Shiva is depicted with five heads and four arms. He is typically clothed in animal skins and garlanded with snakes. In his hands he holds various attributes including his trident and drum. In order to depict four frontal heads the artist has used a common device whereby five eyes are shared between the four faces. The second work depicts the goddess Kaumari.
