Transparent deep blue glass with numerous bubbles, some dark brown inclusions, and few dark blue streamers; blown, gilded, enameled, scratched. The rim is plain, with rounded lip; the wall (Th. 0.1 cm) is straight, tapering slightly and curving in at the bottom; the base is plain, with a circular pontil mark (D. 1.3 cm). The surviving decoration was executed in gold applied in suspension and enamel. It consists of one continuous horizontal border below the rim and the remains of three horizontal bands of roundels arranged in a quincunx. Each band contained three contiguous roundels, all of which have borders comprising two concentric circles that enclose one concentric ring of small open circles and two additional concentric circles, and has at the center a single plump bird standing in profile with its head up and wings folded. Details such as the eyes, the outlines of the wings, and the feathers are scratched through the gilding. Although the birds are similar, they are shown in three different attitudes; (1) standing to the right and looking forward, (2) standing to the left and looking forward, and (3) standing to the right with its head turned to look over its shoulder. The birds in the top row of roundels are arranged (from left to right) in the order 1, 2, 3; those in the bottom row are presumed to have the same order, although 2 is missing; and those in the middle row (beginning between 1 and 2 in the top and bottom rows) are presumed to have been in the order 3, 1, 2 (none survives). In front of each bird is row of crosses and stars, and behind it an arabesque.
