Sometimes, when the legs of Vishnu and Shiva are seen, the icon is called Tripada-Trimurti (three-legged trinity) as opposed to the icon when the legs of Vishnu and Shiva are not shown, when it is called Ekapada-Trimurti (one-legged trinity), although the Uttara-Karanagama refers to the former as Ekapada-Trimurti. When the icon is shown without the torsos of Vishnu and Brahma, it is simply called Ekapada-murti (one-legged icon). Another variation of Ekapada, called Mahesha-Ekapada, appears in an 8th-century relief in Mahabalipuram, where he is one-legged and four-armed but also has three visible heads plus a head assumed at the back and top, making it a five-headed icon, resembling the five-headed form called Mahesha or Sadashiva.
