A square steatite unicorn seal with a unique inscription was found in the street debris on the inside of the city wall. The two sets of signs on the right hand side of the seal would appear in reverse, i.e.
HARP (Harappa Archaeological Research Project) a group of scholars from a variety of fields dedicated to advancing the study of the ancient Indus Valley civilization.
A steatite unicorn seal from Harappa with Indus script. This seal was found in the central area of Mound E and dates to Period 3B or early 3C, around 2450-2200 BCE. When pressed into clay the impression will be reversed.
Structures in this part of Harappa were sometimes made of a combination of mud-bricks and baked bricks, sometimes mixed in the same wall as seen here in the case of both the southern part of the western wall and part of the northernmost wall.
In the rubble were found a number of inscribed pieces, including this intaglio seal, seen here in situ next to one of the radiating mud-brick walls.
Towards the east, in what was probably a low area, a series of radiating mud-brick retaining walls were built to contain rubble that was used as a foundation for later structures, only fragments of which are preserved.
Excavations during the 1997-2001 seasons were carried out inside perimeter wall . Here a partial plan of those excavations shows superimposed levels of Period 3C buildings, all mostly robbed of their baked brick walls.
