This is Khandobha and his consort Mahalsa riding a horse. This is one of the popular depictions of them. Khandobha is identified by his vahana, a horse, and by his attributes, a sword, the Trishul, drum and a shield. Clockwise starting the lower right hand. They are accompanied by a dog.
Khandobha widely worshipped in the Deccan region and the primary temple for Khandobha is located in the town Jejuri.
The backdrop is full-length prabhavali with Kiritimuka, the face of glory, and five-hooded cobra. The absence of Makara in the prabhavali suggests this bronze may be from the Northern part of West Deccan, South Maharashtra.
A complete set of Khandobha, like this one, horse, dog, deities and prabhavali, is rarer. This is a four-piece construction and pieces get separated. And that is one of the reasons for the rarity of a complete set. See the photo on the side.
Like in most of the folk bronze, the posture of the horse and the deities are rigid.
This bronze is about 27 cm in height and it is most likely from South Maharashtra. This may date to the nineteenth century or a bit earlier.
