This very fine and delicate bronze image is of Bhu Devi (Prithivi), one of the two consorts of Vishnu. It dates to the later Chola period (12th-13th century.)
It is small but particularly finely cast and has all the details of much larger bronzes from the Chola period.
Chola nuances include a long face; a prominent, an almost aquiline nose; a particularly beautiful, fine waist; and a particular placing of the feet with one turned out to the side.
The image stands on a square platform. Bhu Devi is depicted nearly always without a horizontal kuchabandha or breast band, whereas Sri Devi, the other consort Vishnu, usually is shown with such a band.
Bhu Devi holds a lotus flower in the right hand. She has a striped dhoti, with ample waist bands, various jewellery items, and a tall, multi-tiered karandamukuta headdress.
The patina shows much age and surface degradation consistent with great age. The bronze is in fine condition and without loss or repairs.
