Certain letters in the National Archives between Brumidi and United States officials shed interesting light on the 1862 negotiations relative to the Dome Canopy. Extracts from these letters follow: From Tho. U. Walter, “architect of extension and new Dome,” to Constantino Brumidi, August 18, 1862: “It is intended to have a picture 65 ft. in diameter painted in fresco on the concave canopy over the eye of the New Dome. I would thank you to furnish me with a design for the said picture at your earliest convenience.... You will also submit with the design an estimate of the cost of executing it in real fresco painted on the fresh mortar.” From Constantino Brumidi to Tho. U. Walter, September 8, 1862. “...I herewith submit to you my design for the fresco picture to be painted on the Canopy of the New Dome of the United States Capitol. The six groups around the border represent, as you will see, War, Science, Navigation, Commerce, Manufacture and Agriculture. The leading figures will measure some 15 feet. In the center is an apotheosis of Washington surrounded by allegorical figures of eminent men of the times of Washington, which latter will be likenesses. “As this picture will be seen at a height of 180 ft. the painting must be of the most decided character possible. It will cover 4664 sq. ft. and will be worth $50,000 to execute it including the necessary cartoons and every expense pertaining to the painting.” From Tho. U. Walter to Constantino Brumidi, December 24, 1862. “Your letter of the 8th of September was duly received, together with your design for the proposed picture in fresco, for the canopy over the eye of the New Dome of the United States Capitol. The design meets my entire approval. It has also the approval of Major B. B. French, the Commissioner of Public Buildings. I sent it to the residence of the Hon. Caleb B. Smith, the Secretary of the Interior, where it has been for several weeks. Mr. Smith also expresses himself entirely satisfied with the design. I am therefore free to give it my official approval with but one condition and that is that you will consent to execute it at a greatly reduced cost. “I am aware, as you have expressed to me in conversation that there is no picture in the world that will compare with this in magnitude and in difficulty of execution, being painted on a concave surface, and I am also aware that it covers about eight times more surface than Mr. Lentze’s picture which cost $20,000. But in view of the exigencies of the times I do not consider that we would be justified in expending so large a sum as $50,000. “Should you execute this work it will be the great work of your life: it will therefore be worth on your part some sacrifice to accomplish so great an achievement....”
