Stock Photo - Roman fresco wall decorations of Viridarium L of the Villa Farnesia, Rome. Museo Nazionale Romano ( National Roman Museum), Rome, Italy. Against a black background. . . Rooms B and D, clearly bedrooms (cubicula), were symmetrically arranged and projected farther forward than the large room C (the triclinium). They opened onto a rectangular unroofed space that must have been a garden (viridarium). This was a genuine hortus conclusus (enclosed garden). The walls that surrounded the real garden were decorated with a painted garden, like an extension of the real one. The south wall was decorated with the three panels shown here: within dense vegetation there are huts made of reeds, jetting fountains, and a marble seat. The most complete example of this kind of room is the one from the Villa of Livia (on display on this floor of the museum), the prototype for the fashion that spread throughout the Roman world of painting gardens on interior walls and around real garden spaces.
