A Neolithic stone shaped like a hand held axe, dating to between 2000 BC – 1500 BC has been found near Mayiladuthurai in Tamil Nadu. What makes this find more interesting is the fact that this stone has Indus Valley signs on it. This is one great find since this brings out evidence that the Indus script had reached Tamil Nadu around the same time the Indus civilization was in its glory.
According to Mr. Mahadevan, the first sign on the celt depicted a skeletal body with ribs. The figure is seated on his haunches, body bent and contracted, with lower limbs folded and knees drawn up. The second sign showed a jar. Hundreds of this pair have been found on seals and sealings at Harappa. Mr Mahadevan read the first sign as “muruku” and the second sign as “an.” In other words, it is “Murukan.” The earliest references in Old Tamil poetry portrayed him as a “wrathful killer,” indicating his prowess as a war god and hunter. The third sign looked like a trident and the fourth like a crescent with a loop in the middle.[Discovery of a century" in Tamil Nadu via email from Anand Krishnamoorthi]
Does this mean that Harappans and the people of Tamil Nadu shared a same language? Iravatham Mahadevan, an expert on Indus Valley script thinks so.
He said: “`Muruku’ and ‘an’ are shown hundreds of times in the Indus script found at Harappa. This is the importance of the find at Sembiyan-Kandiyur. Not only do the Neolithic people of Tamil Nadu and the Harappans share the same script but the same language.” In Tamil Nadu, the muruku symbol was first identified from a pottery graffiti at Sanur, near Tindivanam. B.B. Lal, former Director-General of ASI, correctly identified this symbol with sign 47 of the Indus script. In recent years, the muruku symbol turned up among the pottery graffiti found at Mangudi, near Tirunelveli in Tamil Nadu, and at Muciri, Kerala. But this was the first time that a complete, classical Indus script had been found on a polished Neolithic stone celt, Mr. Mahadevan pointed out.[ Significance of Mayiladuthurai find]
