South India is known for its distinctive metalwork. It is also known for its elaborate ceremonial rituals where lamps play an important role. Some are multi-tiered floor stands, or hanging lamps in various sizes, oil lamps, and changalavatta (commonly known as the Greek lamps). This deep, brass lamp is simple but strong in form. It is specially made for rituals where the flame is to be kept alight for hours together or till the ceremony is over. It is deep and wide enough to hold a large quantity of oil and a long wick. It is shaped like a traditional oil lamp, simple but for the handle by which the priests or a devotee holds the lit lamp.
