Introduction
ChatGPT Introduction

Gadara was one of the principal cities of the Decapolis, a group of Greco-Roman urban centers in the southern Levant. It is situated adjacent to the modern town of Umm Qeis in northern Jordan, near the Yarmouk River and the borders with Syria and Israel. The site occupies a strategic hilltop with sweeping views over the Sea of Galilee, the Golan Heights, and the Hauran.

Ancient Gadara is also associated with a well-known episode in the Synoptic Gospels—the Exorcism of the Gerasene demoniac—though the exact location of this New Testament event remains debated between Gadara, Gerasa (Jerash), and Gergesa.

The city flourished during the Hellenistic, Roman, and Byzantine periods and was known for its philosophers, poets, and intellectuals, including the Cynic philosopher Menippus. Its urban layout includes a long colonnaded street, multiple theaters, a large basilica, temples, baths, and an extensive aqueduct and cistern system that demonstrate sophisticated water management in a semi-arid environment.

Archaeological work has uncovered layers of occupation and destruction spanning over a millennium. The city was partially destroyed in the mid-8th century CE, likely in the 749 CE Sabbatical Year Quakes, after which the site was largely abandoned. Today, Gadara is one of Jordan’s major archaeological parks and a key site for understanding urbanism, identity, and transition along the Hauran frontier in antiquity.

Description, History, and Excavations

The Decapolis city of Gadara in northern Jordan is situated on a spur above the Yarmuk Valley opposite the Golan Heights. Its name derives from the Semitic word for stronghold. The town was referred to as Umm Qeis during the Middle Ages, the name deriving from the ancient Arabic mkes, meaning a border station.

Archaeological surveys indicate that Gadara was occupied as early as the seventh century BCE. The Seleucid ruler Antiochus III conquered it in 218 BCE, and in the early first century BCE its city wall was destroyed during the Maccabean invasion. But the damage was repaired and the city returned to Seleucid hands. Pompey took the city in 64 BCE and added it to the Decapolis. Rome rewarded King Herod with rule over Gadara in appreciation of Herod’s efforts to weaken Nabatean control over the region’s trade routes. The city reached its peak in the second century CE and became the home and birthplace of many writers and philosophers, prompting Meleagros to compare it with Athens. Strabo notes that visitors to the nearby hot springs of Ḥammat Gader, located on the northern bank of the Yarmuk Valley, relaxed in Gadara after bathing. Economic problems became evident in the third century CE, with the abandonment of certain building activities. In Byzantine times, the city was the seat of a bishop; a few churches were built. It declined in the sixth century, and in 636 CE, a decisive military clash between Byzantine Christians and Arab Muslims took place not far from it. Nevertheless, widespread destruction in the city was caused only later, by the earthquake of 748/749 CE.

Excavations at Gadara were mainly carried out by the German Protestant Institute in ‘Amman, under U. Wagner-Lux, T. Weber, and S. Kerner; and the German Archaeological Institute, under A. Hoffmann. During the earliest phase of settlement, the acropolis was defended by only four massive but unconnected towers of well-laid masonry. Later, in the second century BCE, the first city wall included the acropolis and a terrace to its north, where a Doric tetrastyle temple dedicated to Zeus was built. The Late Roman city wall ran much further west and north. The city had a long east–west street (decumanus maximus) crossed by shorter streets. The two circular towers of the western city gate—only their foundations preserved—flank the decumanus, while 400 m to the west are the remains of a triple arched gateway, which marked the extension of the city boundary in the latter half of the second or early third century CE, built together with the hippodrome. A nymphaeum is also located on the decumanus.

There are two theaters in Gadara, and a third located at the nearby hot springs of Ḥammat Gader. The largest is the north theater, but the best preserved is the west theater, built of black basalt stone and dating to the first and second centuries CE. Next to the west theater is a paved and colonnaded terrace, supported on the west by vaulted structures used as shops in Roman times. During the Byzantine period, an octagonal basalt church with a limestone-paved atrium was built on the terrace. The roof is supported by Corinthian capitals, taken from an earlier temple. Remains of a basilical church were exposed between the octagonal church and the west theater.

A residential area lies to the east of the west theater. Today, it is covered by the remains of an Ottoman village, built of masonry taken mostly from ancient buildings. The houses were decorated with geometric wall paintings and molded plaster.

Water was supplied to the city by two large aqueducts—primarily subterranean tunnels—conveying water from several springs to its east, among which were ‘Ein Gadara, and ‘Ein et-Trab, the latter located some 12 km away from the site. Several structures for water distribution have been found inside the city, diverting the water to the bath complex, nymphaeum, and dwellings.

Discussion

El‑Khouri and Omoush (2015:14) identified two phases of Abbasid occupation at Gadara: the first from 750–800 CE, and the second from 800–1000/1050 CE. They reported "ancient wall destruction (fallen stone layers)" beneath Abbasid layers in Squares F5 and F6. They also described the reuse of architectural elements and the destruction of a mosaic floor in earlier strata (El‑Khouri and Omoush, 2015:16–17). The dating was based on pottery.

Vriezen and Mulder (1997:323) reported that two churches in Gadara were destroyed by an earthquake, "presumably the earthquake of 749." These churches, located on the Terrace at the western slope of the Acropolis, consisted of a centralised church tentatively dated to the early 6th century and a basilica dated to the mid-7th century. Both were constructed over earlier Roman remains, and both were destroyed in the mid-8th century event.

