|124. Inscribed Ravi sherd|
The origins of Indus writing can now be traced to the Ravi Phase (c. 3300-2800 BC) at Harappa. Some inscriptions were made on the bottom of the pottery before firing. Other inscriptions such as this one were made after firing. This inscription (c. 3300 BC) appears to be three plant symbols arranged to appear almost anthropomorphic. The trident looking projections on these symbols seem to set the foundation for later symbols such as those seen in 131.
