Glass cup with splayed foot
Translucent blue green.
Outsplayed tubular rim, folded over and in; tall curving neck, tapering downwards; thick projecting shoulder; squat, globular body; applied conical foot, formed from a separate gather, with edge cracked-off and ground flat; small, circular, flat bottom.
Eleven vertical ribs in high relief tooled out from shoulder down side of body.
Rim and body cracked with one hole in side; part of foot broken and missing; few bubbles; dulling, pitting, creamy brown weathering, and faint iridescence.
This cup or chalice bears a similarity to the ribbed bowls also displayed here (91.1.1247, .1346), but the treatment of the rim and the addition of the foot make it a very unusual example of Roman blown glass tableware.
