Introduction

Mount Nebo is famous as the location where in the 34th chapter of Deuteronomy Moses climbed its peak to view the promised land before passing away. Only ~ 7km. from Madaba, it provides a commanding view of the Dead Sea, Judah, and Samaria. The ridge of Mt. Nebo has been inhabited since remote antiquity, as the dolmens, menhirs, flints, tombs, and fortresses from different epochs testify (Michelle Piccirillo in Meyers et al, 1997). Several churches and a monastery were built there in the Byzantine era.

Identification and History

Mount Nebo rises from the Transjordanian plateau 7 km (4 mi.) west of the town of Medeba (Madaba). It is bounded on the east by the Wadi 'Afrit (which extends into the Wadi el-Judeideh, the Wadi el-Keneiseh, and the Wadi el-Hery farther south) and on the north by the Wadi Abu en-Naml, which extends into the Wadi 'Uyun Musa to the west. Mount Nebo's highest crest reaches an altitude of 800 m above sea level. The other peaks are slightly lower. Of these, the two most historically important are the western peak of Siyagha and the southern peak of el-Mukhayyat. Nebo provides a unique natural balcony fora spectacular view of the Jordan Valley and the mountains of Judea and Samaria. The ridge of Mount Nebo was inhabited in remote antiquity, as dolmens, menhirs, flints, circles, tombs, and fortresses of different epochs testify. However, its real fame is derived from the events described in the Book of Deuteronomy 34:1-7: the final vision and death of Moses.

The Bible also associates the following events with Mount Nebo or its immediate vicinity: the passage and camp of the Israelites (Num. 21:20 ff., 33:47 ff.); the story of Balak and Balaam (Num. 23:13-26); and the concealment of the tabernacle, the ark, and the altar of incense in a cave (2 Mace. 2:4-8). From these geographical texts, it is known that Mount Nebo, part of the Abarim mountain range, was located east of the Jordan River, opposite Jericho. It was also known as Pisgah:
And Moses went up from the plains of Moab to Mount Nebo, to the top of Pisgah, which is opposite Jericho. And the Lord showed him all the land .... So Moses the servant of the Lord died there in the land of Moab, according to the word of the Lord, and he was buried in the valley in the land of Moab opposite Beth-Peor, but no man knows the place of his burial to this day (Dt. 34: 1-7)
In the Bible, as in the stela of Mesha, king of Moab, Nebo is listed among the cities in the land of Moab, in the territory of Medeba (Num. 32:3, 32:38; 33:47; 1 Chr. 5:8; Is. 15:2; Jer. 48:1, 48:22; 1 Mace. 9:37). King Mesha conquered the town, killed the inhabitants, and "took from thence the vessels of Yahweh and dragged them before Chemosh" (lines 14-18). Mount Nebo, as a sanctuary dedicated to Moses, was known by scholars and visited by Byzantine pilgrims. In the fourth century CE, Eusebius, in the Onomasticon, wrote:
Nabau, which in Hebrew is called Nebo, is a mountain beyond the Jordan, in front of Jericho in the land of Moab, where Moses died. Until this day it is indicated at the sixth milestone of the city o fEsbous [which lies to the east.
The Roman pilgrim Egeria (late fourth century CE) and the bishop of Maiumas in Gaza, Peter the Iberian (fifth century CE), relate in great detail their visits to the Memorial Church of Moses on Mount Nebo in Arabia. Egeria, after having crossed the Jordan on her way from Jerusalem, had stayed at Livias and then took the road to Esbous. At the sixth mile, she took a turn to the Springs of Moses and from there climbed to the summit of Mount Nebo. The bishop took the same road in search of a cure for his afflictions. After bathing in the hot Springs of Moses, with little benefit because the springs were not very hot, the party continued on its way to the hot springs of Baaru, where the waters were much hotter and more curative. The journey offered Bishop Peter and his companion the opportunity to stop at the sanctuary of Moses, where he had visited as a youth, before his conversion to Christianity (Life 82-85).

