HOLY SEE/SS/SYMBOLISM
For those digging on Qs post regarding symbolism and origins based and the Holy See and the SS (Sedes Sacrorum), I have found a very good article posted in 2013 worth reading (about 10 minute read).
I have attached an easy to read pdf format in this post that removes all the ads, sidebars, and etcetera eye sores on the webpage. However for those who would prefer to go directly to the page the url is: http://humansarefree.com/2013/04/the-dark-secrets-of-vatican.html
