The death of a well-known personage, Ammonio, the Latin secretary of the king, is the subject of several letters, including one of the 19th August from More to Erasmus; he died at nine on the morning of the 17th August, after an illness of twenty hours: he had been congratulating himself on being safe by reason of his temperate life. More confirms the statement as to deaths in the university of Oxford, and he adds also at Cambridge. In London the sweat attacks whole families: “I assure you there is less danger in the ranks of war than in this city.” His own family (? in Bucklersbury) are safe so far, and he has composed his mind for any eventuality. He hears that the sweat is now at Calais. On the 27th August, the Venetian envoy writes again that the disease is now making great progress; the king keeps out of the way at Windsor, with only three favourite gentlemen and Dionysius Memo, who is described as his physician, but in other letters as “the Reverend,” and as a musician from Venice. On the 21st September the envoy has gone to the country to avoid “the plague _and_ the sweating sickness.” A few days later (26th Sept.) he writes that “the plague” is making some progress, and that the prolonged absence of the king, the cardinal and other lords from London owing to the sweat, had encouraged the citizens to a turbulent mood against the foreign traders and residents; the state of matters was so threatening that three thousand citizens were under arms to preserve the peace. The references after September, 1517, are mostly to the “common infection” or plague, which was an almost annual autumnal event in London. There was probably some confusion, at the time, between that infection and the sweat, not, of course as regards symptoms, but in common report; thus it is not clear whether the fresh alarm in the king’s court at or near Windsor on the 15th October, owing to the deaths of young lord Grey de Wilton and a German attendant of the king, refers to the sweat or to the plague. As late as the 2nd November, a letter from the University of Oxford to Wolsey excuses delay in answering his two letters on the ground of the sweating sickness. The prevalence of “sudor tabificus” at Oxford in 1517 is known from other sources as well: it is said to have caused “the dispersion and sweeping away of most, if not all, of the students[498];” and the nuncio, writing from London on the 6th of August, mentions the current but improbable statement that more than four hundred students had died in less than a week.
