4th architectural phase earthquake
Bianchi (2019:210) reports that during
the final
architectural phase
of the Memorial to Moses basilica
on Mount Nebo, “the two upper rows
of the
synthronon
and the masonry of the
apse
in the
presbytery
were restored.”
In discussing the cause of this
restoration,
Bianchi (2019:210) notes 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 is
“related probably to the
earthquake
of 749 AD.”
At the same time,
Bianchi (2019:210) cautions that
“the morphology of this structure
may have been affected by the
geological instability of the
northern slope.”
Chronologically,
Bianchi (2019:210) concludes that
“the second half of the eighth
century well agrees with the
chronology of the pottery recovered
beneath the upper rows of
synthronon,” noting that most of
the sherds date to the late
Umayyad
period, with a smaller number
attributable to the
Abbasid
era. An inscription dated to 762 CE in a Chapel that was part of the
Monastery of the Theotokos may reflect post-quake rebuilding efforts and
provide a
terminus ante quem
(Piccirillo & Alliata, 1998:209-216).
