The Vishnudharmottara Purana prescribes that Vishvarupa have four arms and should have as many as arms that can be possibly depicted. A 12th-century sculpture of Vishvarupa from Rajasthan shows a fourteen-armed Vishnu riding his mount Garuda. The image has three visible human heads, unlike the early sculptures which include animal ones. Some iconographic treatises prescribe a fourth demonic head at the back, however this is generally not depicted in iconography.
