Introduction
Introduction

Lod, ~15 km. southeast of Tel Aviv, has a long history of occupation. It is mentioned in the list of Canaanite towns conquered by Thutmose III in the fifteenth century BCE and in the Hebrew Bible, the New Testament, and the Quran (Jacob Kaplan in Stern et al, 1993). After the Muslim conquest in 636 CE, Lod (then named Lydda) became the capital of Jund Filistin. In 715/716 CE, the capital was moved to the newly formed city of Ramla ~3 km. away. Historically, Ramla has suffered frequent earthquake damage and appears to be susceptible to liquefaction. By extension, Lod should also be susceptible to liquefaction as both locations rest on soft unconsolidated sediments in a flat coastal plain which in times past likely had a relatively shallow water table.

Lod

Identification and History

The ancient mound of Lod is situated near the southern bank of Nahal Ayalon (Wadi el-Kabir) about 15 km (1 mi.) southeast of Tel-Aviv. It is completely covered by modern buildings, except on the northern side, where the edge of the mound was swept away, thus forming a section 2.5 m deep. Lod is first mentioned in the list of Canaanite towns conquered by Thutmose III in the fifteenth century BCE. It appears later only in the genealogical list of the tribe of Benjamin in connection with the wanderings of the Elpaal family and their settlement in the northern Shephelah (I Chr. 8: 12). B. Mazar accordingly considers that the town lay in ruins during most of the Late Bronze and Iron ages and was resettled only in the time of Josiah. Lod is also mentioned in the context of the return of the people from the Babylonian Exile (Ezra 2:33; Neh. 7:37, 11:35). The town is frequently mentioned in the Hellenistic and Roman periods. Under the Emperor Septimius Severus, it was granted the status of a city and received the name of Diospolis. After the Arab conquest, its earlier name was restored.

Excavations in 1951 and 1952

From December 1951 to January 1952, J. Kaplan conducted exploratory excavations at the site on behalf of the Israel Department of Antiquities and Museums. Three small areas were examined:

  • area A - the northern edge of the mound
  • area B - the two sides of a small ravine
  • area C - a level area north of the above-mentioned ravine
In area A, a trench (10 by 2.5 m) was dug running from the base of the mound toward its upper part. Here, below surface level, part of a circular structure built of rubble was exposed. Beneath the structure, a mud-brick wall had been built on the virgin white sandy soil. These two lower strata were found to be identical with the lowest strata of the mound visible in the section. Altogether, four phases of occupation could be distinguished in the section, all dating to the Early Bronze Age I.

In area B, on the two banks of the small ravine, a dump of gray earth was discovered with pottery from different periods, mainly from the Chalcolithic cultures in Israel: Wadi Rabah, stratum VIII at Jericho, and Ghassulian ware. The pottery of the first two types included sherds of low-neck jars, splay-ended loop handles, and black-burnished ware. Among the Ghassulian sherds were loop handles with triangular section, goblets, and churns.

In area C shallow cavities were found-the remains of pits dug into the white sand-that contained Neolithic pottery. Most of the pottery was characteristic of Jericho IX ware - simple and coarse ware made with a large quantity of straw, plain burnished ware, and decorated pottery with a red-painted chevron pattern, and typical Jericho IX handles, including rough loop handles, cylindrical knob handles, and triangular ledge handles.

Tel Lod

Introduction

Numerous salvage excavations were conducted on Tel Lod during the 1990s. The stratigraphy of the mound differs from area to area, but it appears that, except for a few short gaps, it was occupied from the beginning of the Pottery Neolithic period, through the Bronze and Iron Ages, and intermittently in later periods to the present. The site is located at a distance from major trade routes and was never fortified. The earliest settlement appears to have been situated at the northern part of the mound, alongside the streambed. During the Middle Bronze, Late Bronze, and Iron Ages, the settlement moved about half a kilometer to the south. In the Roman and Byzantine periods, the mound was largely abandoned and settlement concentrated to its south, in the area of today’s Old City of Lod.

