The initial design of Thomas Jefferson's Monticello was taken from the Villa Cornaro in Piombino Dese, Italy, in Book II, Chapter XV of "I Quattro Libri dell'Architettura", but this façade was later covered up by Jefferson's own expansions to his house. Thomas Jefferson made two drawings of the Hammond–Harwood House when he served the government in Annapolis in 1783–1784. One could assume that Jefferson recognized the house as derived from Palladio because his knowledge of "The Four Books of Architecture" was extensive. He referred to the book as his architectural "bible" and the plate of the Villa Cornaro follows the Villa Pisani plate; and directly opposite the Villa Cornaro in some 18th-century English transcriptions of the work.
