Let me begin, very obliquely, with the Grand Canyon and the paradox of trying to see beyond cultural or historical precedent.
The first European to look into the depths of the great gorge was the conquistador Garcia Lopez de Cardenas in 1540. He was horrified by the sight and quickly retreated from the South Rim. More than three centuries passed before Lieutenant Joseph Christmas Ives of the U.S. Army Corps of Topographical Engineers led the second major expedition to the rim. Like Garcia Lopez, he recorded an "awe that was almost painful to behold." Ives's expedition included a well-known German artist, but his sketch of the Canyon was wildly distorted, almost hysterical.
Neither the conquistadors nor the Army engineers, in other words, could make sense of what they saw; they were simply overwhelmed by unexpected revelation. In a fundamental sense, they were blind because they lacked the concepts necessary to organize a coherent vision of an utterly new landscape.
