Tractatus de pestilentia.

The most widely disseminated of all plague tracts from the time of the Black Death, of which 33 printed editions appeared in the 15th century. A French rhymed version appeared in 1476, but this version is very different from the prose, and from the pre-printing manuscripts that are known. The plague tracts from the Black Death represent the first productions of a large-scale public health effort in Europe. ISTC No. ij00015000.
