Finely knotted in wool on a silk foundation, and embellished with metal threads, this is the largest collection of these carpets known outside the Topkapi Saray (Istanbul). For a century, their origin and chronology have been the source of considerable debate; and the discovery of three carpets in Guimarães offers a unique opportunity to reflect upon these problems. They take their name from the collector George Salting (1835-1909) who donated a significant example to the Victoria & Albert Museum (London), which was originally attributed to 16th-century Iran. However, the vivid colours of this and other carpets, and existence of similar examples in the Topkapi, led later historians to argue that they were Turkish rugs from the 18th or 19th centuries, and possibly even forgeries of classical Persians carpets. Given this complex historiography, resolving the question of the origin and date of the „Saltings‟ is obviously imperative. The type of materials used to make a carpet and how they are prepared can reveal groups of carpets and help to establish their origin and/or date [1]. This type of data can also indicate whether these groups reflect a single, coherent production of short duration, or multiple workshops and a wide historical timeline. Only partial scientific information is currently available for the „Saltings‟ [2], and hence, this study takes a multidisciplinary approach to the problems of their origin and date. Results and Discussion All fibres, dyes, mordants and metal threads where analysed through many techniques, in order to understand structural and material characteristics of this carpets; and a more detailed study was applied to the reds.

Moreover, as “a carpet can only be as old as its design” [3], all of the stylistic features are also consistent with Safavid art. Although these few elements are significant, they are not necessarily conclusive, of course, and only the AMS Radiocarbon results for Medallion Carpet confirms a more precise date between the late 15th and mid-17th century.
