The artistic treasure of a major research expedition: This lavish volume in a decorative slipcase brings together for the first time all the drawings and sketches from Alexander von Humboldt's diaries of his great expedition to America. One of Humboldt's most significant undertakings was his extensive research journey to America between 1799 and 1804, during which he documented his comprehensive observations in diaries. He filled nearly 4,000 pages with detailed written accounts as well as hundreds of drawings, ranging from animal and plant sketches to geometric studies. Organized by subject matter and accompanied by explanatory comments and diary excerpts, the illustrations are presented in their original format in facsimile quality. In its completeness, this previously undiscovered artistic treasure represents an inexhaustible source of knowledge and reveals an entirely new facet.
