In the national archive of mexico lies a brief but significant document made by the inquisition at the end of the xviiith century. The charges were made against an anonymous professor of medicine, who declared a set of irreligious insults which injured the catholic moral of the society of the new spain. From the censorship that this text caused, a religious and folklore narrative is detected, that was part of the medicine at the second half of the xviiith century. Thereby, based on the hagiographic tradition, it is analyzed the singularity of the insults attributed to this anonymous professor of medicine. The tracing of the references is proposed in three ways of the written medical culture of the xviiith century. 1) Medical dissertations. 2) Libraries owned by physicians. 3) Works written by physicians. It is concluded that the insults uttered where not random, on the contrary, the narrative elicited in the legends of the archangel raphael, saint camil of lelis and a mexican bird represent the establishing beliefs and the ideas of the new spain's medicine in the xviiith century.
