The most widely known of these images was named the “Pashupati seal”by its discoverer, John Marshall, who believed that it represented a “proto-Shiva” figure. Many modern authorities discount the idea that this “Pashupati” (Lord of Animals, Sanskrit pasupati) represents a Shiva or Rudra figure. Gavin Flood also characterizes these views as “speculative”, saying that it is not clear from the ‘Pashupati’ seal that the figure is seated in a yoga posture, or that the shape is intended to represent a human figure. Authorities who support the idea that the ‘Pashupati’ figure shows a figure in a yoga or meditation posture include Archaeologist Jonathan Mark Kenoyer, current Co-director of the Harappa Archaeological Research Project in Pakistan and Indologist Heinrich Zimmer.
