Evidence of the very early use of the column on the same site was forthcoming in the discovery of a series of eight brick bases, situated some thirteen feet from the ancient building of Ur-Ninâ, the charred remains of pillars of cedar-wood by which these bases were once surmounted being still visible. Probably the most familiar example of the use of the column in Babylonia, afforded by the excavations, is that of the Court of columns at Nippur (cf. Pl. X). This court is over forty-eight feet square; its floor consists of a thick pavement made of unburnt bricks, and is over six feet in depth; around three of the sides of this square, Peters tells us, ran a kind of edging formed by a double row of burnt bricks, out of which arose four brick columns, round in shape, but resting on square brick pillars which descended some three feet or so below the surface; the fourth side was without doubt similarly occupied with columns, but nearly every trace of even the foundations of them has been washed away owing to the slope of the hill. On the other sides of the platform the columns remain standing to a height of about three feet; they appear to have tapered upwards, the diameter at the base being just over three feet. They were built of bricks especially made for the purpose: these bricks, in shape, are segments of circles, the apexes of which are truncated, and the hollow thus left in the centre of the circle compounded of these deformed segments was filled in with fragments of bricks. The segmentary bricks are well baked though somewhat brittle, and they were laid in mortar. According to Peters, these columns were carefully dressed with a sharp instrument, to remove any irregular projections there might be owing to the malformation of any of the component bricks. The columns are moreover not arranged with mathematical accuracy, being only roughly equidistant from one another. The corner-columns differ from the others in being half-round and half-square. Peters dates this colonnade in the second millennium and assigns it to the Cassite period. Hilprecht however believes it to be a product of the Parthian times, and dates it about 300 B.C.
