BABesch 78 (2003) Zebrapatterns in Campanian wall painting: a matter of function Lara Laken Abstract Zebrapatterns are paintings with black and white stripes, usually covering the lower zone of a wall and often divided in panels reminiscent of marble imitation. They were in use in the Vesuvius area during the second half of the first century AD. Because they mainly appear in passage rooms, they have previously rarely been described and are generally thought to be secondary decoration, restricted to service areas. Thorough study of the pattern within its spatial context however leads to a different point of view: zebrapatterns were used in the first place to define public or common space. INTRODUCTION* only been found in the Vesuvian region.5 They are thus not only confined topographically, but also One of the first wall paintings that catches the eye chronologically, because they were all painted upon entering the excavations of Pompeii through before 79 AD. Within this region, they are found the modern entrance at the Porta Marina, is a pat- in different spaces from the other all-over pat- tern of black and white stripes. It is situated along terns. Therefore it seems worthwhile to discuss a stairway directly to the right of the main road them in a separate article.6 that leads through the city gate (fig. 1). These stairs belong to the so-called Villa Imperiale, a building TYPOLOGY discovered after a bombardment in 1943 that de- molished the Antiquarium above.1 Similar paint- The pattern usually appears as a high dado, some- ings are to be found across the street in an apart- times placed above a separate plinth, and varies ment complex linked to the Suburban Baths.

It is surprising that these kinds of paintings have been neglected by scholars for many years, and were rarely even described.2 These ‘zebrapatterns’ consist of a repeated sys- tem of black and white stripes oriented in vary- ing directions. Until recently they have always and exclusively been considered as secondary decoration, because they mainly appear in rooms with minor functions such as corridors, ramps, staircases and passages.3 Zebrapatterns are strongly linked to all-over patterns like checkerboard-pat- terns and geometrical and/or floral patterns.4 These repetitive patterns all appear in the same period: from about 50 to 79 AD. At this time, the Fourth Pompeian Style was flourishing, a typi- cally eclectic style of painting, in which many Fig. 1.

The same decoration was painted along the all-over patterns, zebrapatterns seem to be a truly stairs to the upper floor, as can be seen through the regional phenomenon.

The zebrapattern was [76], detail of W-wall: transition from middle to upper applied to both main and upper zone, and to the zone, and panel division in both zones. The vertical columns (photo: author). stripes (as well as the diagonal stripes) are straight (photo: author). An exception is found in the peristyle [32] in the Villa of Oplontis (fig. 2). Here the pattern was applied to the entire wall and even to the ceiling8 and columns, in panels of differing proportions of which the arrangement is reminiscent of the First and early Second Pompeian Styles: dado, orthostates and isodomic courses.9 Corridors [76] and [46] in Oplontis are slightly incongruous as well, because these have upper zones decorated with a common, although simple, Fourth Style system (figs. 3-4). The strokes in the zebrapatterns are either wavy or straight.10 Different variants occur next to each other, in large quantities, in the Villa of Oplontis. In the peristyle [32] of this villa, panels with waves even alternate with panels of straight stripes. Based on this, it is hard to determine any chronological development of the patterns; they do not appear to become more and more schematic over time. Not all zebrapatterns are divided into panels; sometimes the pattern continues without any interruption. Such is the case in the corridors of two large public buildings: the porticus of the Palaestra in Herculaneum and the gallery of the Amphitheatre in Pompeii. In the first, the strokes fan out like the leaves of big plants (fig. 5); on the south wall they even start bending (fig. 6). The same system is found in the continuous decora- tion along a staircase in the Casa del Bracciale d’Oro in Pompeii (VI 17,42, fig. 7) and in corridor [26] of the so-called Villa of Ariadne in Stabiae. In the Amphitheatre, on the other hand, the strokes Fig. 4. Oplontis, so-called Villa of Poppaea, corridor all point towards the right (fig. 8). This kind of [46], dado, main and upper zone (N-wall).

For most of these continuous patterns the strokes are always straight, but at the upper sto- ries of the Suburban Baths, the one continuous pattern in corridor [22] has waves, like all other zebrapatterns in this apartment complex. Also in the Casa dell’Albergo the pattern may have had a wavy system, at least it looks as if the white paint was wavy, but it is too worn to tell now. ORIGIN As all four Pompeian styles are mainly based upon imitations of either a certain material, or an archi- tectural system, a famous mythological painting or sculptural group (mostly Greek masterpieces), logically one of the first questions that comes to mind when studying Roman wall painting, is what source inspired the painter.

Some zebrapanels have a white to suggest the graining of wood. In this case, an inner line, which usually suggests projection and imitation of timber framing, as was once suggested therefore points to a relation to stone. However, to me by E.M.
