  • Fig. 9 - Re-used Building elements from Bedal et al (2007)

Discussion

Renovations during Phase III dated to the early 2nd century CE may have been a response to seismic damage most of which may have been cleared by renovations. The re-use of building elements (see Fig. 9) may be reflective of this response. It should be noted that these building elements could have come from another structure - for example the nearby Great Temple where Joukowsky and Basile (2001:50) report an early 2nd century CE earthquake in Phase VI.

Bedal (2003:74) estimated an early 2nd century CE terminus post quem for the start of Phase III1 based on pottery found associated with various structures that were part of the renovations.
According to the refined pottery sequence from ez-Zantur, the type 3c Nabataean painted ware was produced in a brief span of time, between ca.100 and 106/114 CE. Based on this pottery evidence, it is possible to assign the floor bedding and by direct association the bridge with a terminus post quem of the early 2nd century CE.

... However, a single rim sherd also found embedded in the floor mortar (Fig. 18) may be more closely identified with a type 4 painted bowl from ez-Zantur, dated post-106/114 CE (Schmid 1996:166, 208, abb. 704), in which case the Phase II renovations in the Pool-Complex must be dated to a period following the annexation of Petra into the Roman Empire.

Discussion

Bedal et al (2007) report seismic destruction in Phase V as follows:
The architectural elements of the pool complex suffered serious damage in the mid-4th century AD, most likely a result of the well-documented earthquake of 363 AD. The upper courses of the pavilion walls collapsed into the pool, forming a dense layer of large stone rubble in a reddish-brown sandy matrix overlying the Phase IV fill (trench 1) (Fig. 24). In the south-west corner, stones falling from the South Wall and the Great Temple's East Perimeter Wall formed a similar destruction layer (Fig. 23).
Bedal (2003:79) entertained the less likely possibility that the observed destruction was due to decay rather than seismic forces.
While it is possible that this destruction resulted from neglect and structural decay over a long period of time, it more likely that the island-pavilion fell victim to the major earthquake of 363 CE that caused irreparable damage to many of the major monuments at Petra and destruction throughout the region (Russell 1980; 1985:42; Amiran et al. 1994:265). 74
Footnotes

74 The much-debated earthquake at the beginning of the 2nd century CE (Schmidt 1997) can be ruled out here because of the late (4th century CE) pottery underlying the destruction debris.

Bedal (2003:79) dated Phase V1 seismic destruction to the 4th century CE unlike Bedal et al (2007) who dated it to the mid 4th century CE.

  • Fig. 5 - Earthquake collapse at Pool south-west from Bedal et al (2011)

Discussion

The 2009 excavation in pool south-west, supervised by James G. Schryver, consisted of a baulk of overburden composed of alternating strata of earth / rubble wash, earthquake collapse and post-Classical walls apparently constructed to retain the accumulated soil and control water runoff from az-Zanṭūr. The defined area (8 x 9 x 4.5 m) is immediately north of Trench 12 (2004) and runs up against the east face of the Great Temple east perimeter wall (GTEP wall). Careful delineation of the stone fall and constructed walls helped to distinguish the strata of rubble debris from two major earthquake collapses and the construction of a late (post-Classical) wall to support the earth - rubble wash that was coming down from az-Zanṭūr and filling the pool area. The wall revealed itself to be built of two faces of large recycled ashlar stones surrounding a core of rubble stones. The southern ashlar face of the upper portion of this wall had collapsed, revealing a packing of smaller stones (Fig. 5). Further excavation in this area will be necessary to fully understand just how deep into the fill of the pool this wall extends, thereby determining its date and stratigraphic relationship with the earlier architecture.

Evidence for this wall serving as a check dam or terrace wall that was a part of a larger system of soil retention across this part of the site came from our soil specialist, John E. Foss, who noted that the fills against the wall were waterlain and that certain surfaces within the fill may have been cultivated. The east - west wall of the check dam was further integrated with a wall running north - south along the western edge of the pool, directly above the pool’s west perimeter, apparently to direct and divert water along the western edge of the pool area down to the garden terrace which functioned as an agricultural field in later periods. The construction of this wall may be associated with the collapse of the GTEP wall and the resulting redistribution of soils during the winter foods. The proposed cultivation of these soils seems to have been contemporary with a second collapse, as most of the stones from this collapse seem to have been collected and then thrown up against the base of the northern face of check dam in the form of a convex buttress. A later collapse must have occurred once the area was no longer being cultivated as those stones were left in place, spread across the ground surface. These activities are all attributed to PGPC Phases V - VIII (Late Roman - Post-Classical / Medieval).

Discussion

Another area that required attention during the 2007 and 2009 field seasons was the western boundary of the pool area that adjoins the Great Temple upper temenos (Fig. 6). The west face of the GTEP wall was uncovered by the Brown University excavations, along with two of the intermural rooms (Room C and the small reservoir)5. However, the continuation of the wall to the north of the small reservoir remained unexcavated.

