Archaeologists have unearthed a potsherd with Tamil letter ‘Tha’ inscribed on it from Keeladi, Sivagangai District.
It is a Sangam-era urban settlement site on the banks of River Vaigai in Madurai.
This is the first recovery of Tamili (Tamil-Brahmi) inscribed potsherd in the 10th season of digging
Keeladi is 12 km southeast of Madurai where excavations first began in 2014.
This site has borne enough evidence of an urban industrialised settlement, with carbon-dating of artefacts from the site establishing its age to be 2,600 years old.
