The striking blue color of this plate was achieved by adding cobalt to the glass fabric, and its surface has been engraved with various patterns arranged in concentric registers around a central roundel. The circular hole at the center indicates the place where a foot was once attached. This plate is important evidence of the active glass trade from west to east during the ninth and tenth centuries. Probably made in Syria, it was imported to Nishapur where it was found in the prosperous Tepe Madrasa section of the city. The fact that six dishes of this type were found in the crypt of the Famen Temple in China demonstrates the far eastern reaches of the trade routes that passed through Nishapur. Furthermore, the evidence from this temple, whose crypt was sealed in 874, provides an ante quem date for our plate.
This shallow plate has a plain rim with a rounded edge. The wall curves down and in, with a depression ( diam. 4 cm [1 5/8 in.]) at the center of the floor. Most of the floor is missing; similar plates have either a plain base or three applied feet (see, for example, Smith 1957, no. 605). The exterior has one continuous horizontal trail at the junction of the wall and the floor.
The interior is almost completely covered with engraved decoration arranged in four concentric bands with a roundel at the center. The outermost band is narrow and consists of a groundline supporting small, roughly semicircular scalelike elements, in which scales filled with transverse hatching alternate with scales that are empty except for a short transverse dash. The second, wider band, which has inner and outer borders,contains two ribbons twisted into a cable on a hatched background. The third band, the widest of all and with inner and outer borders, is divided into six equal compartments by radiating rows of bordered contiguous circles, which are alternately hatched and empty except for a single short dash.
Inside the compartments, two designs alternate. The first consists of crowded sprays of leaves with transverse hatching and berries that appear to be of multiple or aggregate form. The second design is divided into three triangles by double borders. The triangle at the center, with apex pointing toward the rim, contains a palmate leaf with five branches on a coiled stem. The other triangles have allover patterns of rhomboids that alternately are hatched or contain one short dash. The innermost band, which is narrow and framed by borders, contains a chain of contiguous circles with either transverse hatching or short dashes. Apart from the border, nothing of the central roundel survives.
Chemical analysis has revealed that the material here is a soda:lime:silica glass made with plant ash (Brill 1999a, vol. 1, p. 96, vol. 2, p. 196 [sample 6365]). Robert H. Brill compared this object with two fragments at Corning (55.1.110 and 55.1.111), both of which come from deep blue plates or bowls decorated on the inside with a central roundel and concentric bands of ornament. In both those cases, the glass was made with plant ash (Brill1999a, vol. 1, p. 96, vol. 2, p. 196 [samples 6349, 6350 ]).
It has been suggested that the palmate leaf is that of the hemp plant, Cannabis sativa (Brill1993, p. 63, n. 14), or the Chinese maple. Perhaps the other leaves and the berries are those of the white mulberry tree, Morus alba, the preferred food of silkworms. Palmate leaves with five branches occur on at least four other scratch-engraved vessels that are similar to this object. All four are among the treasures concealed in the crypt of the Famen Temple (Famensi), in northeastern China, in 874; one has four such leaves on coiled stems (An 1991, pp. 126-29, figs. 3, 5, 7, 8; Koch 1995, p. 500, fig. 41.2 and pl. 138.2).