Trenches 20 and 21 were opened to define the eastern face of the northern extension of the GTEP wall (the southern portion was exposed in 2004, Trench 12) and to begin excavating the intermural spaces. Trench 20 defines a single intermural room immediately to the north of the small reservoir. Work here revealed the upper courses of a baked brick construction that lines the interior walls (dimensions 7.25 x 2.20 m). The walls are single brick width (36 cm) on all sides, with steps measuring a single brick width which measure 36 x 36 x 6 - 8 cm, are poorly fried with heavy chaff and are cemented with a crumbly grey mortar tempered with small pottery fragments (primarily Nabataean fine ware). Diagnostics include Nabataean painted pottery dating to the second century AD providing a terminus ante quem for the construction of this installation in the second quarter of the second century AD. The brick construction is similar to some of the construction in the bath complex west of the Great Temple that has been assigned to the Roman - Byzantine period (Joukowsky 2007: 154-8). It can thus be deduced that the brick feature represents a secondary use of the intermural space within the GTEP Wall dating to the second or third century AD at the earliest. The heavy use of mortar and plaster, in addition to the presence of steps in one corner, suggests its function as a water basin or pool. The center of the basin is badly damaged by a large pit, filled with large stones in a greyish - brown ashy matrix. The trench was closed and sandbagged to protect the poorly preserved bricks pending future study.

Trench 21, located immediately north of Trench 20, measures 3.50 x 11.25 m. Its dimensions are defined by the width of the casemate wall and the length of the space north of Trench 20 to the north face of the pool and the Great Temple east exedra. Excavations began in 2007, defining the line of the east wall and clearing the topsoil and fill and that was heaped up against the west wall. In 2009, excavations continued under the supervision of William A. Caccese and Leigh-Ann Bedal with removal of sandy rubble fill, earthquake collapse and small dividing walls of later date (post-Classical / Medieval) that revealed the remnants of the original Nabataean structure. At the north end, a doorway between the Great Temple’s east exedra and the pool leads to a well-preserved staircase constructed of sandstone paving slabs (Figs. 8a and b). This staircase provided access from the garden terrace to the pool level. At the top of the stairs is a landing leading to a broad (2 m wide) doorway and a room (foyer) with doors opening to the east - leading to the pool’s west promenade - and to the south - leading to the room in Trench 20 described above.

During the Byzantine period, a wall was built up between the Great Temple’s east colonnade and the pool wall)6, forming an oblique passageway from the colonnade into the staircase (Fig. 8b, far left). It is probably at this time that the doorway between the staircase and the foyer was frst narrowed. Subsequent to the construction of the Early Byzantine wall, a greenish - grey clayey deposit, containing a high density of animal bones and pottery sherds, accumulated on the landing, staircase and the floor of the Great Temple’s east exedra. Joukowsky notes that this thick grey deposition may be indicative of the use of the closed exedra area as a lime kiln (Joukowsky 2007: 110, Fig. 3.33), however, the nature of the deposit covering only the east half of the top steps and then spreading out across the bottom of the stairs (Fig. 8b) and the exedra floor, suggests that the material originated from the pool - perhaps an effort to clean rubbish and stagnant water accumulated in the now unmaintained pool - and was thrown (or poured) down to fill the staircase and the exedra. Later the foyer doorway was completely blocked and the staircase landing and foyer spaces partitioned with narrow dividing walls constructed of re-used stones, possibly representing a squatter settlement that likely coincides with the Late Roman - Byzantine squatter settlement (PGPC Phase VI, forth-fifth centuries AD). Above this lies a deep accumulation of collapsed debris consisting of stone rubble and large architectural blocks in a sandy matrix (PGPC Phase VII) (Bedal et al. 2007: 166).

With approximately half a meter of fill remaining above floor level, Trench 21 was not completed by the end of the 2009 field season. A study of its full stratigraphy and material contents will commence on its completion in the next field season (planned for 2011) and should provide valuable information about the chronological sequence of construction, re-use, fill and earthquake collapse.

Discussion

Bedal et al (2007) report seismic destruction in Phase VII as follows:
A stratum of large stone debris in a reddish-brown sandy matrix overlying the Phase VI fill in the southern half of the site (trench 1, 3, 4 5, 9, 11, 12, and 14) marks a second major destruction episode causing the further collapse of the walls surrounding the pool complex and the island-pavilion (Fig. 24). Elements of the pavilion's architectural decor (marble flower, volutes, capital fragments and painted stucco) and its construction (iron nails, a plaster nail anchor, and charred wood) mark further disintegration of this structure.
Bedal (2003:83) discussed this potential seismic destruction in a similar manner in a passage which is less certain that the debris from this phase was a result of seismic destruction.
It is clear from the presence of architectural debris in this stratum - large architectural elements (ashlars, doorjambs, etc.), small capital fragments, volutes (Pl. XVIIIa), and a unique flower (carved from limestone or a low-grade marble) (Fig. 12 and Pl. XVIIIb), iron nails, a plaster nail anchor, and some charred wood - that the structure continued to disintegrate following its major destruction as a result of the 363 earthquake. At this time, there is no evidence to specifically link this secondary collapse with the 551 earthquake, although that cannot be ruled out.
