In contrast to most PETAG Tabriz carpets, such as the previous lot in the present sale, the design of this carpet is not a direct copy of any of the illustrated carpets in Sarre and Trenkwald's publication, Altorientalische Teppiche which are in the Österreichisches Museum für Angewandte Kunst in Vienna. Instead it copies a pair of 16th-century Tabriz carpets discovered in the Mosque in Ardebil, one of which was formerly in the Sarre Collection and is now in the Metropolitan Museum of Art, New York, (Kurt Erdmann, Seven Hundred Years of Oriental Carpets, Glasgow, 1970, pl.229, pp.182-83; M.S. Dimand and Jean Mailey, Oriental Rugs in the Metropolitan Museum of Art, New York 1973, fig.75, pp.52-53).
