This is a reverse glass painting from southern India. According to a description of the painting published on page 58 of the book ‘Reverse Glass Painting in India’ by Professor Anna L. Dallapiccola:
“Krishna stands with one foot firmly placed on Kaliya's hoods while the other is planted on the serpent’s back. He holds the creature’s tail firmly in his right and holds a flute in his left. The artist delights in the rendering of the youthful and sensuous figure of the bejewelled god, who is splendidly clad in a lower garment with a hip-hugging sash of a vivid red, a light angavastra draped over his arms, and a garland of flowers around his neck.
The pool in the Yamuna, where this incident takes place, is rendered as a circular lotus-filled reservoir teeming with aquatic life. A nagini emerges from the water, elegantly attired and bejewelled, and entreats Krishna to spare her husband's life.”
