The Roman Villa del Casale is a late-ancient residential building, popularly defined as a villa despite not having the characteristics of the Roman villa, whose remains are located about four kilometers from Piazza Armerina, in Sicily. Since 1997 it is part of the UNESCO World Heritage Sites. The discovery of the villa dates back to 1950, following the reports of the inhabitants of the place. Based mainly on the style of mosaics, a large house, built on an older farm. monumental entrance to three arches with a horseshoe-shaped courtyard (rooms 1-2); central body of the villa, organized around a quadrangular peristyle court, with a garden with a mystical basin in the center (rooms 8-39); large trichora preceded by an ovoid peristyle surrounded in turn by another group of rooms (rooms 47-55) thermal complex, with access from the north-western corner of the quadrangular peristyle (rooms 40-46). Each of the four nucleus of the villa is arranged according to its own directional axis. However, all the axes converge at the center of the quadrangular peristyle tank. The function of the rooms is almost always suggested by allusions in the floor mosaics. The division into three distinct nuclei, also from the point of view of the axes. The great functionality was linked to an exasperated search of perspective effects and plans with curved lines. The succession vestibule-court-narthex-apsidal hall, with a remarkable interchangeability, resumed as a system of the Christian basilicas and, later, of the Arab mosques. The villa, is not an isolated type in Piazza Armerina, but, besides being documented in another villasiciliana near Noto, has precise correspondences in African villas and owes its original model to the Villa Adriana of Tivoli. Access to the residence took place through a passage with three arches, decorated with fountains and military paintings, which closely resembles a triumphal arch. The horseshoe-shaped courtyard is surrounded by marble columns with Ionic capitals, in the center are the remains of a square fountain. On the western side of the courtyard there was a latrine. At the entrance a few steps lead to the vestibule: a partially preserved adventus scene is inserted in the middle of a geometric floor. In the upper register a man with a crown of leaves on his head and a candlestick in his right hand, flanked by two young men with twigs in his hand. From the vestibule to the peristyle: the mosaic presents here a series of laurel wreaths including heads of animals of many different species (felines, antelopes, bulls, wild goats, horses, onagers, deer, rams, an elephant and an ostrich). At the center of the peristyle there was a large fountain: two semi-circular tanks with the curved side facing symmetrically in the center framed an elongated rectangular basin with two arches on the longer sides. In line with the vestibule, there is a small apse compartment, the "Sacello dei Lari", framed by two columns of the peristyle and with a geometric mosaic floor. The ivy leaf, Dionysian symbol and decorative motif of Sasanian ancestry. On either side of the basilica there are two master apartments on the "Grande Caccia" corridor, consisting of a horseshoe peristyle with four Ionic columns and a fountain in the center. In the antechamber, the mosaic with the combat of Eros and Pan, in which the turtle symbolizes evil, the cock the good and the light; in the cubicle is the mosaic of Eroti Cacciatori, in medieval iconography depicts the Sloth. From the monumental entrance of the villa one could access a thermal complex. The first room, equipped with quays, and probably used as a dressing room is decorated with a floor mosaic that depicts the landlady with her two sons flanked by maids. It follows the traditional sequence of Roman thermal environments, with frigidarium, tepidarium and calidarium.
