“Turquoise” has been written in a remarkable number of ways, amongst them being turky, torkey, turquay, turkey stone, turkie, turkeis, turkese, turkise, turkes, turkas, turkis (as used by Tennyson), turkoise, turkez, turqueis, turques, turchis, turquesse, torchas, turcasse, turquez, toorkes, turkesse. The Venetians call it turchesa, the French turquoise, the Germans turkis. Andrea Bacci (“De Gemmis et Lapidibus pretiosis,” etc., 1605) says that this stone is called Turcicus, “Either on account of its admirable loveliness or for the reason that it is obtained from the Turks.” The name as we have it does not seem to go further back than the 13th century when Saxo, agreeing with Albertus Magnus, writes of it and praises its virtues as a preventive of accidents to the eye. The old Persians called it PIRUZEH, the Triumphant, and the Arabians, whose special luck stone the turquoise is, engrave on specimens the name “Allah” with a verse from the Koran, or with some magical sign inserted in pure gold. It is known to the Mexicans as CHALCHIHUITL. This stone is identified with the Callais of Pliny, who relates symbolically that it was shot down by means of slings from unapproachable rock lands.

The turquoise is favoured by Eastern occult students who employ it largely in the composition of amulets and charms. It was said to have sprung up like an eye from its matrix, and is identified with the Antares in the Archer of the Heavens. These stars were indicated as affecting the eyes in the same degree as the Pleiades and the Asselli of Taurus and Leo. In modern Egypt a turquoise is applied to the eye as a remedy for cataract and other ophthalmic troubles, specimens thus employed being usually engraved with the sacred name of Allah. The turquoise is especially the stone of horses, mules and camels, and from most ancient times specimens have adorned their trappings. Leonardus said that so long as a horseman carried a piece of turquoise with him whilst riding he would never have an accident, nor would his horse be fatigued, for it was believed that the stone would draw the pain of the accident to itself. Boetius de Boodt says that when riding to his house along an uncertain road on a dark night he fell with his horse down a declivity but neither he nor his animal suffered hurt. His turquoise, however, was shattered. The stone was carried by jockeys, huntsmen and horsemen generally as a symbol of the special protection of Jupiter. In the Middle Ages the turquoise was much worn by young girls who regarded it as a religious jewel for the protection of their virtue and for the uplifting of their thoughts. In the most ancient science the sign Sagittarius—the house or mansion of the planet Jupiter—is the sign of sport, horses, dreams, high philosophy, religion (not in the sense of