The pilgrim Theodosius (early sixth century) relates that not far from the city of Livias, east of the Jordan River, pilgrims could visit "the water made to flow from the rock, the place of Moses' death, and the hot springs of Moses where lepers come to be cured." The pilgrim of Piacenza (late sixth century) adds: "From the Jordan to the place where Moses died, it is eight miles." The survival of the name of Nebo in the region was discovered in 1838 by E. Robinson and E. Smith. It was only in 1864 that the French explorer Le Due de Luynes visited and described the important ruins covering the spur of Siyagha 9 km (5.5 mi.) west ofMedeba, overlooking the Jordan Valley. As a result of diligent research among the Bedouins in the area, it became known that the mountain was also called Jebel Nebo and Jebel Musa because of its proximity to Wadi 'Uyun Musa, on the northern slope of the mountain. The discovery in Arezzo (Italy) of Egeria's memoirs, published by F. Gamurrini of the University of Rome in 1886, and the subsequent discovery of the Syriac biography of Peter the Iberian in 1895, were decisive in the historical identification of the Memorial of Moses visited by pilgrims with the ruins on Siyagha, the western spur of the mountain. Archaeological survey and excavations have shown that an Iron Age fortress was located on the southern spur of el-Mukhayyat, and that the site was inhabited almost continuously until the Umayyad period. This justifies the historical identification proposed by scholars of the town of Nebo with the ruins of el-Mukhayyat.

Exploration

H. B. Tristram, in 1872, was the first to visit the ruins of el-Mukhayyat, although the name had already been recorded in 1863 by F. de Saulcy. Members of the American Palestine Exploration Society visited Mount Nebo in 1873, led by E. Z. Steever, and in 1875, led by S. Merrill. In 1881, Mount Nebo was surveyed by the British Palestine Exploration Fund, under the direction of C. R. Conder. The flora and fauna of the mountain were studied in 1886 by G. E. Post. In 1891, G. Schumacher attempted to identify the ruined buildings on Siyagha. In 1901, A. Musil paid a number of visits to Siyagha and surveyed the ruins at el-Mukhayyat. He was the first to propose the identification of the place with the town ofNebo. The Dominican Fathers P. Janssen and R. Savignac visited the ruins of el-Mukhayyatin in 1907. There, in 1913, the mosaic floor of the Church of Saints and Martyrs Lot and Procopius was identified. It was published in 1914 by F. M. Abel. N. Glueck visited el-Mukhayyat in 1934.

The decision of S. J. Saller of the Studium Biblicum Franciscanum to excavate the ruins of the Memorial of Moses prompted the superiors of the Custody of the Holy Land to purchase the spurs of Siyagha and elMukhayyat. In 1933, the Franciscan archaeologists began their exploration of the site. Three long campaigns at Siyagha-directed by Saller in 1933, 1935, and 1937-resulted in the discovery of the basilica and of a large monastery that had developed around the sanctuary in the Byzantine period. Three churches were also excavated at Khirbet el-Mukhayyat. In 1962, J. Ripamonti of the University of Caracas undertook a systematic study of the necropolis at el-Mukhayyat and excavated a small monastery (el-Keneiseh) and an Iron Age tower east ofthe ruins. Pottery found in the tombs and subsequently studied by Saller furnished excellent points of reference for developing a chronological sequence of habitation at the Mukhayyat Monastery on Siyagha hill: fragments of a Samaritan inscription. site. In 1963, the modern restoration of the Memorial of Moses was assigned to V. Corbo, who began with the mosaic floors inside the basilica. In 1976, the project was assigned to M. Piccirillo, who was later joined by E. Alliata. Work continues on the restoration of the main historic monument and one the exploration of the mountain's other antiquities.

Phase Date Notes
I 2nd-3rd cent. CE On the highest spot of the mountain, towards the 2nd to 3rd century AD, a three-apsidal monument, the cella trichora (possibly a mausoleum) was built, which was used for funeral purposes, if not originally, at least at a later time, perhaps after its violent destruction.
II Christian monks re-adapted the cella trichora into a church with adjoining synthronon in the central apse, while re-using the two lateral apses as sacristies.
It was in this church that the monks showed the `Memorial of Moses' to Egeria.
IIA On the northern slope of the mountain was added later on a diaconicon-baptistry. In August 531 there took place the restoration and beautification of the diaconicon, the mosaic floor of which was laid by Soelos, Kaiomos and Elias.
III From the middle of the 6th century to the first years of the 7th, the sanctuary underwent complete reconstruction.

