What is the name of the room that contains a bust of Aelius Verus?
Inside the house, the Palladian form reaches a height and grandeur seldom seen in any other house in England. It has, in fact, been described as "The finest Palladian interior in England." The grandeur of the interior is obtained with an absence of excessive ornament, and reflects Kent's career-long taste for "the eloquence of a plain surface". Work on the interiors ran from 1739 to 1773. The first habitable rooms were in the family wing and were in use from 1740, the Long Library being the first major interior completed in 1741. Among the last to be completed and entirely under Lady Leicester's supervision is the Chapel with its alabaster reredos. The house is entered through the Marble Hall (though the chief building fabric is in fact pink Derbyshire alabaster), modelled by Kent on a Roman basilica. The room is over 50 feet (15 m) from floor to ceiling and is dominated by the broad white marble flight of steps leading to the surrounding gallery, or peristyle: here alabaster Ionic columns support the coffered, gilded ceiling, copied from a design by Inigo Jones, inspired by the Pantheon in Rome. The fluted columns are thought to be replicas of those in the Temple of Fortuna Virilis, also in Rome. Around the hall are statues in niches; these are predominantly plaster copies of classical deities.
The hall's flight of steps lead to the piano nobile and state rooms. The grandest, the Saloon, is situated immediately behind the great portico, with its walls lined with patterned red caffoy (a mixture of wool, linen and silk) and a coffered, gilded ceiling. In this room hangs Rubens's Return from Egypt. On his Grand Tour, the Earl acquired a collection of Roman copies of Greek and Roman sculpture which is contained in the extensive Statue Gallery, which runs the full length of the house north to south. The North Dining Room, a cube room of 27 feet (8.2 m) contains an Axminster carpet that perfectly mirrors the pattern of the ceiling above. A bust of Aelius Verus, set in a niche in the wall of this room, was found during the restoration at Nettuno. A classical apse gives the room an almost temple air. The apse in fact, contains concealed access to the labyrinth of corridors and narrow stairs that lead to the distant kitchens and service areas of the house. Each corner of the east side of the principal block contains a square salon lit by a huge Venetian window, one of them—the Landscape Room—hung with paintings by Claude Lorrain and Gaspar Poussin. All of the major state rooms have symmetrical walls, even where this involves matching real with false doors. The major rooms also have elaborate white and multi-coloured marble fireplaces, most with carvings and sculpture, mainly the work of Thomas Carter, though Joseph Pickford carved the fireplace in the Statue Gallery.  Much of the furniture in the state rooms was also designed by William Kent, in a stately classicising baroque manner.
