There is a fictitious Urban X in Voltaire's famous anti-clerical novel Candide, the supposed father of the old lady who becomes part of the group following Candide on his adventures. A Jesuit provincial in South America also figures in Candide, and Pope Francis was a Jesuit provincial earlier. So Voltaire must be spinning in his grave.
lol.... Didn’t realize that. The Xth was meant to whatever number (X=n)
