When Hernan Cortes met the Mayans, Aztecs and other cultures of the gulf coast of Mexico in 1519, it was the first extended contact between the peoples of continental America and Europe. The Spanish found cities larger and better run than any in Europe, and pyramids greater than Egypt's. The Aztecs believed time was running down and they lived in the final age of the world. Many Spaniards believed Christ's millennium was approaching, and God's revelation of Americas had opened the final act: the conversion of the remote races of the earth. After the Day of Judgement God's experiment with man would be over, and the laboratory, the physical world, would be destroyed. Both cultures were acting out the last days. John Harrison follows Cortes' route along the Mexican coast and across country to modern Mexico City, home of the Aztecs
