"Exterior Order. Extension of U.S. Capitol," by Thomas U. Walter, 1854
A good example of Thomas U. Walter's exquisite draftsmanship, this drawing illustrates the elements, proportion, and dimensions of the Capitol's exterior order. By necessity, it matched the Corinthian order already employed on the outside of the Capitol by previous architects William Thornton, B. Henry Latrobe, and Charles Bulfinch.
