Gaudenzio Marconi (1841-1885), Auguste Neyt, 22-yr-old model for the sculpture L’age d’airain (The Age of Bronze) by Auguste Rodin (1877).
Original photos, now part of the Rodin archives in the Musée Rodin in Paris, show the remarkable likeness between Neyt and the final sculpture. In these photos, a long spear was held upright in his left hand. The spear was soon dropped.
