In the Vatican museum there is a wooden chair with a large central hole. Also english monarchs used to have a chair like that for someone after. . I'll wipe their ass. But according to legend, this Vatican sedia was to check the masculinity of the pope chosen after the history of the papisa Joan in the middle of the ninth century. Much has been written about this, but nothing official. The Papisa Juana would come to coincide with the period of Benedict III who would die in 858.
