Evaluation of Example 15: The Egyptian Dragon Jasper Amulet

Passage:

Described amulet similar to Chrysoprase Chnobis, Budapest Museum of Fine Arts. Photo: László Mátyus in David Frankfurter, 'Guide to the Study of Ancient Magic' (Brill, 2009), 449. “Galen mentions an amulet belonging to an Egyptian king, who is said to have lived 630 B.C. It was composed of a green jasper cut in the form of a dragon, and surrounded with rays. This was applied to strengthen the stomach and organs of digestion.”

Analsyis:

Galen, noted ancient Green physician, advised patients to hang a green stone jade amulet (with or without an engraving of the image of Chnoubis, the destroyer of demons) near an ailment for its curative effects. The use of jasper amulets were part of medical practice from the time of the ancient Egyptian physicians. This quoted passage does not commit a fallacy per se since it is not an argument. But the medical practice of the use of an green jasper stone, itself, is based on a supposition of the false cause that green jasper is an effective remedy in the healing arts. Historically, there is no evidence that the use of jade (or the image of Chnoubis, the destroyer of demons) was effective for the variety of treatments for which it was prescribed.