Discussion

Bianchi (2019:210) reports that during the last architectonical phase of the Memorial to Moses basilica on Mount Nebo, "the two upper rows of synthronon and the masonry of the apse in the presbytery were restored".

Bianchi (2019:210) suggests that "the large amount of pottery and marbles with sharp fractures recovered in the excavation, as well as the disorderly arrangement of stones in the external apse buttress suggest that a brutal destruction occurred in the site" which they indicate is "related probably to the earthquake of 749 AD".

Conversely, Bianchi (2019:210) notes that "the morphology of this structure may have been affected by the geological instability of the northern slope".

In any case, Bianchi (2019:210) states that "the second half of the eighth century well agrees with the chronology of the pottery recovered beneath the upper rows of synthronon" where "most of the sherds date indeed to the late Umayyad period" and a "few to the Abbasid era".

Introduction

The Memorial of Moses on Mount Nebo, in the Roman province of Arabia, in the territory of modern Jordan, is a classical example of a monastic complex related to the shrine of a biblical figure. In this site the devotees used to worship the memory of the place in which, according to Biblical tradition, the "Prophet Moses" died after having seen the Promised Land (Sir. 45:1). The word Ṣiyāgha, used to call the western spur of Mount Nebo, means in Aramaic "monastery, community of monks" (Saller 1941: 115-117). This name is indeed related the ruins of a large Byzantine monastery (almost 6640 sq.) established in the fifth century AD. and articulated in several rooms surrounding the central basilica (FIG. 1). In addition to the main coenobium , a colony of ascetic monks have dwelled in the caves of the mountain located in the surrounding valleys (Hamarneh 2014). Although most of these hermitages were beyond the boundary of the monastery, the abbot of Ṣiyāgha had jurisdiction over them (Hamarneh 2012: 279). The life of the monastic community continued also during the Islamic rule, most probably up to the end of the ninth century.

After having acquired the site thanks to the concern of the Emir Abdallah Ibn al-Husayn I, the Custody of the Holy Land began the first archaeological expeditions on July 14/ 1933 under the direction of Fr. Sylvester Saller (Saller 1941: 17). The excavations then continued with Fr. Virgilio Corbo (1963), Fr. Michele Piccirillo (1976) and Carmelo Pappalardo (2008)1 . Since 2012, the Studium Biblicum Franciscanum, under the direction of Fr. Eugenio Alliata assisted by the author, have conducted some archaeological investigations in connection with the re-roofing of the ruins of the church. The geological instability of the mountain led indeed to replace the old shelter with a new one (Marino 2004: 47-64).

The aim of this article is to provide a general presentation of the excavations conducted between 2012 and 2014, with a focus on the most important discoveries and their interpretation. Due to the limited space given for this paper, the analytic study of the archaeological record will be published in a forthcoming monograph of the author (Bianchi dissertation forthcoming).

Interpretation of the Excavation

The Construction of the First Basilica

The analysis of the last archaeological data and the review of the previous interpretations support a new hypothesis about the oldest worship building arose on Mount Nebo. The first crucial issue is related to the understanding of the space in front of the tri-conch Presbytery. According to Saller’s suggestions, this cell was the oldest shrine erected on the site and the area in front of it was an open courtyard with a mosaic floor (Saller 1941: 23–44). However, the excavation conducted by Corbo and later by Piccirillo and Alliata have determined that some walls of the church were built before the thricora cell (Alliata and Bianchi 1998: 151–154). In addition, the shape of the area in front of the cell, surrounded by regular masonry and paved with mosaics, seemed not to characterize an outdoor courtyard.