Walmsley (2007) reported that "at Jadar [Gadara], on a ridge overlooking Lake Tiberias, the columns of the main east-west decumanus were toppled by the earthquake..., permanently terminating the late antique configuration of the town."

El-Khouri and Omoush (2015:14) identified two phases of Abassid occupation - the first from 750-800 CE and the second from 800 CE to 1000/1050 CE. El-Khouri and Omoush (2015:15) noted the presence of ancient wall destruction (fallen stone layers) in many squares underneath the Abbasid layers, especially in Squares F5 and F6. They also noted the reuse of architectural elements in Abbasid constructions as well as prior destruction of a mosaic floor (El-Khouri and Omoush, 2015:16-17). Dating was based on pottery.

Vriezen and Mulder (1997:323) reported that two churches in Gadara were destroyed by an earthquake presumably the earthquake of 749.

The ruins near Umm Qays (ancient Gadara) were surveyed in 1974 by a team from the German Protestant Institute for the Archaeology of the Holy Land headed by Ute Wagner-Lux. The ruins of the ancient buildings cover a site measuring approximately 1600 x 450 m consisting of a walled city area and an extramural area. Inside the walled city, two areas can be discerned: an Acropolis (approximately 250 x 250 m) in the east and a large Lower City in the west. The main street of the city, Decumanus Maximus, runs east-west.

Wagner-Lux and her team made a series of excavations on the large Terrace, situated at the bottom of the western slope of the Acropolis in 1976-1979 and in 1992. This site was labelled Area I. The Terrace, measuring 95 x 32 m, is bounded on the north by the Decumanus Maximus, to the south by a Roman theatre, whereas to the west a street, a cardo, aligned with vaulted rooms built against the Terrace's retaining wall, ran south from the decumanus to the theatre. In 1977 and in 1979 the northern end of the cardo (Area III) was excavated (FIG.1).

The Terrace may be divided roughly into three parts. In the northern part (32 x 32m), a colonnaded courtyard (a so-called atrium) was found. The courtyard is entered from the Decumanus Maximus by means of three entrances. The inner space was open to the air and on three sides (perhaps on all four sides) surrounded by a colonnade and a covered passageway. A line of rooms along the eastern side of the terrace open onto the eastern passageway.

In the central part, a church complex has been excavated, which consists of two churches. The larger one is situated right in the middle of the Terrace. It is a church of the "centralised type" consisting of a square building with a narthex attached to its west side. The second church is of the "basilica type". It is built against the south wall of the centralised church. The construction of the centralised church has been tentatively dated to the first half of the sixth century. Then, there was a courtyard to the south of it, similar to the one on its northern side.

The basilica was built at a later date, that is in the middle of the seventh century. Both church buildings were destroyed by an earthquake presumably the earthquake of 749.

The centralised church and the colonnaded courtyard represent the Byzantine building phase on the Terrace. The basilica is attributed to the Late Byzantine or the Early Omayyad Period. Underneath the floors of the church buildings and the courtyard, a pavement from the Roman period has been found. To the Roman phase also belong the Terrace's retaining walls and the structures along the cardo and Decumanus Maximus. This building phase has been tentatively dated to the end of the first or the beginning of the second century AD.

Chat GPT Summary of Archaeoseismic Evidence

Excavations at Gadara (Umm Qais) in 2011 revealed two distinct Abbasid occupation phases: the first from 750–800 CE and the second from 800–1000/1050 CE. These were separated by architectural, stratigraphic, and ceramic changes observed in domestic and open areas (pp. 14–15).

Beneath the Abbasid deposits, the authors reported evidence of pre-Abbasid wall collapse, described as "ancient wall destruction (fallen stone layers)," especially concentrated in Squares F5 and F6. This damage appeared just below the Abbasid floor levels and was visible in the form of crushed stones, collapsed masonry, and fallen wall lines that had not been reconstructed before the Abbasid rebuilding (p. 15).

The reuse of architectural elements such as door frames and thresholds was noted in later Abbasid construction. This included the apparent recycling of a mosaic floor—now damaged—into the foundations of a new structure, suggesting intentional reoccupation following destruction of an earlier building (pp. 16–17).

While no specific earthquake is named, the stratigraphic position of the destruction directly beneath early Abbasid layers, coupled with the lack of post-destruction restoration before Abbasid reoccupation, provides indirect evidence for a seismic event that likely predates or coincides with the mid-8th century transition.

Vriezen and Mulder (1997)

Chat GPT Summary of Archaeoseismic Evidence

Excavations at the Terrace of Umm Qays (ancient Gadara) revealed two churches—one of the centralised type, and one of the basilica type. Both were reportedly destroyed by an earthquake, “presumably the earthquake of 749.”

The centralised church was built in the first half of the 6th century, while the basilica dates to the mid-7th century. Their joint destruction in a single seismic event strongly suggests a mid-8th century terminus ante quem for their collapse.

The seismic destruction is stratigraphically significant, as the churches were constructed atop earlier Roman-period retaining walls and pavements on the Acropolis-side Terrace. spolia from these Roman structures were reused in the Byzantine construction. No later structural rebuilding of the churches was documented, consistent with abandonment after the earthquake.
