CHAP. 10.—THE PÆONIA, PENTOROBUS, OR GLYCYSIDE: ONE REMEDY. The plant known as “pæonia”[557] is the most ancient of them all. It still retains the name[558] of him who was the first to discover it, being known also as the “pentorobus”[559] by some, and the “glycyside”[560] by others; indeed, this is one of the great difficulties attendant on forming an accurate knowledge of plants, that the same object has different names in different districts. It grows in umbrageous mountain localities, and puts forth a stem amid the leaves, some four fingers in height, at the summit of which are four or five heads resembling Greek nuts[561] in appearance; enclosed in which, there is a considerable quantity of seed of a red or black colour. This plant is a preservative against the illusions[562] practised by the Fauni in sleep. It is generally recommended to take it up at night; for if the wood-pecker[563] of Mars should perceive a person doing so, it will immediately attack his eyes in defence of the plant. CHAP. 11.—THE PANACES ASCLEPION: TWO REMEDIES. The panaces, by its very name,[564] gives assurance of a remedy for all diseases: there are numerous kinds of it, and the discovery of its properties has been attributed to the gods. One of these kinds is known by the additional name of “asclepion,”[565] in commemoration of the circumstance that Æsculapius gave the name of Panacia[566] to his daughter. The juice of it, as we have had occasion to remark already,[567] coagulates like that of fennel-giant; the root is covered with a thick rind of a salt flavour. After this plant has been taken up, it is a point religiously observed to fill the hole with various kinds of grain, a sort of expiation, as it were, to the earth. We have already[568] stated, when speaking of the exotic productions, where and in what manner this juice is prepared, and what kind is the most esteemed. That which is imported from Macedonia is known as “bucolicon,” from the fact that the neatherds there are in the habit of collecting it as it spontaneously exudes: it evaporates, however, with the greatest rapidity. As to the other kinds, that more particularly is held in disesteem which is black and soft, such being a proof, in fact, that it has been adulterated with wax. CHAP. 12.—THE PANACES HERACLEON: THREE REMEDIES. A second kind of panaces is known by the name of “heracleon,”[569] from the fact that it was first discovered by Hercules. Some persons, however, call it “Heracleotic origanum,” or wild origanum, from its strong resemblance to the origanum of which we have already[570] spoken: the root of it is good for nothing. CHAP. 13.—THE PANACES CHIRONION: FOUR REMEDIES.
