a divine buffalo-man. The interpretation of the seal continues to be disputed. McEvilley, for example, states that it is not possible to "account for this posture outside the yogic account". Asko Parpola states that other archaeological finds such as the early Elamite seals dated to 3000–2750 BCE show similar figures and these have been interpreted as "seated bull" and not a yogi, and the bovine interpretation is likely more accurate. Gregory L. Possehl in 2002, associated it with the water buffalo, and concluded that while it would be appropriate to recognize the figure as a deity, and its posture as one of ritual discipline, regarding it as a proto-Shiva would "go too far". Vedic elements According to Anthony, the Old Indic religion probably emerged among Indo-European immigrants in the contact zone between the Zeravshan River (present-day Uzbekistan) and (present-day) Iran. It was "a syncretic mixture of old Central Asian and new Indo-European elements", which according to Beckwith borrowed "distinctive religious beliefs and practices" from the Bactria–Margiana Culture. At least 383 non-Indo-European words were borrowed from this culture, including the god Indra and the ritual drink Soma. Proto-Indo-European elements The Vedic beliefs and practices of the pre-classical era were closely related to the hypothesised Proto-Indo-European religion, and the pre-Islamic Indo-Iranian religion. The similarities between the iconography and theologies of Shiva with Greek and European deities have led to proposals for an Indo-European link for Shiva, or lateral exchanges with ancient central Asian cultures. His contrasting aspects such as being terrifying or blissful depending on the situation, are similar to those of the Greek god Dionysus, as are their iconic associations with bull, snakes, anger, bravery, dancing and carefree life. The ancient Greek texts of the time of Alexander III of Macedonia call Shiva as "Indian Dionysus", or alternatively call Dionysus as "god of the Orient". Similarly, the use of phallic symbol as an icon for Shiva is also found for Irish, Nordic, Greek (Dionysus) and Roman deities, as was the idea of this aniconic column linking heaven and earth among early Indo-Aryans, states Roger Woodward. Others contest such proposals, and suggest Shiva to have emerged from indigenous pre-Aryan tribal origins. Rudra Shiva as we know him today shares many features with the Vedic god Rudra, and both Shiva and Rudra are viewed as the same personality in Hindu scriptures. The two names are used synonymously.
