Note 17 — THE GREAT PESTILENCE. CHAPTER I. THE COMMENCEMENT OF THE EPIDEMIC.
Reading edition
"Chi cominciavano a sputare sangue, morivano chi di subito." The contemporary chronicle of Parma by the Dominican John de Cornazano also notes the same: "Et fuit talis quod aliqui sani, si spuebant sanguinem, subito ibi moriebantur, nec erat ullum remedium" (Monumenta historica ad provincias Parmensem et Placentinam pertinentia, vol. v, p. 386).