Considering all the architectural evidence, it is thus possible to assume that the first church probably showed a rectangular basilical plane divided into three naves by two series of pillars (FIG. 10). Many parallels in Transjordan support this hypothesis (Michel 2001: 18–33). The perimetral masonries related to this phase are located on the northern and western sides of the church, under the walls of the main nave which are visible today. The north wall is thus connected perpendicularly to the eastern wall and continues on the south side with the façade characterized by three doors. As aforementioned, the small portions of the mosaic floor found in the nave do not indicate epigraphically when they were laid. However, the pottery sherds and coins recovered in the preparatory layer of this mosaic provide a terminus post quem between 408 and 423 AD which suggest that the mosaic floor, and so the first church, could be dated to the second half of the fifth century AD.

The excavation of the three rooms behind the east wall of the church allowed to recover many pottery sherds of the early Byzantine period and one coin dated back between 383 and 425 AD. This data suggest that this sector was built after the second half of the fifth century AD, most probably at the time of the first architectonical phase of the basilica. The three tombs located in the central room were covered with a white mosaic floor, which is of the same type and at the level to those found by Saller and Corbo in the northern and southern rooms (Alliata – Bianchi 1998: 187, nn. 43,50,51; Saller 1941: 50; Corbo 1970: 278). It is noteworthy to mention that the quality of the mosaic of the southern room, decorated with a cross in black and white cubes, well agrees with this archaeological record (Piccirillo 1998: 268). The central room would probably be covered with an arched roof: two blocks of the arches foundations have been identified in the excavation.

Similarly, the empty tomb was probably built in this first phase because it was found sealed by the preparatory layer of the nave mosaic. In addition, looking at the topography of this burial place, it is possible to observe how the tomb is located on the higher portion of bedrock compared to the level of the nave floor. Moreover, the grave is surrounded with a shallow cut, which suggest the presence of a frontal step and two lateral walls in antiquity. According to the architectural typology of the “ sanctuaire carré4, it is possible to assume that square portion of the bedroom with tomb was actually under the presbytery of the oldest church provided with two lateral pastophoria.

Another key element in support of this hypothesis is given by the written sources. A reference in the *Life of Peter the Iberian*, wrote by John Rufus, recalls the presence of a special altar above the grave in the memory of the “Prophet Moses” (Peter the Iberian 2008: 177–179).

The origin of the alabaster marbles, reused in the tomb, remains an open question at this state of research. The three angular bases with fine moulding, thin slabs and three fragments of frame were probably part of the external or interior façade of a small building. If we assume a specific production related to the first memorial on Mount Nebo, the marbles might have adorned the oldest cenotaph built in the memory of Moses. In connection with this hypothesis, it is crucial to mention the description of the pulpit saw by Egeria, who visited Nebo around 384 AD.
We arrived, then, at the summit of the mountain, where there is now a church of no great size, on the very top of mount Nebo. Inside the church, in the place where the pulpit is, I saw a little raised place, containing about as much space as tombs usually contain 5.
According to the textual source, the sentence a church of no great size (*ecclesia non grandis*) may properly suggest a modest building. Concerning to the location of the burial of the Prophet, the monks showed to Egeria a generic point inside the church, without providing more detailed information (*Itinerarium Egeriae*, XII, 3). Unfortunately, at this stage of the study, no stratigraphic evidence dates back to the time of Egeria. The oldest structures discovered in the site were indeed built not prior to 408/423 AD, with a gap of more than thirty years after Egeria’s visit. However, the topography of the squared area around the empty tomb might suggest that the *pulpitus* described by the pilgrim was located in this place.

It is worth to stress that no violation has occurred previously in the grave. Although the absence of human bones could suggest a later removal, the shallow type of the tomb with no traces of liquid decomposition or soil, contrast with this hypothesis. This evidence may support the identification of the tomb as a cenotaph, probably built by Christian monks. Therefore, through the creation of this memory, the Christian devotees could go on a pilgrimage to a specific site related to the worship of the prophet Moses but without any tangible remains. In addition, the detailed description of John Rufus, who mentions the oral tradition related to a vision of the prophet by a local shepherd, adds a bold rhetorical exercise to support the precise identification of the worshipped tomb (Bitton-Ashkelony and Kofsky 2006: 64–65; Satran 1995: 97–105). This evidence confirm that the cenotaph on Mount Nebo was a Christian prerogative since both the Torah and the rabbinic tradition considered unknown the burial place of Moses (Bitton-Ashkelony and Kofsky 2006: 62–81; Tromp 1993: 115–123; Manns 1998: 65–69).

