Rakshasa Viradha seen with Lord Rama and others

Viradha is a character from the Aranya Kanda of the Ramayana. He is a rakshasa or demon  living in Dandaka forest who briefly kidnaps Sita; Rama and Lakshmana begin to battle the monster, but though they shoot it with many arrows, the arrows pass straight through him and leave him unharmed. A depiction of the rakshasa as one can see that he is unaffeceted by the arrows and his split head.
