" In the summer of 1911, the explorer Hiram Bingham III bushwhacked his way to a high ridge in the Andes of Peru and beheld a dreamscape out of the past. There, set against looming peaks cloaked in snow and wreathed in clouds, 5 was Machu Picchu, the famous “lost city” of the Incas. This expression, popularized by Bingham, served as a magical elixir for rundown imaginations. The words evoked the romanticism of exploration and archaeology at the time."
