This is Kannadi Bimbam. It roughly translates to Mirror Deity. Smaller versions of this are worshipped at homes in Kerala. They are believed to reflect positive thoughts and also help in introspection.

While they are worshipped on their own, some view them as a representation of the Mother Goddess Bhagwati. The iconographic variations of Kannadi Bimbam as Mother Goddess are shown below.

The second and third photos are from the Internet, with Thanks.

It appears the iconography in Kerala is not bound by strict traditions, and the fragmented society allows the devotees to adapt and innovate.

This Kannadi Bimbam with me is modern, and it is a work of art. I first saw Kannadi Bimbam in an article in The Hindu, a newspaper, about fifteen years ago. The idea appealed to me. Since then, I have been looking for one. A dealer from Kerala arranged this for me. It is a new 21st-century item, and it is the most recent bronze in my collection. That does not stop me from giving it the central position on my work desk. See the photo below.

This Kannadi Bimbanm is about 42 cm tall.

Note: The Kannadi Bimbam is distinct from the Aramulla Mirror, which is normally a part of the bride’s wedding trousseau
