Note 36 — The Third Book.

From the Mirror of Stones I extract a few specimens of the absurd ideas once prevalent respecting precious stones.

The Amethyst drives away drunkenness; for being bound on the navel, it restrains the vapour of the wine, and so disolves the ebriety.

Alectoria is a stone of a christalline colour, a little darkish, somewhat resembling limpid water; and sometimes it has veins of the colour of flesh. Some call it Gallinaceus, from the place of its generation, the intestines of capons, which were castrated at three years old, and had lived seven, before which time the stone ought not to be taken out, for the older it is, so much the better. When the stone is become perfect in the Capon, he do’nt drink. However tis never found bigger than a large bean. The virtue of this stone is to render him who carries it invisible, being held in the mouth it allays thirst, and therefore is proper for wrestlers; makes a woman agreable to her husband; bestows honors and preserves those already acquired; it frees such as are bewitched; it renders a man eloquent, constant, agreable and amiable; it helps to regain a lost Kingdom, and acquire a foreign one.

Borax, Nosa, Crapondinus, are names of the same stone, which is extracted from a toad. There are two species; that which is the best is rarely found; the other is black or dun with a cerluean glow, having in the middle the similitude of an eye, and must be taken out while the dead toad is yet panting, and these are better than those which are extracted from it after a long continuance in the ground. They have a wonderful efficacy in poisons. For whoever has taken poison, let him swallow this; which being down, rolls about the bowels, and drives out every poisonous quality that is lodged in the intestines, and then passes thro’ the fundament, and is preserved.

Corvia or Corvina, is a Stone of a reddish colour, and accounted artificial. On the calends of April boil the eggs taken out of a Crow’s nest till they are hard: and being cold let them be placed in the nest as they were before. When the crow knows this, she flies a long way to find the stone, and having found it returns to the nest, and the eggs being touched with it, they become fresh and prolific, the Stone must immediately be snatched out of the nest, its virtue is to increase riches, to bestow honors, and to foretell many future events.

Kinocetus is a stone not wholly useless—since it will cast out Devils
