There is nothing so much adulterated[1951] as saffron: the best proof of its goodness is when it snaps under pressure by the fingers, as though it were friable;[1952] for when it is moist, a state which it owes to being adulterated, it is limp, and will not snap asunder. Another way of testing it, again, is to apply it with the hand to the face, upon which, if good, it will be found to be slightly caustic to the face and eyes. There is a peculiar kind, too, of cultivated saffron, which is in general extremely mild, being only of middling[1953] quality; the name given to it is “dialeucon.”[1954] The saffron of Cyrenaica, again, is faulty in the opposite extreme; for it is darker than any other kind, and is apt to spoil very quickly. The best saffron everywhere is that which is of the most unctuous quality, and the filaments of which are the shortest; the worst being that which emits a musty smell. Mucianus informs us that in Lycia, at the end of seven or eight years, the saffron is transplanted into a piece of ground which has been prepared for the purpose, and that in this way it is prevented from degenerating. It is never[1955] used for chaplets, being a plant with an extremely narrow leaf, as fine almost as a hair; but it combines remarkably well with wine, sweet wine in particular. Reduced to a powder, it is used to perfume[1956] the theatres. Saffron blossoms about the setting of the Vergiliæ, for a few days[1957] only, the leaf expelling the flower. It is verdant[1958] at the time of the winter solstice, and then it is that they gather it; it is usually dried in the shade, and if in winter, all the better. The root of this plant is fleshy, and more long-lived[1959] than that of the other bulbous plants. It loves to be beaten and trodden[1960] under foot, and in fact, the worse it is treated the better it thrives: hence it is, that it grows so vigorously by the side of foot-paths and fountains. (7.) Saffron was already held in high esteem in the time of the Trojan War; at all events, Homer,[1961] we find, makes mention of these three flowers, the lotus,[1962] the saffron, and the hyacinth.
