The several rooms to the left of the atrium offer nothing remarkable. On the right, however, as will be evident upon inspecting the plan, a suite of apartments existed, carefully detached from the remainder of the house, and communicating only with the atrium by a single passage. The disposition and the ornaments of this portion of the house prove that it was a private _venereum_, a place, if not consecrated to the goddess from whom it derives its name, at least especially devoted to her service. The strictest privacy has been studied in its arrangements; no building overlooks it; the only entrance is closed by two doors, both of which we may conjecture, were never suffered to be open at once; and beside them was the apartment of a slave, whose duty was to act as porter and prevent intrusion. Passing the second door, the visitor found himself under a portico supported by octagonal columns, with a court or open area in the centre, and in the middle of it a small basin. At each end of the portico is a small cabinet, with appropriate paintings: in one of them a painting of Venus, Mars, and Cupid is conspicuous. The apartments were paved with marble, and the walls lined breast-high with the same material. A niche in the cabinet nearest the triclinium contained a small image, a gold vase, a gold coin, and twelve bronze medals of the reign of Vespasian; and near this spot were found eight small bronze columns, which appear to have formed part of a bed. In the adjoining lane four skeletons were found, apparently a female attended by three slaves; the tenant perhaps of this elegant apartment. Beside her was a round plate of silver, which probably was a mirror, together with several golden rings set with engraved stones, two ear-rings, and five bracelets of the same metal. Both cabinets had glazed windows, which commanded a view of the court and of each other; it is conjectured that they were provided with curtains. The court itself presents no trace of pavement, and, therefore, probably served as a garden. The ground of the wall is black, a color well calculated to set off doubtful complexions to the best advantage, while its sombre aspect is redeemed by a profusion of gold-colored ornament, in the most elegant taste. The columns were painted with the color called _sinopis Ponticum_, a species of red ochre of brilliant tint. Nearly all the wall of the court between the cabinets is occupied by a large painting of Actæon, from which the house derives one of its names; on either side it is flanked by the representation of a statue on a high pedestal. The centre piece comprises a double action. In one part we see a rocky grotto, in which Diana was bathing when the unwary hunter made his appearance above: in the other he is torn by his own dogs, a severe punishment for an unintentional intrusion. The background represents a wild and mountainous landscape. A painted frieze, and other paintings on the walls, complete the decorations of the portico.
