In a past life, not so long ago, I wrote a dissertation about pilgrimage to Vijayangara, a 14th-16th century south Indian capital.The Vijaynagara Research Project website shows what an amazing place it is. Complexity and Economy in Pilgrimage Centers of the Vijayanagara Period is a paper I gave at the International Conference on Pilgrimage and Complexity, which included many very interesting talks. If you are really interested, you can find my book, Spiritual Journey, Imperial City, and I will be writing an entry on Architecture and Landscape in India for the 2nd edition of the Encyclopaedia of the History of Science, Technology and Medicine in Non-Western Cultures.
I could tell you how many steps make up the streets rising like stairways, and of the degree of the arcades' curves, and what kind of zinc scales cover the roofs; but I already know this would be the same as telling you nothing. The city does not consist of this, but of relationships between the measurements of its space and the events of its past...A description of Zaira as it is today should contain all Zaira's past. -Italo Calvino, Invisible Cities
