Excavation results

The project's main area of excavation concerns a stone-built, multi-roomed cave compound along the first terrace of Avdat's southern slope (Figure 2) (Bucking Reference Bucking2017; Bucking & Erickson-Gini Reference Bucking and Erickson-Gini2020). Over three field seasons, a series of stone-constructed rooms articulating with the cave were stratigraphically excavated (Figure 3) and steps were taken to conserve the compound so that it could be included in the UNESCO visitor trail. The compound was initially of interest due to concentrations of red-painted figures and symbols (‘dipinti’) in two rooms (Bucking Reference Bucking2017). These included decorated crosses and a probable depiction of the warrior saint Theodore, possibly indicating a phase of habitation by Christian monks who maintained a martyr cult of Theodore (Negev Reference Negev1997: 122–52). This raises larger questions about urban monastic settlement patterns in the late antique Negev, which have mostly gone unexamined (Goldfus Reference Goldfus2003).

The project's three seasons of fieldwork yielded copious well-preserved organic materials, including substantial layers of herbivore dung and seeds overlying a Byzantine-period floor in the stone-built rooms. These layers, together with watering and feeding troughs, are indicative of livestock stabling. Such livestock may have played a role in viticulture, given that pack animals were used in this industry (e.g. Fuks et al. Reference Fuks, Avni and Bar-Oz2021: fig. 5). This hypothesis is supported by finds of grape seeds and the location of agricultural fields just downslope from the compound. It also accords with evidence of a flourishing viticulture industry in the Byzantine Negev Highlands, apparently involving the participation of monastic communities (Mayerson Reference Mayerson1985).

Context and chronology

To maximise information concerning agricultural regimes, diet, environment and chronology, the project implemented a robust sampling strategy for optimal retrieval of organic remains, directed by the project's archaeobotanist (D.F.). Three organically rich areas of the compound were targeted: (i) the south-western section of the built compound (Figure 4), and (ii) the northern and (iii) western sections near the cave entrance (Figure 5). Section samples were also taken for geoarchaeological analysis.

Priority was given to radiocarbon analysis to establish a site chronology, especially considering the sparsity of ceramics. Radiocarbon results were surprising: while a sample of straw extracted from mortar in the dipinti-intensive cave vestibule wall yielded dates within the expected Byzantine range, nine samples from the organic, dung-enriched south-western section were of Umayyad–Abbasid date, ranging from 1190–1320±30 BP/AD 650–890 (Figure 4) (Bucking & Erickson-Gini Reference Bucking and Erickson-Gini2020). Three newly obtained dates from the northern and western sections yielded Abbasid dates (Figure 5): two from a substantial organic layer in the northern section, and one in the western section, where Abbasid Mefjer/Buff Ware (Cytryn-Silverman Reference Cytryn-Silverman and Gutfeld2010) further corroborated this result (Figure 6). The emerging extended chronology enriches ongoing debate surrounding the fate of Negev Highland settlement in the Early Islamic period, especially that regarding continuities and discontinuities of site use between the Byzantine, Umayyad and Abbasid periods (e.g. Magness Reference Magness2003; Avni Reference Avni2008; Butler et al. Reference Butler2020).

Looking ahead

These results raise new questions and research directions to be pursued by the Avdat in Late Antiquity Project. How widespread was Umayyad–Abbasid period activity at Avdat and to what extent does it represent a continuation of Byzantine agricultural settlement versus a possible transition to pastoral nomadism? Throughout the literature are tantalisingly short references to previous finds of Islamic material culture elsewhere in Avdat (Shamir & Baginski Reference Shamir and Baginski2001), further justifying a planned systematic survey and additional excavation of the sector to gauge the extent of Islamic-period activity. Ongoing archaeobotanical and archaeozoological analyses will refine our understanding of local economic activity over time, particularly with regard to viticulture (Fuks et al. Reference Fuks2020, Reference Fuks, Avni and Bar-Oz2021). Geoarchaeological analyses for stratigraphic characterisation of sediments and chronological fine-tuning via additional radiocarbon dating (Butler et al. Reference Butler2020)—including of post-Abbasid strata—are expected to provide high-resolution documentation of Avdat's urban and post-urban phases. These combined analyses will help to identify the various groups active at the site during and after the Byzantine–Early Islamic transition.
