Sculpted by the Milanese sculptor Camillo Rusconi from White Marble between 1715 & 1723. The monument represents the Pope giving his blessing, on top of an urn bearing a relief showing the promulgation of the Gregorian calendar in 1582, when October 4th was followed by October 15th and he became the man who made time travel.
It's interesting that a statue celebrating the creation of a more accurate calendar would feature a dragon. It's somewhat amazing that walk through St. Peter's Basilica and you pass by the statue, marvel at it's size and beauty and then later found out what it celebrates. On the other hand, while I went through St. Peter's Basilica with a tour group and someone explaining what everything was, I kind of ditched them so I could take more pictures away from the crowds.
