This is Vishwaksena, a Vaishnavite figure. He is Vishnu’s army chief, keeper of Vishnu’s treasury, an obstacle remover and the guardian of gates to Vishnu’s abode, Vaikuntha. As a remover of obstacles, Vishwaksena is to Vaishnavites what Ganesha is to Saivites. But that seems to have changed over a period of time, as Ganesha is invoked and worshipped by Vaishnavites in the capacity of obstacle remover. See Dhatr-Surya(?) image on this site.

Here, Visvakesana is holding the Chakra and Shankha (Discuss and Conch shell) in his rear hands, and the left front hand is supporting the Gada (Mace). Based on these attributes, one could be led to think the bronze is a seated form of Vishnu. One of the noticeable differences is the tarjani mudra of his front right hand. The raised index finger, a threatening gesture, goes with his role as guardian of gates and army chief. Other indications are the absence of a sacred thread across his chest (see the back view) and the absence of the Srivatsa mark on the right side of his chest.

In Vaishnavite temples, Vishwaksena normally has a separate shrine, outside the main deity’s enclosure, and sits facing South. As in here, he normally sits in Lalitasana, with his right leg hanging down and left leg folded and bent towards the right leg.

In some literature, Vishnu is referred to as Vishwaksena, adding to the confusion. R Champakalakshmi, in her book Vaishnava Iconography in the Tamil Country, mentions a version of Vishwaksena with a ploughshare instead of the tarjani mudra. So far, I have not come across that version.

Note the little projection in front on the peetha to support the mace.

This bronze is 1.5 cm, which seems to be the most popular height for the Vishwaksena bronze. There is considerable ritual wear to the top portion. Compare front and back views of Chakra and Sankha. This bronze may date to the eighteenth century.

This bronze is most likely from Karnataka. Visvakesana images are mostly from South India.
