From Constantino Brumidi to Tho. U. Walter, December 27, 1862: “...I have come to the conclusion to expedite a settlement as to the price of the painting to be executed on the canopy over the eye of the Dome of the United States Capitol by reducing my offer to $40,000, which is lower, considering the subject, the curved form of the surface on which it is to be painted and the square feet of painting it contains than any real fresco picture ever painted....”
From Tho. U. Walter to B. B. French, “Distributing Agent of United States Capitol,” December 29, 1862: “...I consider the price ($40,000) exceedingly low in view of the fact that it contains 4664 square feet, that it is all to be painted on a curved surface, and that Mr. Brumidi is the only real fresco painter in this country capable of executing the work. The design is probably the grandest and most imposing that has ever been executed in the world and Mr. Brumidi has proved by his real frescoes in the Capitol extension (all of which were painted by his own hand) that he is fully equal to the task. The grandeur of this picture, the great distance at which it will be seen, and the peculiarity of its light will render it intensely imposing.”
From B. B. French to Tho. U. Walter, January 5, 1863: “...as there is confessedly no artist in the United States, capable of executing a real fresco painting as it should be done, especially so important a work as the one in contemplation, except Mr. Brumidi, and, as we know from experience his excellence in that art, I do not see how we can do otherwise than employ him....”
From Tho. U. Walter to Constantino Brumidi, March 11, 1863. “...I have the honor to inform you that your design for painting the Canopy over the eye of the aforesaid new Dome is adopted. And, inasmuch as Congress has made the appropriation for the completion of that work you are hereby authorized to proceed at once with the aforesaid canopy painting....”
Two letters, one from the Department of the Interior to the Capitol Dispensing Agent and the other from the Architect of the Capitol to the Department of the Interior should be quoted at this time as they verify amounts paid the artist and the length of time used in the actual painting of the Dome canopy.
From J. P. Usher, Secretary of Interior, dated Nov. 6, 1863.
“...$10,000, one fourth the entire cost of the work (for painting the canopy over the eye of the new dome of the Capitol in real fresco), has already been paid to Mr. Brumidi. I am of the opinion that the progress which has been made does not justify any further payments at present. You will therefore suspend any advances to Mr. Brumidi until further orders.”
From Thomas U. Walter, Architect U. S. Capitol, dated December 3, 1864.
“As the canopy for the picture over the eye of the new dome is ready for Mr. Brumidi and as he is now about to commence to work, I deem it proper to say that he has not received any payment on account of his contract since November 6, 1863, and that in the interim he has been occupied in perfecting the full-size cartoons, which are now ready for the work. I, therefore, respectfully recommend that payments to him be resumed in accordance with his contract and that they be continued as the work progresses until he shall have received the aggregate sum of $30,000, after which no further payments to be made until the work is completed and approved.”
In the Annual Report dated November 1, 1865, of Edward Clark, Architect of the Capitol (1865-1902), we find reference to the completion of the canopy:
