English: Fragment of a 'Saf' carpet, intended for a place of public prayer such as a mosque. Inscribed "Master 'Ali Nushabadi" (otherwise unknown), who could be manufacturer or weaver. This fragment has been dated to the first half of the fourteenth century by reason of the particular letter forms of the inscriptions, which makes it the earliest extant example of a flat-weave carpet from Islamic Iran. Cotton. 104 x 46 cm. Iran, first half of the 14th century. Hermitage Museum ИР-2253
