Brahmi

The earliest known Indian script is Brahmi

Brāhmī is the modern name given to the oldest members of the Brahmic family of alphabets. The best known inscriptions in Brāhmī are the rock-cut edicts of Ashokain north-central India, dated to the 3rd century BCE. These are traditionally considered the earliest known examples of Brāhmī writing, though recent discoveries suggest that it may be somewhat older, dating back as far as the 6th century BCE (see Tamil-Brahmi).
