The deadly power of the cockatrice is alluded to by Shakspeare in ‘Twelfth Night’ and in ‘Romeo and Juliet’-- Say thou but _I_, And that base vowel _I_ shall poison more Than the death-darting eye of cockatrice. So Dryden says:-- Mischiefs are like the cockatrice’s eye; If they see first, they kill; if seen, they die-- alluding to the counter-action, that if the creature was seen by a person first, without being perceived by it, the cockatrice died from the effect of the human eye. The figure of the bird merely gave security against the evil eye; it had no other effect, and for this purpose various engraved stones were used. Thus a ring in the Londesborough Collection has in its centre a Gnostic gem with cabalistic figures, believed able to avert the dreadful glance. In the same collection is a massive thumb-ring, having the tooth of some animal as its principal gem, supposed to have mystic power over the fortunes of its possessor. It is set all round with precious stones of talismanic virtues. A dove, with a branch of olive in its mouth, engraved in pyrites, and mounted in a silver ring, ensured the wearer the utmost hospitality wherever he went, possessing the power of fascination. A fair head, well combed, with a handsome face, engraved on a gem, secured joy, reverence, and honour. Rings made of the bones of an ostrich were assumed to be of rare virtue. [Illustration: Charm-ring.] Annexed is a representation of a silver charm-ring in the South Kensington Museum; the hoop is spirally fluted, widening towards the bezel, which is set with a tooth; the shoulder of the ring is pierced in floriated German work of the eighteenth century. In the Waterton Collection are several rings of hoof--probably that of an ass--enclosed in gold, and considered a remedy for epilepsy. From Cardan (de Venenis) we learn, among other means for a physician to find out whether a patient is ‘fascinated,’ that of a ring made of the hoof of an ass, put on his finger, growing too large for him after a few days’ wearing. It seems that among the Indians and Norwegians the hoof of the elk is regarded as a sovereign cure for the same malady. The person afflicted applies it to his heart, holding it in his left hand, and rubbing his ear with it. Brand, in his ‘Popular Antiquities,’ states that in Berkshire a ring made from a piece of silver collected at the Communion is supposed to be a cure for convulsions and fits of every kind. If collected on Easter Sunday its efficacy is greatly increased. Silver is not considered necessary in Devonshire, where a ring is preferred made out of three nails or screws that have been used to fasten a coffin, and that have been dug out of the churchyard. It is curious to notice that, according to Pliny, the ancients believed that a nail drawn out of a sepulchre and placed on the threshold of a bed-chamber door would drive away phantoms in the night.