In this perspective, the monastic shrine of the memorial of Moses is part of a network of Jordanian coenobia associated with the worship of the biblical figure 6 (Hamarneh 2012: 277-279).

The Phase of Partial Reconstruction with the Addition of the Tri-Conch

During the second architectonical phase phase the church underwent a radical transformation (FIG. 11). Firstly, a new mosaic floor in the nave replaced the previous one, probably because of the replacement of pillars with columns resting on independent foundations. The mosaic portions and the sherds of pottery recovered at the base of the columns confirm clearly this hypothesis.

Furthermore, the cenotaph was completely obliterated; the three rooms behind the chancel were demolished to lengthen the three aisles at the end of which a new tri-apsidal presbytery was added. The slight divergence of the tri-conch presbytery with the masonry of the three apses, which rely upon the foundations of the nave, suggest indeed a later construction. The choice to build a tri-conch presbytery is related probably with the funerary function of this architecture, as the parallels with the Egyptian churches may suggest (Grossmann 1999: 216-236; Grossman 2007: 103-136).

The pottery and coins recovered in the excavation of the presbytery date its construction to the end of the fifth or the beginning of the sixth century AD, probably at the time of abbot Elijah and the bishop Elijah of Madaba. The mosaic floor, which seals the two graves located under the presbytery and leans on the first row of the synthronon, confirms this chronological range. Moreover, according to Piccirillo the iconography of this mosaic demonstrate that it was laid before the flowering of the Justinian mosaic school of Madaba. (Piccirillo 1998: 270-272; Piccirillo 2000: 139-190).

Finally, a new diakonikon with a baptismal font was erected on the northern side of the aisle, one-meter lower than the nave (Alliata and Bianchi 1998: 168-171). The floor was covered with an exquisite mosaic, which was funded in 530 AD by three σχολαστικοί (lawyers), members of important families of the imperial administration (Piccirillo 1998: 273-287).

The Phase of Reconstruction of the Basilica

Introduction

A new reconstruction of the entire basilica occurred during the third architectonical phase (FIG. 12). The external walls of the church were rebuilt, a new mosaic floor replaced the previous one in the diakonikon and the joint financial patronage of bishop Sergius of Madaba and abbot Martyrios allowed the construction of a new chapel with a baptismal font on the southern side of the basilica (597-598 AD) (Alliata and Bianchi 1998: 176-177).

Chronologically, these architectural activities are dated back to late sixth century AD due to the mosaic Greek inscriptions and to the pottery sherds recovered under the preparation layer of the pavement (Piccirillo 1998: 296-300).

At the same time, the external wall of presbytery were rebuilt. The heterogeneity of the stone row of the apse and the archaeological records from the deep foundation cut show that a complete reconstruction occurred indeed at the end of the sixth century7.

Finally, in the first decade of the seventh century, the bishop Leontius of Madaba and abbots Martyrios and Theodoros promoted the construction of a new chapel on the southern side of the church for the worship of the Virgin Mary (Theotokos) (Alliata and Bianchi 1998: 178-179; Piccirillo 300-304).

The Umayyad Phase

During the last architectonical phase, the two upper rows of synthronon and the masonry of the apse in the presbytery were restored (FIG. 13).

The large amount of pottery and marbles with sharp fractures recovered in the excavation, as well as the disorderly arrangement of stones in the external apse buttress suggest that a brutal destruction occurred in the site. This catastrophic event is related probably to the earthquake of 749 AD. (Tsafrir 2014: 111–120) and this date might be the terminus post quem for the reconstruction of the apse.

In fact, the morphology of this structure may have been affected by the geological instability of the northern slope. The second half of the eighth century well agrees with the chronology of the pottery recovered beneath the upper rows of synthronon. Most of the sherds date indeed to the late Umayyad period, few to the Abbasid era.


At the same time the two lateral doors of the façade have been closed.

Conclusion

In summary, the last excavation have provided new elements related to the architectonical evolution of the basilica of the Memorial of Moses on Mount Nebo.

