Most of the time I can’t tell with Sleepy’s Word Salad.

I am however very excited about 45’s rally. I need a fix. It’s raining here. I’ve done my declutter for the day and cooked supper for hubs.

Now I’m making myself buggy researching why omicron would be inscribed in Jesus’ cruciform halo in centuries old Icons. Now symbols just keep me going since being with Q.

I started with the etymology
Excerpts

omicron (n.)
15th letter of the Greek alphabet, c. 1400, literally “small ‘o,’ “ from o + Greek (s)mikros “small” (see micro-). So called because the vowel was “short” in ancient Greek. Compare omega.

omega (n.)
final letter of the Greek alphabet, c. 1400, from Medieval Greek omega, from classical Greek o mega “big ‘o’ “ (in contrast to o micron “little ‘o’ “); so called because the vowel was long in ancient Greek. From o + megas “great, large, vast, big, high, tall; mighty, important” (from PIE root *meg- “great”). Used figuratively for “the last, the final” of anything (as in Revelation i.8) from 1520s.

O
fifteenth letter of the alphabet, from a character that in Phoenician was called ‘ain (literally “eye”) and represented “a very peculiar and to us unpronounceable guttural” [Century Dictionary]. The Greeks also lacked the sound, so when they adopted the Phoenician letters they arbitrarily changed O’s value to a vowel. (Thus there is no grounds for the belief that the form of the letter represents the shape of the mouth in pronouncing it.) The Greeks later added a special character for “long” O (omega), and the original became “little o” (omicron).
In Middle English and later colloquial use, o or o’ can be an abbreviation of on or of, and is still literary in some words (o’clock, Jack-o’-lantern, tam-o’-shanter, cat-o’-nine-tails, will-o’-the-wisp, etc.).
O’ the common prefix in Irish surnames is from Irish ó, ua (Old Irish au, ui) “descendant.”
The “connective” -o- is the usual connecting vowel in compounds taken or formed from Greek, where it often is the vowel in the stem. “[I]t is affixed, not only to terms of Greek origin, but also to those derived from Latin (Latin compounds of which would have been formed with the L. connecting or reduced thematic vowel, -i), especially when compounds are wanted with a sense that Latin composition, even if possible, would not warrant, but which would be authorized by the principles of Greek composition.” [OED]
As “zero” in Arabic numerals it is attested from c. 1600, from the similarity of shape. Similarly the O blood type (1926) was originally “zero,” denoting the absence of A and B agglutinogens.

I found it very interesting the definition (maybe they were all deaf or couldn’t understand each other-deaf Phoenician and why the used symbols) of O in Phoenician was called ‘ain (literally “eye”)

Great Eye
Big Eye
Little Eye
It’s Not plural
Single Eye?
???

Is it about the verse in Luke?

(Luke 11:22-23)

22The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light. 23But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!

Greek, Hieroglyphics, Phoenician symbolism.
To me symbolism is like tokpisin = talk pigeon (talk over my pigeon head more like.)

The O blood type reference intrigued me as well, especially with the bloodline and blood testing talk over time.

Sigh! Another Rabbit Hole.
