The water which had been used before Easter to clean the altar of the saints was also considered to be a famous remedy. If such water was employed in washing a patient he recovered at once, and this was the happy experience of Countess Eborin. This exhalted patient was suffering so severely that she believed her hour had come. She was then quickly removed to the church of St. Martin, and thoroughly washed with the water that had been used in washing the altar. And, behold! the disease disappeared, and let us hope that the overjoyed countess afterward enjoyed many years of life. Oil from lamps hung in holy places was also a favorite remedy, but it appears that it was principally used for anointing. However, when mixed with holy water, it furnished a remedy which could be administered to diseased cattle with a prospect of positive cure. Water which was obtained by boiling the covers in which the relics were wrapped also yielded a very efficacious medicine. Thus, for instance, Gregory of Tours caused a silk cover, in which a piece of the cross of Christ had been wrapped, to be thoroughly boiled, and he then administered this decoction to patients; the curtains which were used as ornaments over holy graves also displayed an extremely beneficent effect upon the sick. If an individual suffering from headache touched, for instance, the carpet which was placed over the resting-place of St. Julian, the pain ceased. But if a patient was afflicted with abdominal pains, all that was necessary to relieve him at once was to pull a thread from this, the above-named carpet, and to apply it to his rebellious digestive apparatus. However, it was not necessary for the priests, under some circumstances, personally to take the trouble of manufacturing miraculous medicines from relics. There existed some holy graves which were so accommodating that they furnished, of their own accord, the holy material that was required for the treatment of the sick. Thus the chronicler records that the grave of the evangelist John exuded a sort of white manna, which, owing to its wonder-working curative power, was distributed all over the world. A similar product was yielded by the grave of the Apostle Andrew on the festival day of that saint. A precious oil scented like nectar also sprang from the resting-place of this man of God. We see, therefore, that the sacred pharmacopœia teemed with remedies, and that they were quite extensively employed is shown sufficiently by the history of the saints and, above all, by the works of Gregory of Tours. The latter, in particular, offer an actually inexhaustible mine of information concerning the medical activity of Christian saints.
