Origin of the Shield Shape in the Solar Folio of the f85-86 Foldout

[Dobri]

While trying to find a proper name for the 'O'-shaped shield frame in the solar folio of the f85-86 foldout,
I came across the following description concerning You are not allowed to view links. Register or Login to view.: 

"Clergy have used less-military shapes such as the oval cartouche, but the shield has always been a clerical option. Clergy in Italy often use a shield shaped like a horse's face-armor."

Among the You are not allowed to view links. Register or Login to view., there is a nice Benedictine coat of arms from Mosteiro de Tibães in Braga, Portugal.

Notice the depiction of the Sun in the upper quadrant on the left-hand side of said coat of arms.

Here is an oddity worth mentioning, see the attached image of Lithuanian Coat of arms of the Sun symbolizing Podolia (1416). 

[Dobri]

The sun in the solar folio of the f85-86 foldout has 14 rays while the Lithuanian coat of arms has 13 rays. 

The description of the You are not allowed to view links. Register or Login to view. is as follows: "Radiant sun - a Lithuanian Coat of Arms in the Council of Constance in 1416. From an Armorial (a book of coats-of-arms), produced in 1416. Made by a Portuguese herald, attending the Council of Constance".

The horse's-face-armor shape survives in modern times and is shown here on the ceiling of the Benedictine You are not allowed to view links.

The symbol combination odar occurs 115 times, first in f1r.6, and then 21 times as a distinct vord and 93 times with numerous prefixes and suffixes (highlighted in yellow). The number of occurrences for every distinct vord is enclosed in parentheses.

   

There are 15 distinct symbols preceding odar (highlighted in green) and their number of occurrences is shown below.
One of said symbols could possibly be 'V' or 'U' starting from the most frequently observed e, ch, q, k, etc.

   

Note that y never precedes odar.
Actually, y precedes o in other vords only 29 times in the entire manuscript. Also, o precedes y only 109 times.
The symbols o and y are rarely observed next to each other.

Many of the glyphs have trends that are hard to account for, such as, why does it never start a word? why does it never end a word?
It's obviously more complex than that, but some simple examples. Once you try to assign something you will run into these. 

There is a cool example of something looking maddeningly like plain-text that I got a tiny bit obsessed with once upon a time. On You are not allowed to view links. Register or Login to view. there is (in the top right) a man with liquid(?) going into his mouth.. or out, anyway, I think it might be the only example of this clearly happening in the manuscript. Next to him is the text "s oral"

I guess the point is, however strong the link seems, it will fall apart once applied elsewhere and we only have so much time, so it might not be the best use of your time. 
Obviously its up to you though. 

I noticed you mentioned the use of EVA: "y" and "o", and I don't think I can comment without infecting your thread with my theories.. so I would just say if you are interested in this stuff I would suggest checking out Stolfi's work

One could even question the depiction of the Sun  (although it is on a blue background) as it could also be a depiction of the Moon, follow the link to see an image of You are not allowed to view links. Register or Login to view. (obviously made after the invention of the printing press).

The clockwise outward blue whirlwind in the 'Solar' folio seems to depict the passage of time throughout four stages in a medieval Wheel of Fortune.

... There are 15 distinct symbols preceding odar (highlighted in green) and their number of occurrences is shown below... 

Note the divisibility by 5 of the number of distinct symbols preceding odar.

The first observation of divisibility by 5 or 10 (concerning distinct vords) was reported in You are not allowed to view links. Register or Login to view. of the thread "You are not allowed to view links. Register or Login to view.".
