Threshold Pavements

While preparing for a vacation in Sicily I noted William Tronzo's discussion of the lozenge motif in the opus sectile pavement of the twelfth-century Cappella Palatina in Palermo (a lozenge is a rhombus one axis of which is longer than the other, oriented so that its axes are parallel to the sides of the enclosing field). Tronzo believes that the pavement of the south aisle includes designs related to the route the visitor was intended to take through the building. The designs of the two westernmost bays appear significant, as they break the otherwise consistent symmetry of the pavement. In the westernmost bay, the one a visitor enters today (and on Tronzo's showing the original public entry point), there is an arrangement of five circles flanked by checkered bands. Tronzo argues that this design marks a threshold.1 The next bay toward the altar in the south aisle is decorated with a lozenge filled with circles and developed into circles in the outer corners of the rectangle enclosing it. This is the only lozenge in the pavement and, so far as I can tell, the only lozenge in the building's entire decoration. Tronzo interprets this decoration, too, as a threshold, and contends that “taken together, these patterns may be seen as inscribing a path of movement through the chapel, from a point of entry at the southwest, down the south aisle one bay and into the nave.” The need for two thresholds comes about because the platform at the west end of the nave blocked access to the nave from the entry bay.

Tronzo cites as comparative evidence the occurrence of such “threshold pavements”, characterized by “central elements and narrower flanking bands”, in Antique and medieval buildings at entrances. One of his examples, from Pompeii, has as its central element a bichrome lozenge.2 He also draws attention to the use of patterns to mark significant points in a processional route in “a group of ecclesiastical pavements from Rome and Monte Cassino from the later Middle Ages” and the use of porphyry disks for the same purpose in the Great Palace in Constantinople.3 Perhaps the lozenge in the second bay in the south aisle of the Cappella Palatina, which has no flanking bands, might be interpreted slightly differently: not as a threshold but as marking a place to stand, stop, or wait.

It occurred to me to look for lozenges on thresholds in Umayyad architecture, and the pavement of the bath of Khirbat al-Mafjar was the first place I looked.

Khirbat al-Mafjar

Khirbat al-Mafjar, in Palestine near Arîhâ (Jericho), was built in the second quarter of the eighth century A.D. and consists of an unfinished palace and an apparently earlier bath that had been completed and used before the whole complex was destroyed in a mid-century earthquake. The bath has an outsized main hall with a remarkably preserved mosaic floor that has been the subject of much discussion. The structure was composed of nine bays on sixteen piers surrounded by aisles the bays of which were developed into apses. The public entry was in the center of the east side, a private entry from the palace was in the southwest, the three apses on the south side and the aisle in front of them were enclosed by a raised pool, the hot rooms and latrine were on the north, and at the northwest corner was a richly decorated audience hall. The center apse on the west side was marked by a special design in a border strip in its pavement, interpreted variously as a picture-puzzle or a rebus, and a curious stone chain that hung from its frontal arch: this was evidently a place for the owner to sit in audience or view proceedings in the main hall.

Lozenges in the Pavement

The fields of the mosaic pavement, except those in the apses and the audience hall, were designated “panels” by the excavator, Robert W. Hamilton. Very generally and disregarding the border designs, each bay and each space between piers contains one panel, or rectangular field of geometric decoration, while the aisles are treated as continuous fields; each apse has its own decoration, as does the audience hall. The central bay and those on axis with it are larger than the others, and the pavements of the central bay and the four bays in the corners of the nine-bay zone, all of which were domed (see below), are marked by large circular designs, the central one being outsized. There are two exceptions to this scheme, which I shall discuss below.

One need not look far for lozenges. The threshold between the portal and the interior (immediately east of panel 1, which stretches the length of the eastern aisle) is decorated with a lozenge the left and right corners of which develop into knots that may be considered similar to flanking bands.4 Another lozenge appears on the threshold to the audience hall5 without flanking bands, which may indicate either that in this context the lozenge itself bore a connotation of threshold or that, as in Palermo, in an interior context the significance of the lozenge was to mark a spot to stand, stop, or wait. (In either case, the occurrence of these lozenges in these locations has led me to accept Tronzo's remarks on “threshold pavements” without further investigation.)

Surprisingly, a somewhat similar lozenge is floated on the pattern of panel 18, just north of the central circle and facing the central axis of the large pool (Hamilton, Khirbat al Mafjar, pl. 78, no. 18; and Figure 1, crudely redrawn after Hamilton's plan). I find no other occurrence of such a floating motif.6 It is with this lozenge that I am concerned.

