Iravatham Mahadevan, another historian who supports the Dravidian hypothesis, says, "we may hopefully find that the proto-Dravidian roots of the Harappan language and South Indian Dravidian languages are similar. This is a hypothesis [...] But I have no illusions that I will decipher the Indus script, nor do I have any regret".[46] According to Mahadevan, a stone celt discovered in Mayiladuthurai (Tamil Nadu) has the same markings as that of the symbols of the Indus script.
