A Tamil-Brahmi script inscribed on a potsherd, which was found at the Khor Rori area in Oman, has come to light now. The script reads “nantai kiran” and it can be dated to first century CE, that is, 1900 years before the present. The discovery in the ancient city of Sumhuram has opened a new chapter in understanding the maritime trade of the Indian Ocean countries, according to specialists in history.
