At the dawn of the 19th-century, the Prussian explorer Alexander von Humboldt was granted permission to charter an expedition to Spain's colonies in the New World. Over the course of five years, Humboldt would travel to the Orinoco and Amazon rivers, predict the agricultural and commercial potential of Cuba, climb higher in the Andes than anyone before him, and acknowledge the achievements of the ancient indigenous American civilizations. And he recorded it all in a series of diaries. On occasion of the 250th anniversary of Humboldt's birth, the drawings from these diaries are now available in a large format, slip-cased edition.
