This paper reviews the assemblage of inscribed and incised objects discovered at the site of Harappa during excavations conducted between 1986–2007 by the Harappa Archaeological Research Project (HARP). Ever since the discovery of the first engraved seals of the Indus Civilization at the site of Harappa, scholars have been trying to unlock the secrets of the Indus script1 and to understand the social, economic, and political importance of these and other inscribed objects. Although the inscriptions have remained undeciphered, it has been possible to gain some insight into the context for the use of the script based on carefully documented recovery of inscribed objects from recent excavations throughout the greater Indus region.
