Tarjani Mudra and Cornuta

An interesting similarity in form and meaning: The Tarjani Mudra and the Corna gesture (Horns or Cornuta). They are used in both cultures or gesture systems as a symbol to ward of evil.

The Tarjani Mudra is to be made only with the index finger. And here is a source mentioning that the Tarjani-mudra is the same as the Abhaya-mudra.