Excavations at Tel Lod were conducted in 1995 on behalf of Tel Aviv University by H. Khalaily and A. Gopher, and later on behalf of the Israel Antiquities Authority: in 1996 by E. Yannai and R. Badich, in 1997 by E. van den Brink, and most extensively in 2000 by E. Yannai and O. Marder

Ramla

Identification

According to scholars, the name Ramla derives from the Arabic word raml, meaning "sand," probably referring to the sand dunes on which the city was built, about 4 km (2.5 mi.) south of Lod and 15 km (9 mi.) southeast of Tel Aviv (map reference 138.148). Ramla was founded in the early eighth century (712-715 CE) by the Umayyad caliph Suleiman ibn 'Abdel-Malik (brother of Walid I), the former governor of Jund Filistin (the District of Palestine). It is the only city in Palestine founded by Arabs. Ramla was first made the capital of the newly created province Filistin, which included the regions of Judea and Samaria. According to accounts by Arab geographers, Ramla was built from the ruins of nearby Lod. This destruction was not only expressed in the preferred status granted to Ramla, but also in the reuse in its construction of building materials from the ruins of Lod. To promote its growth, part of the population of Lod was also moved to Ramla.

With the city's founding, many installations and buildings, such as cisterns, a drain channel, the House of Dyers, and the mosque, were erected. Most of the Umayyad city is now covered by later construction. Only in the Umayyad mosque, called the White Mosque (which was later renovated, probably in the Ayyubid period), were several remains of that period preserved. Its minaret, which was rebuilt in the Mameluke period, is the most prominent structure of medieval Ramla.

Excavations at the White Mosque in 1949

Excavations at the White Mosque were conducted by J. Kaplan in 1949 on behalf of the Ministry of Religious Affairs and the Israel Department of Antiquities and Museums. The excavations attempted to ascertain which buildings, both above ground and subterranean, belonged to the original mosque enclosure. It was revealed that the mosque enclosure was built in the form of a quadrangle (93 by 84 m), with its walls oriented to the cardinal points. It included the following structures: the mosque itself; two porticoes along the quadrangle's east and west walls; the north wall; the minaret; an unidentified building in the center of the area; and three subterranean cisterns.

Excavations in 1965

Of the various excavations carried out in different areas of Ramla, the major undertaking was conducted in October 1965 by M. Rosen-Ayalon and A. Eitan, on behalf of the Israel Department of Antiquities and Museums. This excavation was concentrated in the southwestern part of the town; however, several trial soundings on a smaller scale were dug simultaneously in an effort to broaden the general picture.

Excavations between 1990 and 2003

In the wake of development and construction projects, 79 salvage excavations and soundings were conducted in various parts of the city of Ramla in 1990–2003. While most of the excavations were probes at building sites or under modern streets, a number of large-scale excavations were also carried out in areas north and west of the Old City and north and south of the White Mosque. Several excavations were also conducted around the Ramla bypass road northeast of the Old City and in the western suburbs of the modern city. The aqueduct that carried water to the city from the springs at Tel Gezer was also examined in salvage excavations. Although they were conducted in non-contiguous areas, the many excavations make it possible to arrive at a tentative reconstruction of Ramla in the Early Islamic, Mameluke, and Ottoman periods. In addition to the excavations, an architectural survey of the buildings from the Middle Ages and the Ottoman period was conducted by A. D. Petersen in the center of the city.

The Ramla Aqueduct

The Umayyad aqueduct to Ramla is referred to as Qanat Bint el-Kafir (“The Heretic Daughter’s Aqueduct”) on the map of the British Survey of Palestine of 1882; the source of this name is unknown. In 1950, R. Gophna and J. Kaplan mapped a section of the aqueduct at Moshav Ptah ya. In 1998–2001, A. Gorzalczany and Y. Zelinger conducted salvage excavations along its course and exposed large sections of it.

Most of the course of the c. 10-km-long aqueduct can be reconstructed, but its water source and point of entry to Ramla have not yet been ascertained. Its source should probably be identified with the group of springs located in the vicinity of Abu Shusha, near Gezer. From there it runs northwest, entering Ramla from the south or southwest.

