This is a reverse glass painting from southern India. According to a description of the painting published on page 75 of the book βReverse Glass Painting in Indiaβ by Professor Anna L. Dallapiccola:
βA hall supported by pillars with a draped curtain hanging from its ceiling, provides the backdrop to the ritual depicted in the foreground. The absence of obvious clues makes it difficult to interpret the scene. It is probable, however, that the painting illustrates an episode drawn from the Mahabharata. Yudhishthira (on the right) flanked by Draupadi sits at the side of the fire pit and pours oblations into the flame. Bhima, recognisable by his imposing size, dark complexion and his club, stands behind the couple. In the foreground, to the left of Draupadi is a crowned seated figure, probably one of the twins, either Nakula or Sahadeva. Opposite Yudhishthira, facing the sacrificial flame, sits a sage, holding a container in his left hand and raising his right hand as if reciting prayers. Near him is a second, smaller ascetic in the same pose. Behind them stand two further personages: the green-complexioned Arjuna, recognisable by the bow and quiver slung on his shoulder and possibly, the second twin. Various ritual implements and offerings dot the foreground.β
