Rip and Cross Cut Block Column by David Nash at de Young Museum, San Francisco. Sycamore with chainsaw patination.
With hydraulic energy and the agricultural mechanics, the displacement of burdens remains in the 18th century a major technical problem. The artist who realised here a heavy manoeuvre did not leave a masterpiece of elegance. This model, which is part of unattributed objects, identifies payments in the collections under the Revolution and the Empire.
