The bezoar stone, according to the usual belief, was taken from the intestines or the liver either of the goat or of the deer. The Arabs told a strange tale as to the generation of this stone.[409] They said that at certain seasons the deer were wont to devour snakes and other venomous creatures, whereupon they would straightway hasten to the nearest pool and plunge into it until only their nostrils were above the water. Here they remained until the feverish heat caused by the poison they had swallowed was alleviated. During this time stones were formed in the corners of their eyes; these dropped as the deer left the pool, and were found on its banks. The stones were a sovereign antidote for poisons of all kinds. When reduced to a powder and taken internally, or when simply bound to the injured part, they effected a cure by inducing a profuse perspiration. It is curious to note that this tale foreshadows, in a fanciful way, the latest progress of medical science; namely, the use of a substance generated in the body of a diseased animal as an antidote for the disease from which the animal suffered. We are also told that Abdallah Narach narrates the case of the Moorish king of Cordoba, Miramamolin, as Monardes gives the name, to whom a violent poison had been administered and who was cured by means of a bezoar stone. The king, overcome with gratitude for the preservation of his life, gave his royal palace to the man who had brought him the stone. Monardes remarks: “This certainly was a royal gift, since we see that at this day the castle of Cordova is something rare and of great value and the stone must have been highly prized when such a price was paid for it.”[410] [Illustration: Application of a besoar to cure a victim of poisoning. From Johannis de Cuba’s “Ortus Sanitatis,” Strassburg, 1483. ] The first mention of the bezoar stone is by the Arabic and Persian writers. In the Arabic work attributed to Aristotle, and which was certainly written as early as the ninth and possibly in the seventh century, it is even described among the precious stones. The same is true of the oldest Persian work on medicine, namely, that of Abu Mansur Muwaffak, composed about the middle of the tenth century. A valuable monograph on the bezoar was written in 1625 by Caspar Bauhin, a learned professor and physician of Basel; this work contains all that was then known of the various qualities ascribed to this substance by the older authors.
