Wall descends vertically and curves in at bottom. Exterior has broad band of scratch-engraved ornament with four roughly parallel horizontal border lines at bottom (upper border does not survive). Ornament consists of body, leg, and perhaps part of wing of bird standing in profile to right; in front of it, plant with curving stem and round or oval leaves on short stalks; below body of bird are two circular motifs; parts of bird, leaves, and circles have vertical and transverse hatching. Parts of two groups of short vertical lines project downward from bottom of border.
