The upper division tends more and more to be represented as an open space, behind the plane of projection in which the main part appears. Thus in [Plate XII] we see on either side a silver vase with fruits and vine leaves, standing on the cornice of the main wall, in the open. Often the upper space is painted blue, as if one caught a glimpse of the sky above the wall; sometimes the outline of a wall further beyond is seen, or columns in the rear connected with those in front by a decorative framework; and not infrequently small architectural designs, in perspective, rest upon the cornice where the vases are shown in our plate. But in all the designs of this style, complex as well as simple, the threefold division of the wall carried over from the first style is retained; very often the distinction between the base, main wall, and upper portion is emphasized by painting them so that they seem to be in three planes of projection.
The ornamental framework for the painting, consistently with the architectural character of the decoration as a whole, is generally conceived as a pavilion projecting from the wall; so in [Plate XII], where we see two columns sustaining a roof, upon the front of which winged figures stand, each with a hand extended upward to the entablature of the large pillars at the sides. The design of the pavilion is suggested by that of a shrine, such a shrine as the one in the apse of the sanctuary of the City Lares ([Fig. 41]).
This conception is here borne out by the subject of the painting, which represents a statue of Dionysus resting, ivy-crowned, with a thyrsus in his left hand; the right hand is thrown gracefully over the head, and at the feet of the god the lifelike figure of a panther is seen. The round high pedestal supporting the group is in the open, and the background affords a charming vista among the trees.
This framing of the principal painting led further to the division of the body of the wall vertically into three sections, a broad central section, included within the outline of the pavilion, and two panels, one at each side. The arrangement is well illustrated in our plate, the side panels of which are adorned with painted statues of tastefully draped figures, one of them holding a lyre. The later styles of decoration retained this symmetrical division of the wall space, which made prominent the picture of greatest interest without detracting from the finish of the decorative setting; but in the fourth style it is often obscured by the intricacy of the designs.
The third style came into vogue during the reign of Augustus, and was prevalent until about 50 A.D.; we shall call it the Ornate Style, from its free use of ornament. It was developed out of the second style in the same way that the second style was developed out of the first; but the transition was not accomplished at Pompeii, which, like the provincial cities of our day, received its fashions from the great centres.
The characteristics of the Ornate Style, as regards both the main design and the ornamentation, may easily be perceived from the example presented in [Fig. 263], especially if this is viewed in contrast with the specimen of the preceding style shown in [Plate XII]. The architectural design has now lost all semblance of real construction. Columns, entablatures, and other members are treated conventionally, as subordinate parts of a decorative scheme; they are, with few exceptions, reduced to narrow bands or stripes of color dividing the surface of the wall. The elaborate border of the central painting suggests a pavilion, yet the projecting base, which in the second style gave this design its significance, is lacking. Hardly less noteworthy is the treatment of the upper portion of the wall. Fanciful architectural forms and various ornaments stand out against a white background, suggestive of the open sky; yet in our example, as often in this style, there is no organic connection between the decoration of the main part of the wall and that of the ceiling.
Every part of the framework of the third style is profusely ornamented. The ornamental system is seen to have a certain affinity with that of Egypt, and Egyptian figures occasionally appear; whence we infer that it was developed in Alexandria. Early in the reign of Augustus, in consequence of the relations with Egypt following the battle of Actium, a new impulse may well have been given to the introduction into Italy of Alexandrian art.
The specimen of the third style shown in [Fig. 263] is from the beautiful decoration of the house of Spurius Mesor, portions of which are well preserved. The base of our specimen consists of two parts, a lower border and a broad stripe of black divided into sections of different shapes and sizes by lines of light color. In the small sections ornaments are seen painted in delicate shades, two of them being faces.
The large painting presents a mythological scene, but the subject is not clear. The priestess seems to be performing a ceremony of expiation in order to free from the taint of some crime the young man who, with a wreath on his head and a sword, pointed downward, in his right hand, bends over the hind just slain as a sacrifice. The colors are subdued and effective; the painting from the technical point of view is among the best found at Pompeii.
Around the painting are narrow black stripes separated by white lines; in the broader stripe underneath, between the columns, are two light blue birds upon a dull red ground. The small squares in the flat cornice above are of many colors, shades of green, pink, and brown predominating. The broad panels on either side of the painting are of the color often called Pompeian red; they have an ornamented border, and a small winged figure in the centre. The stripe below these shows vases and other ornaments on an orange-yellow ground; that above, interrupted by the cornice over the painting, is black, with various ornaments, as baskets of fruit, sistrums, and geese, painted in neutral colors. Among the ornaments of the upper part of the wall, festoons of leaves, vines, vases, parrots, and griffins can be distinguished, painted in light shades of brown, blue, green, and yellow.
