Premise: The Rue du Roi-Ren?? will take you past some handsome 17th- and 18th-century?­ houses; and on the pretty, cobblestoned Rue des Tein?­tu?­riers you can see where the dyers used to work the paddlewheels for their Indian-style cloth in the little Sorgue river, emerging here from its underground course.

Hypothesis: The Sorgue river was also near the home of the merchants who would sell the dye.