A crucial discovery was the identification of the Christian shrine that can be probably identified with that of the ”Prophet Moses“. This evidence allows to include the coenobium of Mount Nebo within the network of the monasteries related to the worship of the biblical figures.

Moreover, the review of the old data, and the analysis of the new archaeological record suggest new hypotheses on the oldest building erected on the mountain.

The exponential growth of the pilgrimage during the Byzantine period contributed to the richness and the fame of this monastery. The donation of the devotees, the bishops and the lay people have allowed indeed the expansions and decoration of the church for almost three centuries.

The new Islamic rule does not seem to have affected the monastic privileges and the financial availability of the community. Archaeological data showed that even after a traumatic event, probably the earthquake of 749 AD, the monks were able to implement an important restoration of the basilica.

We hope that further analysis of unexcavated areas of the monastery and a deeper study of the Nebo region will allow us to get a clearer picture of the shape and functions of the sanctuary of Moses.

Chat GPT Summary of Archaeoseismic Evidence

The 2012–2014 excavations at the Memorial of Moses basilica on Mount Nebo documented four main construction phases. The final phase (Phase IV) is explicitly attributed to restoration activities undertaken after the earthquake of 749 CE. This phase involved rebuilding the northern sector of the basilica, including the portico of the atrium, the atrium’s northwest corner, and the pastophoria of the northern nave. Construction techniques during this phase were cruder than those used previously, involving poorly cut limestone blocks and the reuse of decorative fragments from collapsed structures.

The attribution of these restorations to the aftermath of the 749 CE earthquake is based on stratigraphic sequencing and ceramic material. Earlier phases, particularly Phase III, which dates to the end of the 6th century CE, exhibit no evidence of seismic damage, suggesting that the structural collapse requiring Phase IV intervention occurred later.

No direct evidence of ground shaking (e.g., tilted walls or fissures) is discussed, but the contextual attribution of damage and rebuilding efforts—particularly the partial collapse of architectural elements—makes this an example of archaeoseismic reconstruction based on stratigraphic and architectural transitions dated to the mid-8th century CE.

Chat GPT Summary of Archaeoseismic Evidence

Excavations at Mount Nebo provide strong evidence of seismic damage attributed to the 749 CE earthquake. In the Memorial of Moses basilica, archaeologists uncovered significant destruction, including collapsed structures and mosaic floors damaged by what was described as a "traumatic event, probably the earthquake of 749 AD." The floors were later repaired, and new mosaic inscriptions dated to 762 CE provide a secure terminus post quem for the restoration activities, suggesting a seismic event occurred shortly before that date.

Thus, estimated intensity is lowered to VII (7).

Notes

In his entry for the 659/660 CE Jordan Valley Quake(s), Ambraseys (2009:222) notes that

Indeed, Russell remarks that it is impossible to ascertain the effects of this and the AD 632 (634) earthquake on the Mt Nebo monastery owing to the manner in which the excavations were conducted.
Russell (1985:45) correlates archeoseismic destruction at Mount Nebo to the 551 CE Beirut Quake.
July 9, 551 CE

This earthquake also appears to have been responsible for the destruction and subsequent abandonment of the Town of Nebo ( Saller and Bagatti 1949: 217, n. 2).
Russell (1985:49) correlates archeoseismic destruction at Mount Nebo to one of the 749 CE Sabbatical Year Earthquakes.
January 748 CE

The final destruction of the basilica at Mt. Nebo also appears to correlate with this earthquake (Schneider 1950: 2-3),
Russell (1985:54) supplied the following notes.
At Mt. Nebo (Sailer 1941: 45-46) and Aereopolis (Zayadine 1971) in the region of ancient Moab, recovery after the 551 earthquake apparently did not occur until the end of the century. Related to this delayed recovery is the possibility that an influx of southeastern populations from decaying urban centers like Petra subsequent to the 551 earthquake was responsible for the intensified building during the late 6th and early 7th centuries in both Moab (Sailer 1941: 248) and the Negev (Kraemer 1958: 23. 28-29; Colt 1962: 21-22).
