Arabia, too, produces sugar;[474] but that of India is the most esteemed. This substance is a kind of honey, which collects in reeds, white, like gum, and brittle to the teeth. The larger pieces are about the size of a filbert; it is only employed, however, in medicine.
CHAP. 18.—TREES OF ARIANA, GEDROSIA, AND HYRCANIA.
On the frontiers of India is a country called Ariana, which produces a thorny shrub,[475] rendered precious by the tears which it distils. It bears some resemblance to myrrh, but is very difficult of access, by reason of the thorns with which it is armed. Here, too, a poisonous shrub is found, with a root like the radish,[476] and leaves like those of the laurel. By its powerful odour it attracts horses, and was very nearly depriving Alexander of all his cavalry upon his first arrival there, an accident which also happened in Gedrosia. A thorny shrub[477] has been also spoken of as a native of the same country, with leaves like those of the laurel, the juice of which, if sprinkled upon the eyes, is productive of blindness in all animals. Another plant is also mentioned, with a most remarkable odour, and full of diminutive serpents,[478] the sting of which is sure to cause instant death. Onesicritus states, that in the vallies of Hyrcania, there is a tree resembling the fig, and known as the occhus,[479] from which a honey distils for two hours every morning.
CHAP. 19. (9.)—TREES OF BACTRIANA, BDELLIUM, OR BROCHON, OTHERWISE MALACHA, OR MALDACON, SCORDASTUM. ADULTERATIONS USED IN ALL SPICES AND AROMATICS; THE VARIOUS TESTS OF THEM AND THEIR RESPECTIVE VALUES.
In the vicinity, too, of India, is Bactriana, in which region we find bdellium,[480] that is so highly esteemed. This tree is of a black colour, and about the size of the olive; it has leaves like those of the robur, and bears a fruit similar to that of the wild fig, and in nature resembling a kind of gum. This fruit is by some persons called brochon, by others malacha, and by others, again, maldacon. When of a black colour, and rolled up in cakes, it bears the name of hadrobolon. This substance ought to be transparent and the colour of wax, odoriferous, unctuous when subjected to friction, and bitter to the taste, though without the slightest acidity. When used for sacred purposes, it is steeped in wine, upon which it emits a still more powerful odour. The tree is a native of both India and Arabia, as well as Media and Babylon; some persons give to the bdellium that is imported by way of Media, the name of peraticum.[481] This last is remarkable for its brittleness, while, at the same time, it is harder and more bitter than the other kinds; that of India, on the other hand, is moister, and gummy. This last sort is adulterated by means of almonds, while the various other kinds are falsified with the bark of scordastum, that being the name of a tree[482] the gum of which strongly resembles bdellium. These adulterations, however, are to be detected—and let it suffice to mention it here, in relation to all other perfumes as well—by the smell, the colour, the weight, the taste, and the action of fire. The bdellium of Bactriana is shining and dry, and covered with numerous white spots resembling the finger-nails; besides which, it should be of a certain weight, heavier or lighter than which it ought not to be. The price of bdellium, in its pure state, is three denarii per pound.
CHAP. 20.—TREES OF PERSIS.
Adjoining the countries which we have previously mentioned is Persis, lying along the shores of the Red Sea, which, when describing[483] it, we have mentioned as the Persian Sea, the tides of which penetrate far into the land. The trees in these regions are of a marvellous nature; for, corroded by the action of the salt, and bearing a considerable resemblance to vegetable substances that have been thrown up and abandoned by the tide, they are seen to embrace the arid sands of the sea-shore with their naked roots, just like so many polypi. When the tide rises, buffeted by the waves, there they stand, fixed and immoveable; nay, more, at high water they are completely covered; a fact which proves to conviction, that they derive their nutriment from the salt contained in the water. The size of these trees is quite marvellous; in appearance they strongly resemble the arbute; the fruit, which on the outside is very similar to the almond, has a spiral kernel within.[484]
