The city of Jerash in northern Jordan was badly damaged by an earthquake in AD 749. As a result of this, many parts of the city, including the Northwest Quarter, were abandoned and further construction ceased. Archaeological excavations in those parts of the city therefore reveal snapshots in time from the moment at which disaster hit. Of particular interest is the so-called ‘House of the Tesserae’, where archaeologists discovered a trough for the storage of pieces to be used in the construction of mosaics. The find, reported here for the first time, provides a unique insight into the practice of mosaic-laying during the Early Islamic Period.
