Garuda is Vishnu’s vahana (vehicle). Normally a standing figure, with hands folded at the chest level, in worshiping Anjali (offering oneself to the God) mudra.
Beak shaped nose and stretched wings attached to the back of his hands with human body are his distinguishing features.
This Ganga Jamuna, bimetallic, icon are rare. This would have been a part of a set consisting of Vishnu, Sridevi and Bhudevi. This is probably from North Karnataka and may not be older than 18th century.
Garuda is usually installed opposite to the main shrine of god in the Vishnu temple, not different to the way Nandi shrine relate to Siva in a temple.
This Garuda is well sculpted piece and the details are just fantastic. It is about 13.5 cm tall and is quite heavy. The complete set would have been even more impressive.
