2. Interiors The villa's interiors are arranged over five floors, each floor designed for a different function. The main rooms are located on the first floor or piano nobile , where a large central loggia (now glazed in) looks down over the town, its main street and the surrounding countryside. This hall is known as the Room of Hercules on account of its fresco decorations , and was used as a summer dining hall. It has a grotto -like fountain with sculpture at one end. To either side of the loggia are two circular rooms: one is the chapel, the other accommodates the principal staircase or Scala Regia , a graceful spiral of steps supported by pairs of Ionic columns rising up through three floors and frescoed by Antonio Tempesta .The two grand apartments at first floor level are symmetrically-matched in plan and complete the remaining enclosure of the courtyard. Each has a series of five rooms with state rooms , which begin with the largest reception hall nearest the entrance and proceed, with increasing intimacy and decreased size, to a bedroom, wardrobe and studiolo at the northern end; an ordered suite that would become standardized in the 17th century as the Baroque state apartment . The different orientations of these two apartments allows for a seasonal differentiation; the east, or summer apartment is associated with the active life, the west, or winter range with the contemplative life. [7] The scrupulous symmetrical balance of the two apartments is carried through by their matching parterre gardens, each reached by a bridge across the moat and cut into the hillslope.The suites are famous for their Mannerist frescoes. The iconograhic program of frescoes expressing the glory of the Farnese were worked out by the humanists in Farnese's court, notably his secretary, Annibale Caro ; [8] The fresco cycles portray the exploits of Alexander the Great , and of course of the Farnese themselves: in the Sala dei Fasti Farnesiani (the Room of Farnese Deeds), decorated by the brothers Taddeo and Federico Zuccari , the Farnese are depicted at all their most glorious moments, from floor to coffered ceiling. [9] Other artists employed in fresco decoration include Giacomo Zanguidi (il Bertoia), Raffaellino da Reggio , Antonio Tempesta , Giacomo del Duca , and Giovanni De Vecchi .Among the frescoed subjects of the contemplative winter suite is the famous "Room of the World Map" or Sala del Mappamondo , displaying the whole known world as it was in 1574 when the frescoes were completed.
