The inscription is in a form of Sanskrit script called Northern Brahmi script, which dates the inscription as being from the second century BCE in either the late Maurya or early Sunga periods. An almost identical inscription also was uncovered nearby and is called the Hathi-vada Inscription. According to K. P. Jayaswal of the Archaeological Survey of India, these inscriptions demonstrate that not only the Kshatriyas but also the Brahmanas or priestly and intellectual class worshiped Krishna as the “Lord of all,” and, thus, Vaishnavism was entrenched in the entire Indian society.
The same point is made in the famous Nanaghat Cave Inscription in the state of Maharashtra, where Vasudeva and Sankarshana (or Krishna and Balarama) are included in an invocation of a Brahmana. On epigraphical grounds, this inscription is dated conclusively as coming from the second half of the first century BCE. Additionally, Raychaudhuri reports:
The Nanaghat Inscription shows further that the Bhagavata [Vaishnava] religion was no longer confined to Northern India, but had spread to the south and had captured the hearts of the sturdy people of Maharashtra. From Maharashtra it was destined to spread to the Tamil country and then flow back with renewed vigor to the remotest corners of the Hindu Vedic world.
There is also much numismatic evidence that corroborates the antiquity of Krishna. For instance, excavations at Al-Khanum, along the border of Afghanistan and the Soviet Union, conducted by P. Bernard and a French archeological expedition, unearthed six rectangular bronze coins issued by the Indo-Greek ruler Agathocles (180?-?165 BCE). The coins had script written in both Greek and Brahmi and, most interestingly, show an image of Vishnu, or Vasudeva, carrying a Chakra and a pear-shaped vase, or conchshell, which are two of the four main sacred symbols of God in Vaishnavism.
