The politician and architect Thomas Jefferson (1743–1826) once referred to Palladio's " Quattro libri" as his bible. Jefferson acquired an intense appreciation of Palladio's architectural concepts, and his designs for his own beloved Monticello, the James Barbour Barboursville estate, Virginia State Capitol, and the University of Virginia were based on drawings from Palladio's book. Realizing the powerful political significance pertaining to ancient Roman buildings, Jefferson designed his civic buildings in the Palladian style. Monticello (remodelled between 1796 and 1808) is quite clearly based on Palladio's Villa Capra, however, with modifications, in a style which is described in America today as Colonial Georgian. Jefferson's Pantheon or Rotunda at the University of Virginia is undeniably Palladian in concept and style.
