Note that "mudras" have significant meanings in Hinduism, Jainism & Buddhism. Mudras used in Indian dances convey feelings or elements of story etc. Also used in yoga. And mudras are not just hand gestures but also facial expressions, eye movements and so on.

Though there does not seem to be any connection of mudras with European paintings. There were cultural links between India and the Greco-Roman world in 2nd-1st century BCE around the time of Indo-Greek kingdom (northwest of the current India) but seems unlikely that would have such an influence centuries later.
