These documents offer the precautions and rules that were set in place to hinder the number of casualties, it was to take control and keep people from spreading the plague. When the Plague originally started to spread, people in Pistoia were not able to leave the city and no one was allowed back in. This was to help maintain the spreading of the disease and protect the few people alive in the city. The Tartars took over a Christian village and the onset of plague overruled the Tartars. The understanding of the disease process was that it spreads fast, viciously and it kills a lot of people unwillingly.
