From the Museum Site: Brimming with a fearsome energy that radiates from his coiled hair, menacing smile, and angry gaze, Bhairava is a terrifying form of the Hindu god Shiva. His bulging eyes and sharp fangs signal his wrath, and the skull adorning his hair points to his association with cremation grounds. The mismatched earrings allude to his complex character: As a powerful god, Shiva embodies contrasting qualities, both peaceful and violent, both creative and destructive.