The aqueduct consists of a foundation of fieldstones bonded with cement and two parallel walls of dressed limestone masonry. The walls (40–50 cm wide) are plastered on their inner and outer faces and overlaid with another layer of fieldstones mixed with gray cement. The overall width of the aqueduct is about 1.5 m. Its channel is covered with flat limestone slabs averaging 30 by 80 cm and 12–15 cm thick, laid widthwise. The inside of the aqueduct was covered with an approximately 1-cm-thick layer of light red plaster composed of quartz, sherds, and shells applied to a base of sherds. Another layer of plaster was applied above this, somewhat altering the cross-section of the channel (specus), which varies along its length. In the eastern part of the aqueduct its width was distorted by the movement and inward collapse of the supporting walls and this section is at present completely blocked. Soundings made in the middle of the aqueduct revealed that it was dug into the virgin hamra soil. The aqueduct descends to a depth of c. 0.7 m and is set on a slightly wider foundation (1.50 m) made of small stones bonded in gray mortar, reaching a depth of 0.7 m below the base of the channel.

In the middle of the excavated segment of the aqueduct is a cylindrical shaped manhole, 1.30 m in diameter and preserved to a height of 0.50 m above the level of the cover stones. The superstructure is hollow and has a hexagonal internal horizontal cross-section (0.70 m in diameter). The manhole was built above a square opening set between the cover stones and is large enough for a person to enter. A similar manhole was exposed 45 m to the west, but its superstructure had collapsed. No cover stones were found in situ in the westernmost part of the exposed segment, probably having been robbed in antiquity.

Discussion

Gorzalczany (2009b) described 8th century CE earthquake evidence as follows:
Evidence of a major earthquake was discerned in Areas J2 and K1 (see Fig. 2 - site map); it included cracks along the walls of installations, large sections of collapse composed of neat ashlar stone construction that had not been robbed, floors that had dropped and walls that curved in unexpected directions. Wall collapse, which had been intentionally covered over with soil and hamra to save the building stones from being plundered, was observed. It seems that the residents of the town were concerned with the quick restoration of the settlement’s activity. Especially interesting was a series of jars, some positioned upside down, which were discovered in situ, smashed inside a room that was apparently used for storage [Fig. 6 ]. The jars dated to the first half of the eighth century CE and they seem to have been all damaged simultaneously in the same event. The room was leveled and quickly refurbished in an attempt to regain its capacity for industrial manufacture as soon as possible. The renovation of the room included the construction of new walls, with which jars dating to the second half of the eighth century CE were associated and preserved intact (Fig. 9 ). It therefore seems that we have here a small, rare chronological window, which enables us to date the earthquake.

Indisputable proof of the earthquake occurrence was found in the balks of Area K1, where a fault in the layers of sand and hamra, which were split due to a fissure, stands out prominently (Fig. 10 ). One side of the layers in the section was lower than the other side. The fissure continued along several excavation squares and it caused a plaster floor and a column base that stood above it to sink 1.5 m [Fig. 4 ]. Such vertical movement of layers could only be caused by a powerful seismic event. An opposite fracture was discerned elsewhere on the site, where the movement was not only vertical but also horizontal, causing the layers to climb one atop the other [Fig. 5 ]. It appears then that archaeological evidence of an earthquake, which occurred close to Ramla in the middle of the eighth century CE, can be pointed to for the first time. The dating is firmly based on the pottery and it is feasible that this is the famous earthquake of the year 749 CE.
Thus, we have earthquake evidence which is precisely dated and well described. The 1.5 meter sinking of the column base (Fig. 4 ) strongly suggests that this site experienced liquefaction. In fact, Gorzalczany and Salamon (2018) report that the column base and associated plaster floor which collectively sank 1.5 m [Fig. 4] were underlain by neatly superimposed layers of sand and hamra which constituted an artificial fill. Gorzalczany and Salamon (2018) found evidence that this artificial fill was placed in a foundation trench which was dug to set up an antilia type water well (Avitsur 1976: 60-63; Ayalon 2000) which abutted the plaster floor and columns. The presence of an antilia type water well indicates a shallow water table and a shallow water table, uncompacted fill, and alternating layers of strata with differing permeabilities is a veritable recipe for liquefaction during seismic events. Liquefaction, which is driven by temporal increases in pore pressure that cannot dissipate can be enhanced if pore pressures in the more permeable sandy layers cannot dissipate because they are surrounded and sealed by less permeable layers. Gorzalczany and Salamon (2018) report that the entire antilia installation - the pit and the lifting superstructure device together with the layers of fill and the occupation layer abutting them - collapsed and sank several meters. Damage to surrounding areas indicates that the pit (Fig. 5) constituted the central axis of the fall and the sand layers around the antilia [that appeared] broken in a stepped formation (Fig. 5) encompassed the pit.

