The shops with their upper floors, _pergulae_, were nineteen feet high. When the shutters were up they presented a monotonous appearance (Fig. 139), but on sunny days, when the articles offered for sale were attractively displayed, and buyers and idlers were loitering in front or leisurely passing from one to the other, shops and street alike were full of color and animation. [Illustration: Fig. 139.--Façade of the house of the Faun, restored. At the left, the front of a shop (1 on the plan) with its upper floor; then the large front door, two shops, the entrance of the smaller atrium and the fourth shop, which, like the second, is completely closed by shutters.] The floor of the fauces, as of many of the other rooms, is rich in color. It is made of small triangular pieces of marble and slate--red, yellow, green, white, and black. At the inner end it was marked off from the floor of the atrium by a stripe of finely executed mosaic, suggestive of a threshold (Fig. 140), now in the Naples Museum. Two tragic masks are realistically outlined, appearing in the midst of fruits, flowers, and garlands, the details of which are worked out with much skill. [Illustration: Fig. 140.--Border of mosaic with tragic masks, fruits, flowers, and garlands, at the inner end of the fauces.] The walls of the fauces are ornamented in an unusual manner. The ordinary decoration of the first style is carried to the height of eight feet. Above this on either side projects a tufa shelf about sixteen inches wide, on which is placed the façade of a diminutive temple; that on the left is seen in Fig. 141. The front of the cella, with closed doors, is presented in relief, but the four columns of the portico stand free. The shelf is supported underneath by a cornice which rested originally on stucco brackets in the shape of dogs; the underside is carved to represent a richly ornamented coffered ceiling. The atrium was a room of imposing dimensions. The length is approximately 53 feet, the breadth 33; the height, as indicated by the remains of the walls and the pilasters, was certainly not less than 28 feet. Above was a coffered ceiling. The sombre shade of the floor, paved with small pieces of dark slate, formed an effective contrast with the white limestone edge and brilliant inner surface of the shallow impluvium, covered with pieces of colored marbles similar to those in the fauces. Still more marked was the contrast in the strong colors of the walls. Below was a broad surface of black; then a projecting white dentil cornice, and above this, masses of dark red, bluish green, and yellow. The decoration, as usual in the first style, was not carried to the ceiling, but stopped just above the side doors; the upper part of the wall was left in the white.
