In the Sasanian-era bazaars, each group of artisans had its own specific section, called rāste in Persian. We know this information from the Denkard, which talks about the rules that existed "about the series of shops in the bazaar belonging to various artisans." (VIII, Chapter 38) The Denkard also mentions a list of professions who occupied a section of the bazaar, like the blacksmiths (Middle Persian: āhengar) and barbers (Middle Persian: wars-wirāy).
