A Palace at the Top of the World ; the Incas May Be Gone, but Their Vistas Still Take Our Breath Away

Article excerpt

In the mountains of Peru, entire cities have been lost since they were abandoned by the last Incas five centuries ago. Hugh Thomson - young, British, and with no idea what he wanted to do with his life - found the idea of discovering one irresistible.

Thomson takes us with him on his "Exploration of the Inca Heartland," where he succeeds in putting several lost sites in their rightful places on the map. But the quest soon becomes far more ambitious than an effort to locate ruined cities by traversing roadless mountains in landslide country, or pushing through tropical forests so lush that a hiker can pass within a few feet of a large stone building without seeing it.

Thomson casts his book as a travel memoir, and it would make an interesting read if it were no more than that, but it is much, much more. Belying his casual, kid-with-a-backpack approach, Thomson reveals a sophisticated grasp of Andean history, a canny understanding of the complex encounter between Indian and Spaniard, and a firm grasp of the interaction between human society and the Peruvian mountains.

The Cobos family, two generations of whose members guide Thomson's explorations, follow the ancient Andean practice of having a farm at 10,000 feet, and another in the tropical forest. They move regularly between the two, bringing mountain-grown grain and potatoes to their lowland farmhouses, and carrying fruit upslope.

The Incas were ruthless conquerors. But Thomson argues that despite their undoubted prowess at arms, the imperial success of the Incas was the result, less of might than of the fact, that within their vast empire the rule of law and an excellent road system allowed the peoples they subjugated to exchange the produce of the high mountains for the fruits of the humid lowlands. Is it better to be independent, or to be well-housed, well-clothed, and well-fed? he asks.

Well-built in stone, Inca roads still traverse the Andes. Unlike European roads that zigzag up mountains to enable horses to walk up a gradual incline, these Inca roads are dizzying ascents of hundreds of stone steps leading straight to the top. Llamas can climb stairs.

Pack animals, meat supply, and providers of fine wool, llamas fed the Incas, clothed them, and provided the transport that made empire possible. Llamas were the muscle and fiber of the empire, and they flourish on the grasses of high Andean pastures. This explains why it was practical for the Incas to have their capital at Cuzco, even though at 11,207 feet above sea level many visitors suffer altitude sickness.

An emperor can put his summer palace anywhere he likes, so why did the Incas build Machu Picchu on a remote mountain top? Visitors reach the 13,000-foot-high site after a long climb up a breathtaking flight of stairs. …
