Did you guys know that Vatican City is built on a burial ground and was named after a pagan goddess KNOWN AS VATICA? I was not aware of this till they named a new Pope this year and they started talking about the history of Vatican city on the news. Makes you go HMMMMM.
There's a lot of pagan history in Rome but im not sure about this claim you saw on tv. Vatican is known to mean "divining serpent".
Vati - divining
can - serpent
This is also why the papal crest is a winged serpent.
