Question

According to a story originating in the 13th century, and disputed by the Catholic Church and many academics, who was the first (and only) female Pope?

Answer 1

Pope Joan
The first 13th century source attributed her papacy to the beginning of the 12th century, however a later 13th century writer attributed it to mid 9th century. Neither date, or the accuracy of the story as a whole, is currently accepted by a range of academics.
