I posted this one because of the photograph in the left end of the screen. The picture is of "the number" of the beast in the Vatican codex. A date of some kind is on it, so I'm not sure if that is in the actual hand of the disciple John or not. (but it's old).
I'm excited to post on this because I've had a math "history" class which included learning (among other ancient numbers) Ionic and Attic Greek numbers.
There are some glaring things in the picture and in the interpretations that simply DON'T ALIGN.
First - the correct way to express 666 in Ionic Greek numbers is: Chi, Xi, DIGAMMA (600+60+6=666) - sort of like our (also) base ten numbers.
Ionic numbers fit together as hundreds, tens, ones. in order. Everyone who speaks on THAT number says "Chi, Xi, SIGMA (not sTigma -whole other word)
1. Ionic numbers don't work like that (100's+10's+100's? NO!) Chi,Xi,Sigma=600+60+200=860
2. The "third" character is neither a Digamma OR a Sigma. - it sort of vaguely resembles a sigma - same way a rabbit sort of looks like a water buffalo. (four legs, ears, a nose, etc.)
I saw a video where someone installed the correct character for six (the digamma) and called it a sigma - the one in the codex is most definitely NOT a digamma - even if the author were barfing drunk and had eaten suspicious mushrooms - it isn't a digamma.
I sincerely believe it aint a sigma neither - AND it doesn't make sense as a number IF IT WAS. (860 would be expressed as omega,Xi)
I can't read Arabic and I've heard two different interpretations on it. (the muslim's interpretation was based on the inappropriately installed digamma.)
I prefer hearing Walid Shoebat talk on it, but he didn't provide an actual image of the "number".
Anyway, I'm just glad I could offer that bit on greek numbers.
