This unusual Surya is from South India. Surya is identified by the two lotus buds in his hands. Surya from North India / Esat India tend to hold lotus flowers as opposed to buds that we see in this case. This site has several examples of Surya (And I have not stopped collecting them). For more information on Surya see the example from the Pala period and/or the one from Kashmir region.
The unusual aspect is the five-hooded cobra under which he is standing. Deities standing under Cobra hood are common among Vaishnavite Vigrahas. Below are two examples of Krishna standing under Cobra hood.
When it comes to Surya this is the first such example for me. Innovation in iconography does not seem to stop.
One of my collector friends suggested this may be a representation of Naga, the snake God. A search of Nagakal, did not give any positive results. Where a human-like figure is shown in Nagakal, they are shown in Anjali Mudra.
Swanand gave me an example of a stone sculpture with similar iconography. The sculpture is somewhere near Sangli and it is shown on our right. Thanks to Swanand, the geographical attribution is strengthened.
The vigraha is about 8.5 cm in height and it may be about 150-200 years old. It does not show much wear, but the patina is strong. It is from Karnataka.
