An important paper - given the painstaking analysis of data - which shows just how careful one has to be in attributing the demise of the Indus civilization to climate change.
On his ninth death anniversary, a tribute to the American archaeologist Gregory M. Possehl, one of the most prolific writers on the ancient Indus civilization – no less than eight books by Possehl are listed on this site, many of them massive tomes, covering all aspects of Indus civilization.
The apparently sudden appearance of Indus-type seals, pottery and other implements around 2000 BCE in the Arabian Gulf, just before the Indus cities and culture seems to have gone into decline, is a great mystery.
An insightful paper that covers a lot of important ground: a brief history of Indus discoveries and excavations in Gujarat, a look at the core vs. periphery model of cultural expansion that has been used to theorize that Indus people from Sindh moved into Gujarat.
Rita P. Wright, an archaeologist with long experience understanding the Indus areas around Harappa (see the Beas Settlement and Land Survey) looks at the complex evidence surrounding the decline of Indus civilization at the end of the third and beginning of the second millennium (around 2000 BCE and afterwards).
The authors take on the complex question of how Harappan or Indus culture made its presence felt in Gujarat from about the middle of the third millennium through the decline of Indus civilization six or seven hundred years later. How did Indus traditions as expressed in material culture and the manufacture of these objects relate to what we see in Indus cities like Mohenjo-daro and Harappa?
A discussion of some of the approaches meta-issues that arise when investigating raw materials, their locations and histories of their exploitation and how these can be interpreted. Particular attention is paid to carnelian and the history of possible sources in Gujarat.
The geography and land use of the Little Rann of Kutch, a salt marsh area, is discussed as a possible source of raw material in ancient Harappan times.
