Chrysoprase

Wonderful things are told of the virtue of the chrysoprase, for Volmar states that, if a thief sentenced to be hanged or beheaded should place this stone in his mouth, he would immediately escape from his executioners.[69] Although we are not informed in what way this fortunate result was attained, it seems likely that the stone was believed to make the thief invisible, and thus possessed a virtue often attributed to the opal.

A strange story regarding a magic stone reputed to have been worn by Alexander the Great is related by Albertus Magnus. According to this recital, Alexander, in his battles, wore a “prase” in his girdle. On his return from his Indian campaign, wishing one day to bathe in the Euphrates, he laid aside his girdle, and a serpent bit off the stone and then dropped it into the river.[70] Even Albertus, who is far from critical, admits that the story seems like a fable, and it probably belongs to a comparatively late period. As the term “prase” is used very loosely by early writers, this “victory stone” may have been an emerald or possibly jade.
