Seals
Archaeologists have discovered thousands of seals, mostly made of steatite, and occasionally of agate, chert, copper, faience and terracotta, with beautiful figures of animals, such as unicorn bull, rhinoceros, tiger, elephant, bison, goat, buffalo, etc. The realistic rendering of these animals in various moods is remarkable. The purpose of producing seals was mainly commercial. It appears that the seals were also used as amulets, carried on the persons of their owners, perhaps as modern-day identity cards. The standard Harappan seal was a square plaque 2×2 square inches, made from steatite.
Every seal is engraved in a pictographic script which is yet to be deciphered. Some seals have also been found in ivory. They all bear a great variety of motifs, most often of animals including those of the bull, with or without the hump, the elephant, tiger, goat and also monsters. Sometimes trees or human figures were also depicted. The most remarkable seal is the one depicted with a figure in the centre and animals around. This seal is generally identified as the Pashupati Seal by some scholars whereas some identify it as the female deity.
This seal depicts a human figure seated cross-legged. An elephant and a tiger are depicted to the right side of the seated figure, while on the left a rhinoceros and a buffalo are seen.