Circulation Patterns of the Bath

No circulation pattern that can be derived from the location of the bath's doors and features of its elevation leads to or through the lozenge. From the private entry the owner could have entered the pool immediately, reached the central western apse with a few steps, or proceeded to the audience hall in a straight line. From the public entry, facing the central western apse, guests could have headed to the right to the latrine (entered through a door east of the easternmost apse on the north side) or the hot rooms (entered through the western apse on the north side); or they could have headed to the left to the pool; they would have disrobed in the main hall, leaving their clothes in any of the niches that lined it, or on the wooden benches installed in most of the apses.7 Guests coming to meet the owner could have proceeded due west to the central western apse or by some undefined route to the audience hall. There is no door in the central apse on the north side, so there was no completely axial approach to the pool.

There are other clues to the circulation pattern in the pavement. The continuous carpeting of the three aisles strongly suggests they were intended to be walked along. The two exceptions to the scheme outlined above by which the pavement was divided into fields are panels 15 and 25. Panel 15 lies just north of the pool, covering what would otherwise be three fields: this feature seems to be a matter of formal correspondence to the pool8 or (more likely, I think) to the three full aisles.

More importantly, panel 25 lies west of the public entry, just beyond panel 1, which covers the eastern aisle. Panel 25 covers what would otherwise be two fields: the space between the two central eastern piers and the next bay to the west, on axis with the central circle and the central western apse. The double size of this panel defines what may be thought of as an entry zone: a guest entering from the west who did not turn immediately left or right along the eastern aisle instead stepped forward onto panel 25. Having done so, he would then have three choices: continue west on axis, or turn left to the pool or right, perhaps to traverse the northern bays of the nine-bay zone to reach the hot rooms or the audience hall (there may have been some water feature in the westernmost apse on the north side, where the entry to the hot rooms was, which would have made the northern aisle unsuited as a route for clothed guests headed to the audience hall).9

Such routes—or others—could have been defined by curtains stretched between the piers. The Umayyads often seated themselves behind curtains before receiving guests.10 Hamilton thought there could have been curtains around the pool and in front of the apse of the audience hall.11 I can imagine a curtain hung between the piers at the west edge of panel 25, blocking a direct view of the western apse and directing guests to one side or the other. But this curtain is pure speculation on my part; because of the destruction of most of the height of the piers there is no direct evidence for it.

Variations of complexity in the design of the panels of the mosaic pavement provide further evidence for the circulation pattern. Hamilton categorized them in seven groups on formal grounds, and it so happens that these groups are nearly uniformly of different degrees of complexity.12 Working from outside in and north to south, I arrive at the following observations:

To summarize, there is a clear and systematic distribution of the more complex patterns in the three long aisles, along the central east-west axis leading to and including the central western apse, and in front of the pool, including the panel between piers closest to the private entry (for which I have no explanation),15 and in the apse on the other side of the hall, the design of which indicates that it either had some significance (which escapes me) or was originally planned to.

Significance of the Lozenge

Still, none of these observations on circulation patterns yields a direct route to the lozenge. To reach the lozenge a guest would have to have wandered around to it or have been directed to it by attendants or some means such as an arrangement of curtains. Standing at the lozenge, the guest would have faced not the central western apse but the center of the pool. So the lozenge may be connected not with circulation but with static location: it may be a place-marker. But for what purpose?

Hamilton interpreted the bath variously and in combination as a “ceremonial apartment with provision, and extravagant provision, for bathing parties” or “Frivolity Hall”; as a majlis al-lahu or “play-room … designed with the spatial, acoustic and decorative properties requisite for the entertainment of a numerous company with music, bathing, perhaps ball games and … other relaxing pastimes”; and as a “music room”.

The main hall was not a ceremonial apartment: the ceremonial apartment—if that is what it was—is the separate, finely decorated chamber entered from the northwest corner of the main hall. The central western apse, as it has been interpreted, is a travesty of a formal throne setting. Nor is the plan of the main hall suitable for an audience hall with the central western apse as its focus, as the piers block the view of that apse from much of the hall. Known Umayyad audience halls at Khirbat al-Minya and Mushattâ are instead basilical.

Then again, the main hall may have been intended to accomodate functions such as were associated in Antiquity with large unheated rooms in major baths, including athletic competitions such as wrestling; or performances by the acrobats and dancers who may appear in the frescoes of Qusayr `Amra.16 But an audience for such performances would have found its view obstructed by the piers, and the performers would have had to work around them. As for Hamilton's suggestion of ball games, it would be a strange ball game indeed that could be played among so many obstacles.

In Roman baths the large unheated hall was usually a single unobstructed space, as known in Rome from the Baths of Titus, Caracalla, and Constantine, and reflected in the European and North African provinces.17 The Baths of Diocletian in Rome offer only a partial exception, but even there the subsidary spaces screened by columns were dwarfed by the vast central space. Among Umayyad baths, both Qusayr `Amra and Hammâm al-Sarakh have unheated halls of three aisles opened by large arches to form as unified a space as possible using the architectural devices the builders seem to have had at hand. At `Anjar there is a bath at the north city gate with a main hall of three aisles on four piers, but these are slim compared with the massive piers at Khirbat al-Mafjar, and again the intent must have been to create a relatively unobstructed space.18 Thus there is no parallel in bath architecture for an unheated hall filled with piers.

