An oil is made, too, from the citrus,[1703] and from the cypress; also, from the walnut,[1704] and known by the name of “caryinon,”[1705] and from the fruit of the cedar, being generally known as “pisselæon.”[1706] Oil is extracted from the grain of Cnidos,[1707] the seed being first thoroughly cleaned, and then pounded; and from mastich[1708] also. As to the oil called “cyprinum,”[1709] and that extracted from the Egyptian[1710] berry, we have already mentioned the mode in which they are prepared as perfumes. The Indians, too, are said to extract oils from the chesnut,[1711] sesamum, and rice,[1712] and the Ichthyophagi[1713] from fish. Scarcity of oil for the supply of lamps sometimes compels us to make it from the berries[1714] of the plane-tree, which are first steeped in salt and water. Œnanthinum,[1715] again, is made from the œnanthe, as we have already stated when speaking of perfumes. In making gleucinum,[1716] must is boiled with olive-oil at a slow heat; some persons, however, do not employ fire in making it, but leave a vessel, filled with oil and must, surrounded with grape husks, for two and twenty days, taking care to stir it twice a day: by the end of that period the whole of the must is imbibed by the oil. Some persons mix with this not only sampsuchum, but perfumes of still greater price: that, too, which is used in the gymnasia is scented with perfumes as well, but those of the very lowest quality. Oils are made, too, from aspalathus,[1717] from calamus,[1718] balsamum,[1719] cardamum,[1720] melilot, Gallic nard, panax,[1721] sampsuchum,[1722] helenium, and root of cinnamomum,[1723] the plants being first left to steep in oil, and then pressed. In a similar manner, too, rhodinum[1724] is made from roses, and juncinum from the sweet rush, bearing a remarkable[1725] resemblance to rose-oil: other oils, again, are extracted from henbane,[1726] lupines,[1727] and narcissus. Great quantities of oil are made in Egypt, too, of radish[1728] seed, or else of a common grass known there as chortinon.[1729] Sesamum[1730] also yields an oil, and so does the nettle,[1731] its oil being known as “cnidinum.”[1732] In other countries, too, an oil is extracted from lilies[1733] left to steep in the open air, and subjected to the influence of the sun, moon, and frosts. On the borders of Cappadocia and Galatia, they make an oil from the herbs of the country, known as “Selgicum,”[1734] remarkably useful for strengthening the tendons, similar, in fact, to that of Iguvium[1735] in Italy. From pitch an oil[1736] is extracted, that is known as “pissinum” it is made by boiling the pitch, and spreading fleeces over the vessels to catch the steam, and then wringing them out: the most approved kind is that which comes from Bruttium, the pitch of that country being remarkably rich and resinous: the colour of this oil is yellow.
