Download or read book Machu Picchu written by Johan Reinhard and published by Cotsen Institute of Archaeology Press. This book was released on 2007-12-31 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Machu Picchu, recently voted one of the New Wonders of the World, is one of the world's most famous archaeological sites, yet it remains a mystery. Even the most basic questions are still unanswered: What was its meaning and why was it built in such a difficult location? Renowned explorer Johan Reinhard attempts to answer such elusive questions from the perspectives of sacred landscape and archaeoastronomy. Using information gathered from historical, archaeological, and ethnographical sources, Reinhard demonstrates how the site is situated in the center of sacred mountains and associated with a sacred river, which is in turn symbolically linked with the sun's passage. Taken together, these features meant that Machu Picchu formed a cosmological, hydrological, and sacred geological center for a vast region.

Download or read book Inca Land written by Hiram Bingham and published by Lulu.com. This book was released on 2017-08-26 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The builders were not in search of fields. There is so little arable land here that every square yard of earth had to be terraced in order to provide food for the inhabitants. They were not looking for comfort or convenience. Safety was their primary consideration. They were sufficiently civilized to practice intensive agriculture, sufficiently skillful to equal the best masonry the world has ever seen, sufficiently ingenious to make delicate bronzes, and sufficiently advanced in art to realize the beauty of simplicity. What could have induced such a people to select this remote fastness of the Andes, with all its disadvantages, as the site for their capital, unless they were fleeing from powerful enemies."

Download or read book The City is My Canvas written by Richard Haas and published by Prestel Publishing. This book was released on 2001 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary trompe l'oeil artist Richard Haas transforms the drab exteriors of neglected buildings into breath-taking facades. The City Is My Canvas documents his most important projects of the last two decades in lavish double-page spreads which illustrate the "before" and "after" phases of each site. From Italian Quadrata paintings to Baroque and Rococo interiors, trompe l'oeil murals have a long tradition as decoration and didactic illustration. Muralist Richard Haas brings this tradition into the 21st-century as he revitalizes forgotten buildings in eroding city centers by creating new "false" facades that seamlessly blend into the existing environment. "The world is constantly changing, and the needs of the city change with it", says Haas. "Even if blank urban walls at key locations of the city are now primarily seen as opportunities for computer-generated advertisements, whole segments of the mid-range urban American landscape and large areas of our edge cities remain in drastic need of refinement, softening, and improvement".
