This image most probably is of Kali though also has some similarities with the goddess Durga. It has been cast in a very three-dimensional, dynamic way.
Kali is the fierce form of Uma (Parvati). Figures of Kali from northern India tend to show a more fearsome, skeletal form. South Indian depictions are less fierce and more fleshy.
The bronze has developed a particular dark patina. There is also plenty of puja wear.
