Alright ya’ll. Here’s what I have so far. PATERNOSTER+OPQRD

P	A	T	E	R	N	O	S	T	E	R
A	 	 	 	 	 	 	 	 	 	E
T	 	 	 	D	 	P	 	 	 	T
E	 	 	 	 	 	 	 	 	 	S
R	 	D	 	R	 	Q	 	P	 	O
N	 	 	 	 	 	 	 	 	 	N
O	 	P	 	Q	 	R	 	D	 	R
S	 	 	 	 	 	 	 	 	 	E
T	 	 	 	P	 	D	 	 	 	T
E	 	 	 	 	 	 	 	 	 	A
R	E	T	S	O	N	R	E	T	A	P


Why? Based on this

Here is another

I used this to reverse the words
https://textmechanic.com/text-tools/obfuscation-tools/reverse-text-generator/

Since I didn’t know where to go from there I used the following to assign numbers to the letters
http://rumkin.com/tools/cipher/numbers.php

16	1	20	5	18	14	15	19	20	5	18
1										5
20				4		16				20
5										19
18		4		18		17		16		15
14										14
15		16		17		18		4		18
19										5
20				16		4				20
5										1
18	5	20	19	15	14	18	5	20	1	16


I was stuck again, so based on this https://www.youtube.com/watch?v=DRzIeJzjnh0 I did the following. These are the numbers squared
256	1	400	25	324	196	225	361	400	25	324
1										25
400				16		256				400
25										361
324		16		324		289		256		225
196										196
225		256		289		324		16		324
361										25
400				256		16				400
25										1
324	25	400	361	225	196	324	25	400	1	256

These are the mod 9 of those numbers. It was done on excel but you can also use
https://www.miniwebtool.com/modulo-calculator/?number1=10&number2=9

4	1	4	7	0	7	0	1	4	7	0
1										7
4				7		4				4
7										1
0		7		0		1		4		0
7										7
0		4		1		0		7		0
1										7
4				4		7				4
7										1
0	7	4	1	0	7	0	7	4	1	4


Other interesting titbits
In Latin revivescere means “to live again”. A 11 letter word that may fit somewhere
https://www.quora.com/How-can-you-say-the-word-rebirth-in-Latin

You can use this to convert a number to a different base

RD also showed these and asked to think of what snakes symbolized.

as per the wiki they symbolize rebirth and fertility.
