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.
An overview of the important technological and organization aspects of the carnelian bead industry that will be useful in developing interpretive models regarding the role of agate bead production in early urban societies.
Khambhat in Gujarat province provides a unique opportunity to study the organization of a specialized craft and understand how different aspects of social, economic and political organization relating to such crafts might be reflected in the archaeological record because of the long continuity of bead-making in this region,
Recent explorations in the peripheral regions east of the Indus valley have established the spread of Harappan culture to settlements in Kutch, Saurashtra, Rajasthan and Harayana, but there has been much speculation on the reasons behind this cultural expansion.
