The Heart of the Andes combined beauty with the most meticulous geological, botanical and scientific detail – it was Humboldt’s concept of interconnectedness writ large on canvas. The painting transported the viewer into the wilderness of South America. Church was, the New York Times declared, the ‘artistic Humboldt of the new world’. On 9 May, and unaware that Humboldt had died three days earlier, Church wrote to a friend that he planned to send the painting to Berlin to show the old man the ‘scenery which delighted his eyes sixty years ago’.
