One of the myths that have gathered around the name of Basil Valentine, because it has become a commonplace in philology, has probably made him more generally known than any of his actual discoveries. In one of the most popular of the old-fashioned text-books of chemistry in use about half a century ago, in the chapter on antimony, there was a story that students, if I may judge from my own experience, never forgot. It was said that Basil Valentine, a monk of the Middle Ages, was the discoverer of this substance. After having experimented with it in a number of ways, he threw some of it out of his laboratory one day when the swine of the monastery, finding it, proceeded to gobble it up, together with some other refuse. Just when they were finishing it, the monk discovered what they were doing. He feared the worst from it, but took the occasion to observe the effect upon the swine very carefully. He found that, after a preliminary period of digestive disturbance, these swine developed an enormous appetite, and became fatter than any of the others. This seemed a rather desirable result, and Basil Valentine, ever on the search for the practical, thought that he might use the remedy to good purpose on the members of the community. Some of the monks in the monastery were of rather frail health and delicate constitution, and most of them were rather thin, and he thought that the putting on of a little fat, provided it could be accomplished without infringement of the rule, might be a good thing for them. Accordingly, he administered, surreptitiously, some of the salts of antimony, with which he was experimenting, in the food served to these monks. The result, however, was not so favorable as in the case of the hogs. Indeed, according to one, though less authentic, version of the story, some of the poor monks, the unconscious subjects of the experiment, perished as the result of the ingestion of the antimonial compounds. According to the better version, they suffered only the usual unpleasant consequences of taking antimony, which are, however, quite enough for a fitting climax to the story. Basil Valentine called the new substance which he had discovered antimony, that is, _opposed to monks_. It might be good for hogs, but it was a form of monks' bane, as it were.[30]
