That such deadly intramural epidemics in monasteries were not impossible is conclusively proved by the authentic particulars of a sudden and severe mortality among the rich monks of Croyland at a much more recent date--between the years 1304 and 1315. In the appendix to the chronicle of Ramsey Abbey[19] there is printed a letter from Simon, abbot of Croyland, without date but falling between the years above given, addressed to his neighbours the abbots of Ramsey, Peterborough and Thorney, and the prior of Spalding. The letter is to ask their prayers on the occasion of the sudden death of thirteen of the monks of Croyland and the sickness of others; that large number of the brethren had been cut off within fifteen days--“potius violenter rapti quam fataliter resoluti[20].” The letter is written from Daddington, whither abbot Simon had doubtless gone to escape the infection. These are two instances of deadly epidemics within the walls of English monasteries. In the plague-years 664-685, and long after in the Black Death, the mortalities among the monks were of the same degree, only there was an easy explanation of them, in one if not in both cases, as being part of an imported infection universally diffused in English soil. What the nature of the occasional outbreaks in earlier times may have been, we can only guess: something almost as deadly, we may say, as the plague itself, and equally sudden. The experience was not peculiar to England. An incident at Rome almost identical with that of Vighard in 668 is related in a letter sent home in 1188, by Honorius the prior of Canterbury, who had gone with others of the abbey on a mission to Rome to obtain judgment in a dispute between the archbishop and the abbey, that the whole of his following was stricken with sickness and that five were dead. John de Bremble, who being also abroad was ordered to go to the help of the prior, wrote home to the abbey that when he reached Rome only one of the brethren was alive, and he in great danger, and that the first thing he had to do on his arrival was to attend the cook’s funeral[21].
