So much so, that whenargued in 1647 that it was a legend he was criticized by fellow Protestants. The story has it that a scholarly woman, disguised as a man, succeeded to the chair of Peter about 1100 (later versions state 855).

It seems that a thirteenth-century Dominican chronicler, Jean de Mailly, first gave respectability to the legend and that it gained wide currency in the , partly due to the influence of Martinus Polonus (d.1278) and the use of the story in fifteenth- century controversies over the extent of papal power. Some scholars interpret the story as a modification of a Roman folk- story, the original possibly relating to a priest of Mithra and a child.
