Nearly approaching to the nature of sulphur is that of bitumen,[2251] which in some places assumes the form of a slime, and in others that of an earth; a slime, thrown up, as already[2252] stated, by a certain lake in Judæa, and an earth, found in the vicinity of Sidon, a maritime town of Syria. In both these states, it admits of being thickened and condensed. There is also a liquid[2253] bitumen, that of Zacynthus, for example, and the bitumen that is imported from Babylon; which last kind is also white: the bitumen, too, of Apollonia is liquid. All these kinds, in Greek, have the one general name of “pissasphaltos,”[2254] from their strong resemblance to a compound of pitch and bitumen. There is also found an unctuous liquid bitumen, resembling oil, in a spring at Agrigentum, in Sicily, the waters of which are tainted by it. The inhabitants of the spot collect it on the panicles of reeds, to which it very readily adheres, and make use of it for burning in lamps, as a substitute for oil, as also for the cure of itch-scab in beasts of burden. Some authorities include among the bitumens, naphtha, a substance which we have already mentioned in the Second Book;[2255] but the burning properties which it possesses, and its susceptibility of igniting, render it quite unfit for use. Bitumen, to be of good quality, should be extremely brilliant, heavy, and massive; it should also be moderately smooth, it being very much the practice to adulterate it with pitch. Its medicinal properties are similar to those of sulphur, it being naturally astringent, dispersive, contractive, and agglutinating: ignited, it drives away serpents by the smell. Babylonian bitumen is very efficacious, it is said, for the cure of cataract and albugo, as also of leprosy, lichens, and pruriginous affections. Bitumen is employed, too, in the form of a liniment, for gout; and every variety of it is useful for making bandolines for eye-lashes that are refractory and impede the sight. Applied topically with nitre,[2256] it is curative of tooth-ache, and, taken internally, with wine, it alleviates chronic coughs and difficulty of respiration. It is administered in a similar manner for dysentery, and is very good for arresting looseness of the bowels. Taken internally with vinegar, it dissolves and brings away coagulated blood. It modifies pains also in the loins and joints, and, applied with barley-meal, it forms a peculiar kind of plaster, to which it has given its name.[2257] It stanches blood also, heals wounds, and unites the sinews when severed. Bitumen is administered for quartan fevers, in doses of one drachma to an equal quantity of hedyosmos,[2258] the whole kneaded up with one obolus of myrrh. The smell of burnt bitumen detects a tendency to epilepsy, and, applied to the nostrils with wine and castoreum,[2259] it dispels suffocations of the uterus. Employed as a fumigation, it acts as a check upon procidence of the uterus, and, taken internally
