The houses of the Campidano are mostly built of sun-dried unbaked bricks.
Half a day's journey beyond, at a point where two great wadis enter the Euphrates, on the Syrian side, stands Jabriya, an unidentified ruined town of Babylonian type, with walls of unbaked brick, instead of the stone heretofore encountered.
Was first formed in 470 B.C. by the "synoecism" of the neighbouring villages, the river Ophis flowed through the midst of it, and the Spartan king Agesipolis dammed it up below the town and so flooded out the Mantineians and sapped their walls, which were of unbaked brick.
Accordingly, when the city was rebuilt in 370 B.C., the river Ophis was divided into, two branches, which between them encircled the walls; and the walls themselves were constructed to a height of about 3 to 6 feet of stone, the rest being of unbaked brick.
This is the remains of the raised platform of unbaked brick, faced with baked bricks and stone, on which stood the principal palaces and temples of the city, the cone at the N.W.
