He next tells us of the adamantis,[392] a plant grown in Armenia and Cappadocia: presented to a lion, he says, the beast will fall upon its back, and drop its jaws. Its name originates in the fact that it is impossible to bruise it. The arianis,[393] he says, is found in the country of the Ariani; it is of a fiery colour, and is gathered when the sun is in Leo. Wood rubbed with oil will take fire on coming in contact with this plant. The therionarca,[394] he tells us, grows in Cappadocia and Mysia; it has the effect of striking wild beasts of all kinds with a torpor which can only be dispelled by sprinkling them with the urine of the hyæna. He speaks too of the æthiopis,[395] a plant which grows in Meroë; for which reason it is also known as the “meroïs.” In leaf it resembles the lettuce, and, taken with honied wine, it is very good for dropsy. The ophiusa,[396] which is found in Elephantine, an island also of Æthiopia, is a plant of a livid colour, and hideous to the sight. Taken by a person in drink, he says, it inspires such a horror of serpents, which his imagination continually represents as menacing him, that he commits suicide at last; hence it is that persons guilty of sacrilege are compelled to drink an infusion of it. Palm wine, he tells us, is the only thing that neutralizes its effects. The thalassægle[397] he speaks of as being found on the banks of the river Indus, from which circumstance it is also known as the potamaugis.[398] Taken in drink it produces a delirium,[399] which presents to the fancy visions of a most extraordinary nature. The theangelis,[400] he says, grows upon Mount Libanus in Syria, upon the chain of mountains called Dicte in Crete, and at Babylon and Susa in Persis. An infusion of it in drink, imparts powers of divination to the Magi. The gelotophyllis[401] too, is a plant found in Bactriana, and on the banks of the Borysthenes. Taken internally with myrrh and wine, all sorts of visionary forms present themselves, and excite the most immoderate laughter, which can only be put an end to by taking kernels of the pine-nut, with pepper and honey, in palm wine.
