Looks like the ring goes back further than the seventh century.
At the left is a tablet from the early 9th century B.C. which depicts the Babylonian sun-god Shamash seated on the right, holding emblems of his authority, a staff and ring, and the king with two attendants on the left. In the center, on an altar, is a large 4-point sun image, with additional small wavy rays between the points. Clicking on the image will take you to the British Museum, where you can see and read about this tablet depicting the sun god, Shamash.
The miter is the proper liturgical headdress fir all bishops of the Latin rite, including the pope. The word comes from the Greek word mitra, meaning "turban."
The 'mitre' doesn't look like any turban, I've seen. It more closely resembles the head gear of the pagan priests of Dagon!
It consists of two stiffened flaps of material joined by a headband with two fringed strips hanging from the back base of the miter.
Those stiffened flaps are called 'lappets'. They too trace back to the pagans sun worsippers.
The miter as we know it today developed from the conical head-covering worn by the pope that appeared in the tenth century.
More likely the mitre developed from the conical fish head hat of Dagon priests. The mitre looks more like that fish head hat, then it does a 'turban'!
The Pope also has a ring and staff of authority, remarkably similar to the depiction of the sun god Shamash on the Babylonian tablet shown previously.
Note the lower hand of King Ashur-nasir-pal II in the above stele. On the wrist is the sunburst symbol. On the right, the pagan sunburst is on the glove of Pope John XXIII. Clicking on the image of the stele will take you to the British Museum.
The depictions of the pagan kings on the ancient standing stones (stela) above, show a strip of cloth (lappet) hanging from the rear of the headgear. These lappets are also present on the papal mitre and tiara, shown at left, and partially visible in the photos of popes above.
The RCC/Popes seem to have borrowed a lot of 'symbols' from the pagans, but then again they were trying to entice pagan sun worshippers to join christianity, though it looks more like chrisitanity adopted the pagan symbols. They didn't christianize Rome, they merely paganized/hellenized christianity.
Rev 17:5 And upon her forehead was a name written, MYSTERY, BABYLON THE GREAT, THE MOTHER OF HARLOTS AND ABOMINATIONS OF THE EARTH.
There is only one self-proclaimed "Mother" church, The Universal (Catholic) Church.
Rev 17:4 And the woman was arrayed in purple and scarlet colour, and decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication:
Rev 18:3 For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies.
In the Old Testament 'fornication' is often used to denote those that whored after other gods.
I think the 'cup of abominations' is all the pagan stuff that the 'church' whored after, and the merging of Sun worship. The pagans believed in eating and drinking the blood of their gods so as to become more god-like. Today, I think that is called the 'eucharist'.
The Greek Alexandrian Jews allowed some of their pagan agendas to seep into their version of the Greek Septuagint. Later, the NT would include others, like the eating and drinking of blood.
Because we pagan Catholics worship the Fish God we are, (Canon Law #666)required to eat fish every Thanksgiving. You are prolly a real Christian and so you get to eat Turkey and what not.
In honor of the Fish God, you eat fish on Fridays during Lent, do you not????? LOL Just another example of pagans eating their god/fish.
