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.
Harappa, Punjab ancient Indus civilization excavations, figurines, seals and other objects.
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.
The majestic zebu bull, with its heavy dewlap and wide curving horns is perhaps the most impressive motif found on the Indus seals.
Mound AB, whose origins actually go back five and a half thousands years to 3500 BCE, seen from the rich crop fields that surround many ancient Indus cities including Mohenjo-daro and Dholavira.
An enormous amount of work to do, and only a tiny proportion most ancient Indus sites like Harappa, Mohenjo-daro and Dholavira have been excavated.
A small fraction of Harappa has actually been excavated. Most of the site is untouched by the archaeologists tools. It may be that future non-invasive techniques like ground penetrating radar help us map out what remains under the soil.
