Sinopis[1868] was discovered in Pontus; and hence its name, from the city of Sinope there. It is produced also in Egypt, the Balearic islands, and Africa; but the best is found in Lemnos and Cappadocia, being extracted from quarries there. That part is considered the best which has been found adhering to the rock. In the native mass, it has its own proper colour within, but is spotted on the exterior; the ancients made use of it for tone.[1869] There are three kinds of sinopis, the red, the pale red, and the intermediate. The price of the best is twelve denarii per pound; it is used both for painting with the brush, and for colouring wood. The kind which comes from Africa sells at eight asses per pound; the name given to it is “cicerculum.”[1870] That[1871] which is of the deepest red is the most in use for colouring compartitions. The sinopis known as the dull[1872] kind, being of a very tawny complexion, sells also at the price of eight asses per pound; it is used principally for the lower[1873] parts of compartitions. Used medicinally, sinopis is of a soothing nature, and is employed as an ingredient in plasters and emollient poultices. It admits of being easily used, whether in the form of a dry or of a liquid composition, for the cure of ulcers situate in the humid parts of the body, the mouth and the rectum, for instance. Used as an injection, it arrests looseness of the bowels, and, taken in doses of one denarius, it acts as a check upon female discharges. Applied in a burnt state, with wine in particular, it has a desiccative effect upon granulations of the eyelids. CHAP. 14.—RUBRICA; LEMNIAN EARTH: FOUR REMEDIES. Some persons have wished to make out that sinopis is nothing else but a kind of rubrica[1874] of second-rate quality, looking upon earth of Lemnos as a rubrics of the highest quality. This last approaches very nearly to minium,[1875] and was as highly esteemed among the ancients as the island that produces it: it was never sold except in sealed packages, a circumstance to which it was indebted for its additional name of “sphragis.” It is with this material that they give the under-coating to minium, in the adulteration of which it is also extensively employed. In medicine it is very highly esteemed. Applied to the eyes in the form of a liniment, it allays defluxions and pains in those organs, and arrests the discharges from lachrymal fistulas. To persons vomiting blood, it is administered with vinegar to drink. It is taken also internally for affections of the spleen and kidneys; and by females for the purpose of arresting flooding. It is employed too, to counteract the effects of poisons, and of stings inflicted by sea or land serpents; hence it is that it is so commonly used as an ingredient in antidotes.
