This is from Howard's "The House of Arabu"* and describes the Sumerian city of Nippur c.3000 BC, but could well apply to a Shemitish city such as Nippr or Shumir:
* published in Wolfshead (1979), Eons of the Night (1996), and The Ultimate Triumph (2000)The party were proceeding leisurely down the broad white street, gaped at by the common folk who bobbed their shaven heads as they passed. The sun was not long up, but the people of Nippur were well astir. There was much coming and going between the booths where the merchants spread their wares: a shifting panorama, woven of craftsmen, tradesmen, slaver, harlots and soldiers in copper helmets. There went a merchant from his warehouse, a staid figure in somber woollen robe and white mantle; there hurried a slave in a linen tunic; their minced a painted hoyden whose short slit skirt displayed her sleek flank at every step. Above them the blue of the sky whitened with the heat of the mountain sun. The glazed surfaces of the buildings shimmered. They were flat-roofed, some of them three or four stories high. Nippur was a city of sun-dried brick, but its facings of enamel made it a riot of bright color.
