We find it stated by the most trustworthy among the Greek writers,[894] that this plant first made its appearance in the vicinity of the gardens of the Hesperides and the Greater Syrtis, immediately after the earth had been soaked on a sudden by a shower as black as pitch. This took place seven years before the foundation of the city of Cyrenæ, and in the year of Rome 143. The virtues of this remarkable fall of rain extended, it is said, over no less than four thousand stadia of the African territory; and upon this soil laserpitium began universally to grow, a plant that is in general wild and stubborn, and which, if attempted to be cultivated, will leave the spot where it has been sown quite desolate and barren. The roots of it are numerous and thick, the stalk being like that of fennel-giant, and of similar thickness. The leaves of this plant were known as “maspetum,” and bore a considerable resemblance to parsley; the seeds of it were foliaceous, and the plant shed its leaves every year. They used to feed the cattle there upon it; at first it purged them, but afterwards they would grow fat, the flesh being improved in flavour in a most surprising degree. After the fall of the leaf, the people themselves were in the habit of eating[895] the stalk, either roasted or boiled: from the drastic effects of this diet the body was purged for the first forty days, all vicious humours being effectually removed.[896] The juices of this plant were collected two different ways, either from the root or from the stalk; in consequence of which these two varieties of the juice were known by the distinguishing names of “rhizias” and “caulias,”[897] the last being of inferior quality to the other, and very apt to turn putrid. Upon the root there was a black bark, which was extensively employed for the purposes of adulteration. The juice of the plant was received in vessels, and mixed there with a layer of bran; after which, from time to time it was shaken, till it had reached a proper state of maturity; indeed, if this precaution was neglected, it was apt to turn putrid. The signs that it had come to maturity were its colour, its dryness, and the absorption of all humidity.
