Pashupati seal

An early description and analysis of the seal's iconography was provided by archaeologist John Marshall who had served as the Director-General of the Archaeological Survey of India and led the excavations of the Indus Valley sites. In addition to the general features of the seal described above, he also saw the central figure as a male deity; as three-faced, with a possible 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.[9] In a 1928–29 publication, Marshall summarized his reasons for the identification as follows:

My reasons for the identification are four. In the first place the figure has three faces and that Siva was portrayed with three as well as with more usual five faces, there are abundant examples to prove. Secondly, the head is crowned with the horns of a bull and the trisula are characteristic emblems of Siva. Thirdly, the figure is in a typical yoga attitude, and Siva [sic] was and still is, regarded as a mahayogi—the prince of Yogis. Fourthly, he is surrounded by animals, and Siva is par excellence the "Lord of Animals" (Pasupati)—of the wild animals of the jungle, according to the Vedic meaning of the word pashu, no less than that of domesticated cattle.[5]

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.[9][10] 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. For instance, Herbert Sullivan, wrote in 1964 that Marshall's analysis "has been accepted almost universally and has greatly influenced scholarly understanding of the historical development of Hinduism".[11] 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-Śiva character of the seal has been accepted."[12] Thomas McEvilley noted, in line with Marshall, that the central figure was in the yoga pose Mulabandhasana, quoting the Kalpa Sutra's description "a squatting position with joined heels" used with meditation and fasting to attain infinite knowledge (kevala).[13] And 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".[14] A lot of discussion has taken place about this seal.[15] While Marshall's work has earned some support, many critics and even supporters have raised several objections.[16]

Doris Srinivasan, a professor of Indian studies, raised objections to Marshall's identification, and provided a new interpretation for the figure, where she postulated the lateral projections were cow-like ears rather than faces. In 1975-76, she published a journal article titled 'The So-Called Proto-śiva Seal from Mohenjo-Daro: An Iconological Assessment' in the academic journal Archives of Asian Art.[17] In 1997, she reiterated her views in a book titled Many Heads, Arms, and Eyes: Origin, Meaning, and Form of Multiplicity in Indian Art.

Mahishasura, the buffalo demon being slayed by the goddess Durga

According to her, the two extra faces could be reinterpreted as possible ears, and the central face has predominant bovine features. She has drawn similarities between the central figure of seal 420, and other artefacts from the Indus Valley such as the horned mask from Mohenjo-Daro, the terracotta bull from Kalibangan, and the depiction of a horned deity on a water pitcher from the archaeological site of Kot Diji. She has also noted that the yogic posture of the figure is repeated on a number of other seals and sealings, some of which indicate that the figure receives worship. On the basis of these observations, she suggests that the figure of seal 420 could be a divine buffalo-man.[18]

Scholars who consider the Indus Valley Civilisation to be associated with Dravidian culture have offered other interpretations. According to Alf Hiltebeitel, Professor of Religion, History, and Human Sciences at George Washington University[19], the horned figure could be identified with Mahishasura, the buffalo demon enemy of the Hindu goddess Durga. He has also argued that the tiger depicted in the seal could represent the goddess Durga who is often depicted as ridding a tiger (or a lion) in the Hindu pantheon. He also suggested that the surrounding animals could represent the vahanas (vehicles, mounts) of deities for the four cardinal directions.[20][21]

Herbert Sullivan from Duke University[22] interpreted the figure as a female goddess on the grounds that the so-called erect phallus actually represents a girdle, a feature he had found only on female figurines.[11] The American archaeologist Walter Fairservis tried to translate what he considered to be a Dravidian inscription, and was of the view that the seal could be identified with Anil, the paramount chief of four clans represented by the animals. The Finnish Indologist, Asko Parpola has suggested that the yogic pose could be an imitation of the Proto-Elamite way of representing seated bulls. He attempted to translate the inscription which he considers to be an early form of Dravidian, and found that the figure represents a servant of an aquatic deity.[23] He finds that the animals depicted on the seal best resemble those associated with the Hindu god Varuna who could be associated with the aquatic themes which are prominent in the Indus religion. [21]

Agni is the god of fire, and a prominent deity in the Vedas.

There are some scholars who think the seal represents a Vedic deity, and believe that this points to an Indo-Aryan identity of the Indus Valley Civilisation. The Indian archaeologist, S.R. Rao who is credited with discoveries of a number of Harappan sites, identified the figure in the seal with the Vedic deity Agni. He attempted to translate the text and claimed that the evidence pointed to the three-headed blazing, fire god Agni who belongs to the Vedic pantheon. The animals represent the various clans which accepted the supremacy of Agni.

E. Richter-Ushanas identified the figure with the sage Rishyasringa who was born with horns, and who officiated the sacrifice of King Dasaratha in the ancient Indian epic Ramayana. The considers the four animals to be a representation of the four seasons, and found similar motifs on the Gundestrup cauldron discovered in Denmark. Other scholars such as Talageri, Rajaram and Frawley, have postulated that the cauldron presents compelling evidence towards India as the home of the Indo-European people. S.P. Singh identified the figure with the Hindu god Rudra who is associated with the storm and the hunt. He identified the surrounding animals with the Maruts who are storm deities and sons of Rudra. His argument for this identification is based on hymn 64 of the first mandala (book) of the Rigveda which compares the Maruts to various animals, including a bull, an elephant, a lion, a deer, and a serpent.[24] M.V.N. Krishna Rao identified the figure with the Hindu god Indra. He argued that the tiger could be ignored since it's much larger than the other animals, and the two deer could also be ignored since they were seated under the table. Then he combined the first phoneme of each of the animals, and the word 'nara' meaning man, and arrived at the term 'makhanasana' which is an epithet of Indra.[21]
