The concept of a four-headed Vishnu first appears in the Hindu epic Mahabharata, but the complete iconography was first found in a 5th-century Pancharatra text. The icon reflects influences from the Gupta period and the Gandhara architectural tradition. While as per one interpretation, the animal heads represent Vishnu's avatar Narasimha (lion-headed man) and Varaha (boar), another theory based on Pancharatra texts relates the four heads to the Chaturvyuha: Vāsudeva (Krishna), Saṃkarṣaṇa (Balarama), Pradyumna and Aniruddha - four vyuhas (manifestations) of Vishnu. A cult centered on Vaikuntha Chaturmurti developed in Kashmir in the 8-12th century, when the deity also enjoyed royal patronage in the region. The Lakshmana Temple of Khajuraho suggests his worship in the Chandela kingdom (Central India) in the 10th century.
