While there was probably some advance when the saints of the church took the place of the zodiacal constellations in the government of the human body, the church prevented the development along scientific lines, although there were many ramifications of saintly influence. Not the least among these was the healing efficacy of holy wells, pools, and streams, which had been empowered in some way by the saints. In some cases the bones of holy men have been buried in different parts of the continent, and after a certain lapse of time, water was said to have oozed from them, which soon formed a spring and cured all the diseases of the faithful. Perhaps the cure of leprous Naaman by bathing in the Jordan, and the restoration of the sight of the blind man by washing in the Pool of Siloam may have served as examples which the credulous were only too ready to follow. We must also note, however, as a reason for their use, that in classical times the greater number of thermal waters, more frequently used then than in the present day, remained consecrated to the gods, to Apollo, to AEsculapius, and, above all, to Hercules, who was named Iatricos, or the able physician. At any rate, many wells and fountains were dedicated to different saints, and various rites were performed there at Easter and other particular days, where offerings were also made to the saints. In Ireland, many such sacred places have been visited by the sick for centuries, and England and Scotland have them also. Not only in the British Isles, but in all parts of Europe they were much frequented in the Middle Ages, and they are not without their visitors to-day. As late as 1805 the eminent Roman Catholic prelate, Dr. John Milner, gave a detailed account of a miraculous cure performed at a sacred well in Flintshire. Gregory of Tours was one of the first to notice the healing power of springs in connection with the saints. He asserted that the diseases of the sick and infirm were banished upon the contact of a few drops of water drawn from a spring dug by St. Martin's own hands.