It may be, of course, that the Umayyad builders of Khirbat al-Mafjar simply could not vault so large a space in stone and brick, and that the form of the main hall is an unhappy compromise sacrificing sight lines and open space for overall size. But Hamilton's last suggestion, that the main hall was intended for musical performances (including recital of poetry), is of a function that required no line of sight between performers and most of the audience. Based on anecdotes of the life of the Umayyad caliph al-Walîd II, whom Hamilton believed (with reason but not beyond dispute) to have built it, he emphasized what he felt was the acoustic suitability for singing of the many curved surfaces of the elevation.19

Music and oral recitation were activities also performed in churches. Consequently churches may be considered as possible prototypes, especially as Hamilton notes that al-Walîd spent much time—drinking—in monasteries, although none of the anecdotes he collected mentions any performance in a church.20 The central nine bays of the main hall, plausibly reconstructed by Hamilton with a central dome on a drum (to which I add four corner domes), recall cross-in-square churches. But this is a deceptive similarity. Cross-in-square churches are not ringed with aisles and apses on all sides. The main hall would not have impressed a visitor as being like the sixth-century Ghassânid building north of the city walls of Rusafah, which has a nine-bay plan and has recently been reinterpreted as a church.21 Syrian churches of centralized plan, such as the cathedral of Busrâ, could perhaps be more likely as inspiration for a design full of curved surfaces, but they have large central spaces.

It is possible to conclude that the main hall would not have been unsuited to musical and poetic performances because of its hypostyle interior, and if the curved surfaces of its elevation—and the breaking up of space with the many piers—in fact enhanced sound, or at least were expected to do so, it would have been positively suited to auditory performance.22 In short, despite the lack of clear formal prototypes, the peculiar form of the main hall of the bath suits it better to musical and poetic performance than to anything else.

The lozenge points to the disposition of performer and at least the principal member of the audience. Hamilton seems to have thought that al-Walîd usually occupied the central western apse or the audience hall, but there is no reason this must have been so. The middle of the pool on the south side would have been just as good a listening point as the central western apse for any performance occurring under the central dome, and several of the anecdotes about al-Walîd and singers place al-Walîd in a pool. Hamilton thought that a reciter or singer would have stood or sat on the central circle, which he labelled “the performer's circle.” 23 So the lozenge may have been intended to signal a place to stop before approaching the pool or stepping into the central circle (if it marked the threshold of the central circle). We can imagine a performer approaching the pool from the north, guided by attendants, arriving at the lozenge, and standing under the central dome facing the pool, not the central western apse, to perform.

Alternately, the lozenge may instead have represented an important place to stand or sit. In a more intimate arrangement, the performer would have stood or sat in the central circle and the patron on the lozenge. Or, as the design of the central circle corresponds to the central western apse, which is one of the special locations presumably reserved for the owner on some (other) occasions, the performer would have stood or sat in the lozenge and the patron in the central circle, marked as his special spot, at the point where echoes of the music converged and in the center of the most magnificent element of the mosaic floor.

Other Lozenges in Umayyad Pavements

In a partial survey of floors in other Umayyad palaces I found few other lozenges, and none on thresholds. At Qusayr `Amra a lozenge similarly developed with knots and with a circle in its center is set in the back of the mosaic pavement of the apse of one of the two small rooms behind the three-aisled hall.24 This paucity of threshold mosaics and place-markers may show that the meanings borne by the mosaic pavement of Khirbat al-Mafjar were drawn from Late Antique practice in a particularly idiosyncratic and conscious way that was not paralleled in other Umayyad palaces. If not, the lozenge north of the central circle in the Khirbat al-Mafjar bath pavement may represent a tradition of using place-markers that has gone unnoticed in early Islamic architecture.

Geddes, Cairo, 1965, pp. 105–31, figs. 3 and 5. (Kessler also noted some aspects of the distribution of mosaic patterns at Khirbat al-Mafjar but with attention to the interlace ornament. The design in the other small room corresponding to the lozenge is a vase with vine tendrils emerging from it; I do not see a correspondence with the lozenge, but perhaps there is one). This lozenge was also noted by Julian Raby, “In Vitro Veritas. Glass pilgrim vessels from 7th-century Jerusalem”, Bayt al-Maqdis: Jerusalem and Early Islam (Oxford Studies in Islamic Art v. 9, pt. 2), Oxford, 1999, pp. 113–90, p. 127, in another context. In that context Raby sees the lozenge enclosing a circle as a symbol (my word) for Jerusalem as the omphalos of the world (pp. 184–90). That particular symbolism cannot apply to Qusayr `Amra and Khirbat al-Mafjar; how the omphalos-symbolism of the lozenge and its use as a place-marker are connected is a fascinating topic I cannot explore here.
