 Textiles were sold around the north transept, while meat, vegetable and fuel sellers congregated around the south porch.Money-changers (an essential service at a time when each town or region had its own currency) had their benches, or "banques", near the west portals and also in the nave itself.Wine sellers plied their trade in the nave to avoid taxes until, sometime in the 13th century, an ordinance forbade this.
