This is Ambika from the Jain faith, as identified by the branch of mango tree (Amra Lumbi) in her lower right hand and a child on her left lap. The presence of a worn image of a Tirthankara on the Prabhavali reinforces the identification.
There are two other Ambika Vigrahas on this website. See Ambika seated (Gujarat) and Ambika (Western India). This Vigraha merits attention and a place in my collection for several reasons.
To start with it is not common to see Jain Vigraha done in folk style.
The style is typical of Kandesh region, in Maharashtra. More like Central India, if one were to ignore administrative boundaries.
Kandesh bronzes are characterized by plain Prabhavali with beaded edges, the pedestal featuring multiple small figures, the prabhavali topped by a well-detailed Kalasa and folk style casting. Thanks to Ameet for this information.
Another interesting aspect of this Vigraha is the four-armed depiction, with her upper arms holding something circular. They are Lotus flowers. The book Jaina Rupa Mandana by Umakant P Shah has an example from Central India (Fig 91), of a four-armed Ambika holding lotus flowers in her upper arms.
The presence of nine balls/beads on the front rim of the base is an unusual addition, especially for an ancillary deity. Normally you see this feature, representing Navagraha (nine planets), in Tirthankara bronzes.
The image of feet (on the left) and the rectangular feature (on the right) are yet to be explained.
The inscription on the back is worn and it is difficult to decipher. This Vigraha is 400+ years old. It is 9 cm tall.
