The lost Langauge
Archaeologists think that the culture was a theocracy. But no site of a temple has been found. As with other cultures, the rulers of the Harappan civilization are believed to have close to ties to religion. Priests probably prayed for good harvest and safety from floods. Religious artifacts reveal links to modern hindu culture. Hinduism was based on the cast system.
The Harappan cities show a remarkable uniformity in religion and culture. The housing suggests that social divisions in the society were not great. Artifacts such as clay and wooden children's toys suggest a reletively prosperous society that could afford to produce nonessential goods.
Like the other two river valley civilizations, the Harappan culture developed a written language. In contrast to cuneiform and hieroglyphics, the Harappan language has been impossible to decipher. This is because, unlike the other two languages, linguists have not found any inscriptions that are bilingual. The harappan langauge is found on stamps and seals made of carved stone used for trading pottery and tools.
The harappans conducted a thriving trade with peoples in the religion. Gold and silver came from the north in afghanistan. Semiprecious stones from Persia and the Deccan Plateau were crafted into jewelry. The Indus River provided an excellent means of transportation for trade goods. Brightly colored cotton cloth was a desirable trade item since few people at the time knew how to grow cotton.
