Regimen contra pestilentiam [English] Treatise on the Pestilence.

The earliest medical work printed in English. It was published without printer's name or date, but has been attributed to the press of William Machlinia, in London, and estimated to have been published in 1483."Although often attributed in incunable editions to Benedictus Kamisius, Kamintus, Canutus or Kanuti (i.e. Bengt Knutsson, bishop of Västerâs), the author is probably Johannes Jacobi (i.e. Jean Jasme or Jacme) (Wickersheimer)" (ISTC no.  ij00013200).
