In the twelfth century, the Bishop of Rennes lavishes encomiums upon this beautiful stone. It is quite natural that this writer should lay especial stress upon the use of the sapphire for the adornment of rings, for it was in his time that it was beginning to be regarded as the stone most appropriate for ecclesiastical rings. The sapphire was like the pure sky, and mighty Nature had endowed it with so great a power that it might be called sacred and the gem of gems. Fraud was banished from its presence and necromancers honored it more than any other stone, for it enabled them to hear and to understand the obscurest oracles.[150]

The traditional virtue of the sapphire as an antidote against poison is noted by Bartolomæus Anglicus, who claims to have seen a test of its power, somewhat similar to that recorded by Ahmed Teifashi of the emerald. In John of Trevisa’s version this passage reads as follows:[151]
His vertue is contrary to venym, and quencheth it every deale. And yf you put an attercoppe[152] in a boxe and hold a very saphyre of Inde at the mouth of the boxe ony whyle, by vertue thereof the attercoppe is overcome & dyeth as it were sodenly, as Dyasc. sayth [pseudo Dioscorides]. And this same I have assayed oft in many and dyvers places. His vertue kepeth and savyth the syght, & clearyth eyen of fylthe wythout ony greyf.
Voicing the general belief that the sapphire was endowed with power to influence spirits, Bartolomæus says that this stone was a great favorite with those who practised necromancy, and he adds: “Also wytches love well this stone, for they wene that they may werke certen wondres by vertue of this stone.”[153]
There was in the South Kensington Museum, in London, a splendid sapphire of a peculiar tint. In the daylight it shows a beautiful rich blue color, while by artificial light it has a violet hue and resembles an amethyst. In the eighteenth century this stone was in the collection of Count de Walicki, a Polish nobleman, and Mme. de Genlis used it as the theme of one of her stories, entitled “Le Saphire Merveilleux.” Here the sapphire is used as a test of female virtue, the change of color indicating unfaithfulness on the part of the wearer. If the owner of the stone wished to prove that the subject of the test was innocent, she was made to wear the sapphire for three hours of daylight; but in the opposite case the test was so timed that it began in daylight and ended when the candles or lamps had been lighted. This sapphire, still known as the “Saphire Merveilleux,” was for a time in the collection of the Duke of Orleans, who bore the name of Philippe Egalité during the French Revolution.