Gorzalczany and Salamon (2018) added an observation of building stones of walls that had collapsed in a clear, `orderly' pattern found in situ (Fig. 2 ). Such an orderly fall pattern can be a diagnostic effect of failure due to an earthquake. Gorzalczany and Salamon (2018) report that no fault traces were found underneath the affected areas and no faults were indicated on geologic maps suggesting that the observed archeoseismic damage was due to shaking away from the epicenter of the causitive earthquake.

The White Mosque at Ramla

Rosen-Ayalon (2006:72) suggested that renovations to the White Mosque at Ramla in the second building phase was a reaction to seismic damage to the first phase from a mid 8th century CE earthquake - noting that although not all the excavators discovered signs of destruction compatible with an earthquake, some indeed relate to this possibility. Rosen-Ayalon (2006:72) described the physical archaeoseismic evidence as inconclusive.

The evidence is inconclusive, since a significant proportion of the finds was found in disturbed stratigraphy. In other words, even if there had been significant damage, this may not have been evident in excavation. However, even minimal disturbance — not of the magnitude caused by the eleventh-century earthquake — may have been sufficient to warrant the renovations.
By comparing architectural elements (e.g. pointed arches) of the 3 subterranean cisterns of the Phase 2 mosque enclosure with architectural elements (e.g. pointed arches) of a subterranean cistern known as 'the pools of Saint Helena' or the 'Aneziya', Rosen-Ayalon (2006:74) concluded that Phase 2 mosque construction took place around 788/789 CE as construction of 'the pools of Saint Helena' is dated by inscription to A.H. 172 (788/789 CE).

11th century CE Earthquake

Rosen-Ayalon (2006:72) suggested that renovations to the White Mosque at Ramla in the third building phase occurred after the structure was damaged in the earthquake of 1033 CE. She suggested that third phase construction was carried out in 1190 CE and should be attributed to Salah al-Din. Rosen-Ayalon (2006:72) mentions that traveller Nasir i-Khosero [] visited Palestine one decade after the earthquake [of 1033 CE] and grieved for the city of Ramla which was devastated in the early eleventh-century earthquake. On page 64 a passage in a French translation of Sefer Nema by Nasir i-Khosero we can read:

The area of the great mosque is three hundred paces by two hundred. An inscription, placed above the soffèh (bench), relates that on Moharrem 15, 425 ( December 11, 1033), a violent earthquake overthrew a large number of buildings but none of the inhabitants were injured.
It should be noted that textual accounts also state that Ramla suffered damage during the earthquake of 1068 CE. The Crusaders arrived in 1099 CE and occupied Ramla after which a number of battles were fought in the area which could/would have delayed mosque renovations.

Discussion

Kletter (2005:57-60) observed a tilted wall (W2) in an early Islamic structure in Square E1 of Area A situated within 'Opher Park below newly constructed ‘Opher School in Ramla. Kletter (2005:60) noted that the tilt may have been due to an earthquake although the true cause for this feature is unknown. Two phases were identified in the tilted wall (W2) and both phases (II and I) are tilted. The site appears to have been difficult to date. Kletter (2005:95) noted that the site seems to have been abandoned at the end of Phase I, although no traces of fire or violent destruction were detected. Kletter (2005:95) dates the abandonment to some time within the eleventh century CE as no find can unequivocally be dated to a later period.

