The form of this unusually small ewer is similar to that of the well-known Tiflis ewer that is dated 686-7 or 688-9 AD (Eva Baer, Metalwork in Medieval Islamic Art, New York, 1983, pl.166, p.192; A. S. Melikian-Chirvani, Islamic Metalwork of the Iranian World, London, 1982, p.25 and note 22, p.37). The faceting found here is unusual. While the Tiflis ewer is faceted it just has narrow vertical facets. The pattern of faceting here is closer to that found on a ewer that has been attributed to the Eastern Iranian World and a date of the 10th-11th century in the Victoria and Albert Museum (Melikian-Chirvani, op. cit., no.6, pp.45-6).
