The agreement of contemporary and later writers, shews that the published views of the most celebrated physicians of the 14th century, were those generally adopted. Among these, Chalin de Vinario is the most experienced. Though devoted to astrology, still more than his distinguished contemporary, he acknowledges the great power of terrestrial influences, and expresses himself very sensibly on the indisputable doctrine of contagion, endeavouring thereby to apologize for many surgeons and physicians of his time, who neglected their duty[181]. He asserted boldly, and with truth, “_that all epidemic diseases might become contagious[182], and all fevers epidemic_,” which attentive observers of all subsequent ages have confirmed. He delivered his sentiments on blood-letting with sagacity, as an experienced physician; yet he was unable, as may be imagined, to moderate the desire for bleeding shewn by the ignorant monks. He was averse to draw blood from the veins of patients under fourteen years of age; but counteracted inflammatory excitement in them by cupping; and endeavoured to moderate the inflammation of the tumid glands by leeches[183]. Most of those who were bled, died; he therefore reserved this remedy for the plethoric; especially for the papal courtiers, and the hypocritical priests, whom he saw gratifying their sensual desires, and imitating Epicurus, whilst they pompously pretended to follow Christ[184]. He recommended burning the boils with a red-hot iron, only in the plague without fever, which occurred in single cases[185]; and was always ready to correct those over-hasty surgeons, who, with fire and violent remedies, did irremediable injury to their patients[186]. Michael Savonarola, professor in Ferrara (1462), reasoning on the susceptibility of the human frame to the influence of pestilential infection, as the cause of such various modifications of disease, expresses himself as a modern physician would on this point; and an adoption of the principle of contagion was the foundation of his definition of the plague[187]. No less worthy of observation are the views of the celebrated Valescus of Taranta, who, during the final visitation of the Black Death, in 1382, practised as a physician at Montpellier, and handed down to posterity what has been repeated in innumerable treatises on plague, which were written during the 15th and 16th centuries[188].
