Can someone answer me a Q about iconography

[donna123]

We have been on holiday to Greece and have seen lots of icons in churches. DD wants to know why Christ is often shown in a certain pose; what is its meaning or symbolism.
It's the pose where he holds up his right hand with the first and second fingers skyward and the ring-finger touching the thumb. Like this. Why? Why not thumb and first finger. Or thumb and pinkie, or any other combination. Why thumb and ring finger?

I'm fascinated by iconography, but only know a little about it. I found this explanation:

donna123 I think you'll find it represents the first and last letters in the Greek for Jesus Christ IC XC (IESOUS XRISTOS). In Greek lower case sigma at the end of a word looks rather a "C" with a tail!
