Ibidem passio sancti Petri Martyris, qui, cum esset cubicularius Diocletiani Imperatoris, et liberius de immensis Martyrum suppliciis quereretur, propterea, jubente eodem, in medium adducitur, ac primo suspensus, diutissime flagris torquetur, deinde aceto ac sale perfusus, ad ultimum in craticula lento igne assatur, sicque vere Petri exstitit et fidei heres et nominis.
