided by Nature for unguents, as from its very name would appear. From its name, also, it is evident that it is the nut of a tree, with a leaf similar to that of the heliotropium, which we shall have to mention when speaking of the herbs. The fruit of this tree is about the size of a filbert. The kind that grows in Arabia is known as Syriaca, and is white, while, on the other hand, that which grows in the Thebais is black: the former is preferred for the quality of the oil extracted from it, though that which is produced in the Thebais yields it in larger quantities. Among these various kinds, that which is sent from the country of the Troglodytæ is the worst of all. There are some persons who prefer that of Æthiopia[571] to all of these, the nut of which is black, and not oleaginous; it has only a very small kernel, but the liquid which is extracted from it is more odoriferous than that of the other kinds; it grows, too, in a champaign, open country. It is said that the Egyptian nut is even more oleaginous, being of a reddish colour with a thicker shell, and that the plant, although it grows in wet, marshy spots, is shorter and drier than the other kinds. The Arabian nut, again, is said to be of a green colour and of smaller size, but harder and more compact, from the circumstance that it grows in mountainous districts. The best of all, however, is that of Petra, which comes from a city mentioned[572] on a previous occasion; it has a black shell, but the kernel is white. The perfumers, however, only extract the juices from the shells; but medical men pound the kernels, pouring warm water on them, little by little, as they do it.
CHAP. 47. (22.)—PHŒNICOBALANUS.
The fruit of the palm in Egypt, which is known by the name of adipsos,[573] is put to a similar use in unguents, and is held next in esteem after the myrobalanum. It is of a green colour, has exactly the smell of a quince, and has no stone or nut within. It is gathered a little before it begins to ripen. That which is left ungathered is known as phœnicobalanus;[574] it turns black, and has a tendency to inebriate the person who eats of it. The price of myrobalanum is two denarii per pound. The shop-keepers give this name also to the dregs of the unguent that is made with it.
