These Roman cities became converted to the religion of Christ, and then not only were the sanctuaries of paganism transformed into Christian sanctuaries, but new churches were erected adapted to the new worship; houses, palaces, and tombs were built; even entire cities were founded. At length all these Christian cities were abandoned at the same time--probably at the epoch of the Mohammedan invasion--and since then they have not been touched. Except that earthquakes have thrown to the ground many of the walls and columns, they lack only beams and planks, or they would be perfect edifices, which soon might be made habitable again. But how intensely interesting the exploration of the district becomes when we learn that underneath these towns of Roman date are the dwellings of the earlier inhabitants! For example, _Burak_ is a city of the Hauran which has been identified with the episcopal city Constantia, founded, it is supposed, or at least embellished, by Constantine. But Rev. W. Wright tells us that while the houses seem to stand on a mound of black earth, they are in reality built on the foundations of houses of a more remote antiquity. In one place he descended to a depth of 16 or 18 feet, to see some pottery which had lately been discovered, and he found the walls at that depth formed of enormous undressed and unsquared stones, unlike the stones of the superstructure, which are small in size and have been better prepared for the walls. “Nor will it be doubted” (he says) “that beneath that raised mound are buried the remains of one of the ‘three-score cities’ that once existed in Bashan, and which still exist under changed circumstances, sometimes under different names.”
