The earliest deciphered epigraphy found in the Indian subcontinent are the Edicts of Ashoka of the 3rd century BCE, in the Brahmi script.
[4] Indian epigraphy becomes more widespread over the 1st millennium, engraved on the faces of cliffs, on pillars, on tablets of stone, drawn in caves and on rocks, some gouged into the bedrock.
[9] Until the 1990s, it was generally accepted that the Brahmi script used by Ashoka spread to South India during the second half of the 3rd century BCE, assuming a local form now known as Tamil-Brahmi.
Beginning in the late 1990s, archaeological excavations have produced a small number of candidates for Brahmi epigraphy predating Ashoka.
The inscription is carved on a pillar, that was discovered in the village of Halmidi, a few miles from the famous temple town of Belur in the Hassan district of Karnataka, and is dated 450 CE.
Tamil copper-plate inscriptions are mostly records of grants of villages or plots of cultivable lands to private individuals or public institutions by the members of the various South Indian royal dynasties.
These plates are valuable epigraphically as they give us an insight into the social conditions of medieval South India and help fill chronological gaps to connect the history of the ruling dynasties.
Literary works in India were preserved either in palm leaf manuscripts (implying repeated copying and recopying) or through oral transmission, making direct dating impossible.
[23][24][25] Epigraphic attestation of Tamil begins with rock inscriptions from the 3rd century BCE, written in Tamil-Brahmi, an adapted form of the Brahmi script.
The plate is a record documenting a donation in the reign of king Budhagupta (circa CE 477–88) in year 168 of the Gupta era.
