Many saints are often depicted holding a book or some other object. However, I have noticed that there are quite a few that have unusual hand gestures. Why is this?
Index finger, middle finger, and ring finger together, other fingers spread out
Ring finger and pinky against thumb
Index finger against thumb, middle finger extended
I'm going to assume that the modern vulgar meaning for this gesture was not intended.
Index and middle fingers crossed, ring finger against thumb
Ring finger against thumb, back perspective
