of globular form with long multifaceted neck, engraved to the body with two registers of roundels containing circle motifs, the shoulder with two concentric bands - 17.2 cm. high.

Note: Wheel-cut circles are one of the most frequently occurring motifs in glass found at Nishapur (see Jens Kroger, Nishapur Glass of the Early Islamic Period, New York 1995, pp. 129–135). It seems probable that the motif was first introduced under the Sasanians, and became very popular in the early Islamic period. The earliest examples, as here, tended to have larger central roundels within the circles; subsequently they were reduced to small conical elements.
