Some physicians, in their experiments with chemistry, probably dabbled in alchemy also, but this branch of the magical arts had in general very little currency among Jews. Steinschneider says that "Hebrew literature contains remarkably little material on this subject"; I have not found any reference to or directions for the practice of alchemy in the literary works produced in Northern Europe, although Jews were popularly believed to be adepts. See G. Scholem, "Alchemie and Kabbala," MGWJ, LXIX (1925), 13-20, 95-110, 371-4, and LXX (1926), 202-9; R. Eisler, "Zur Terminologie u. Geschichte der jüd.

cf. Jacobs, Jews of Angevin England, 153;G. Caro, I, 136; S. Ḥas. 1352. Speaking of relics, it is related that "once a Gentile produced a shirt which he claimed had been worn by Jesus. 'If you don't believe me, just watch!' and he threw the shirt into a fire, but it didn't burn. The priests and monks turned to the Jews who were present and challenged them, 'Now you know that this shirt is holy.' But a Jew stepped forward with, 'Here, give it to me and I'll show you what it's all about.' Using strong vinegar and soap he scrubbed it vigorously before their eyes and then returned it, saying, 'Now throw it in the fire and see what happens.' They did so and it was instantly consumed. He then explained, 'It was smeared with a salamander extract which I washed off'" (S. Ḥas. 1809). The belief that the salamander was invulnerable to fire was very widespread in the Middle Ages, cf. Ginzberg, Legends, V, 52, n. 157, 158.
