fourth face towards the back; and, as ithyphallic, while conceding that what appeared to be the exposed phallus could instead be a tassel hanging from the waistband. Most significantly he identified the seal as an early prototype of the Hindu god Shiva (or, his Vedic predecessor, Rudra), who also was known by the title Pashupati ('lord or father of all the animals') in historic times. In a 1928–29 publication, Marshall summarized his reasons for the identification as follows: Later, in 1931, he expanded his reasons to include the fact that Shiva is associated with the phallus in the form of linga, and that in medieval art he is shown with deer or ibexes, as are seen below the throne on the seal. Marshall's analysis of the Indus Valley religion, and the Pashupati seal in particular, was very influential and widely accepted for at least the next two generations. Herbert Sullivan, who had significant disagreements with it, recognised in 1964 that Marshall's analysis "has been accepted almost universally and has greatly influenced scholarly understanding of the historical development of Hinduism". Writing in 1976, Doris Srinivasan introduced an article otherwise critical of Marshall's interpretation by observing that "no matter what position is taken regarding the seal's iconography, it is always prefaced by Marshall's interpretation. On balance the proto- character of the seal has been accepted." Thomas McEvilley noted, in line with Marshall, that the central figure was in the yoga pose Mulabandhasana, quoting the Kalpa Sutras description "a squatting position with joined heels" used with meditation and fasting to attain infinite knowledge (kevala). Alf Hiltebeitel noted in 2011 that, following Marshall's analysis, "nearly all efforts at interpreting the [Indus Valley] religion have centered discussion around [the Pashupati seal] figure". A lot of discussion has taken place about this seal. While Marshall's work has earned some support, many critics and even supporters have raised several objections. Herbert Sullivan interpreted the figure as a female goddess on the grounds that the so-called erect phallus actually represents the dangling end of a waistband or girdle, a feature found on many undoubtedly female terracotta figurines, and ambiguous on some other seals, including DK 12050 (mentioned above). Marshall himself had admitted this was possible. In the terracottas, males are always nude; in addition, the jewellery worn on the Pashupati seal is characteristic of female rather than male terracottas.
