About the contagious nature of the epidemic there could be no doubt. "It has been proved," wrote Covino, "that when it once entered a house scarcely one of those who dwelt in it escaped." The contagion was so great that one sick person, so to speak, would "infect the whole world." "A touch, even a breath, was sufficient to transmit the malady." Those who were obliged to render ordinary assistance to the sick fell victims. "It happened also that priests, those sacred physicians of souls, were seized by the plague whilst administering spiritual aid; and often by a single touch, or a single breath of the plague-stricken, they perished even before the sick person they had come to assist." Clothes were justly regarded as infected, and even the furniture of houses attacked was suspected. At Montpellier, at the time of the visitation, the writer says there were more doctors than elsewhere, but hardly one escaped the infection, and this even although it was recognised that medical skill was of little or no avail. According to the experience of this Montpellier doctor the mortality was greatest among the poor, because their hard lives and their poverty rendered them more susceptible to the deadly infection, and their condition did not enable them to combat it with the chances of success possessed by the well-to-do classes. As to the extent of [p037] the mortality, he says "that the number of those swept away was greater than those left alive; cities are now (_i.e._, 1350) depopulated, thousands of houses are locked up, thousands stand with their doors wide open, their owners and those who dwelt in them having been swept away." Lastly, this writer bears testimony to the baneful effect the scourge had upon the morals of those who had been spared. Such visitations, he thinks, must always exercise the most lowering influence upon the general virtue of the world.[52] From Marseilles the epidemic quickly spread northwards up the Rhone valley, and in a westerly direction through Languedoc. Montpellier, too, quickly passed on the infection. It commenced at Narbonne in the first week of Lent, 1348, and is said to have carried off 30,000 of the inhabitants. Indeed, so fearful was the visitation, that this ancient city is reported never to have recovered from the desolation it caused.[53]