  • Indisputable proof of the earthquake occurrence was found in the balks of Area K1, where a fault in the layers of sand and hamra, which were split due to a fissure, stands out prominently (Fig. 10). One side of the layers in the section was lower than the other side. The fissure continued along several excavation squares and it caused a plaster floor and a column base that stood above it to sink 1.5 m [Fig. 4]. Such vertical movement of layers could only be caused by a powerful seismic event. An opposite fracture was discerned elsewhere on the site, where the movement was not only vertical but also horizontal, causing the layers to climb one atop the other [Fig. 5]. - Gorzalczany (2009b)

  • Gorzalczany and Salamon (2018) report that the column base and associated plaster floor which collectively sank 1.5 m [Fig. 4] were underlain by neatly superimposed layers of sand and hamra which constituted an artificial fill. Gorzalczany and Salamon (2018) found evidence that this artificial fill was placed in a foundation trench which was dug to set up an antilia type water well (Avitsur 1976: 60-63; Ayalon 2000) which abutted the plaster floor and columns. The presence of an antilia type water well indicates a shallow water table and a shallow water table, uncompacted fill, and alternating layers of strata with differing permeabilities is a veritable recipe for liquefaction during seismic events. Liquefaction, which is driven by temporal increases in pore pressure that cannot dissipate can be enhanced if pore pressures in the more permeable sandy layers cannot dissipate because they are surrounded and sealed by less permeable layers. Gorzalczany and Salamon (2018) report that the entire antilia installation - the pit and the lifting superstructure device together with the layers of fill and the occupation layer abutting them - collapsed and sank several meters. Damage to surrounding areas indicates that the pit (Fig. 5) constituted the central axis of the fall and the sand layers around the antilia [that appeared] broken in a stepped formation (Fig. 5) encompassed the pit.

Rebuilding ? White Mosque at Ramla
  • Rosen-Ayalon (2006:72) suggested that renovations to the White Mosque at Ramla in the second building phase was a reaction to seismic damage to the first phase from a mid 8th century CE earthquake - noting that although not all the excavators discovered signs of destruction compatible with an earthquake, some indeed relate to this possibility. Rosen-Ayalon (2006:72) described the physical archaeoseismic evidence as inconclusive.
    The evidence is inconclusive, since a significant proportion of the finds was found in disturbed stratigraphy. In other words, even if there had been significant damage, this may not have been evident in excavation. However, even minimal disturbance — not of the magnitude caused by the eleventh-century earthquake — may have been sufficient to warrant the renovations.
?
Although this archaeoseismic evidence requires a minimum Intensity of VIII (8) when using the Earthquake Archeological Effects chart of Rodríguez-Pascua et al (2013: 221-224), much of the damage and collapse may have been primarily due to liquefaction rather than strength of shaking on the structures. Rapid rebuilding efforts and attempts to cover up stone tumbles suggest that this wasn't an earthquake which wiped out the city due to widespread collapse. As it appears that liquefaction was a driving factor for the damage, the Intensity for this earthquake is estimated at VII (7) based on Rodríguez-Pascua et al (2013)'s assessment for liquefaction.

Rebuilding ? White Mosque at Ramla
  • Rosen-Ayalon (2006:72) suggested that renovations to the White Mosque at Ramla in the third building phase occurred after the structure was damaged in the earthquake of 1033 CE. She suggested that third phase construction was carried out in 1190 CE and should be attributed to Salah al-Din. Rosen-Ayalon (2006:72) mentions that traveller Nasir i-Khosero [] visited Palestine one decade after the earthquake [of 1033 CE] and grieved for the city of Ramla which was devastated in the early eleventh-century earthquake. On page 64 a passage in a French translation of Sefer Nema by Nasir i-Khosero we can read:
    The area of the great mosque is three hundred paces by two hundred. An inscription, placed above the soffèh (bench), relates that on Moharrem 15, 425 ( December 11, 1033), a violent earthquake overthrew a large number of buildings but none of the inhabitants were injured.
    It should be noted that textual accounts also state that Ramla suffered damage during the earthquake of 1068 CE. The Crusaders arrived in 1099 CE and occupied Ramla after which a number of battles were fought in the area which could/would have delayed mosque renovations.
?
The collapsed walls requires a minimum Intensity of VIII (8) when using the Earthquake Archeological Effects chart of Rodríguez-Pascua et al (2013: 221-224. However, since Ramla is subject to liquefaction, local bedrock intensity is downgraded to VII (7).

Notes

  • Ramla is based on the Arabic root word Raml which means sand (Rosen-Ayalon, 2006).
  • The book Sefer Nameh was written by Nasir i-Khosero based on a 7 year travelogue beginning in 1046 CE. His visit to Ramla would have thus been between 1046 and 1053 CE - i.e. after the 1033 CE Quake but before the 1068 CE Quake.
