Colorless with pale green tinge. Flaring, knocked-off rim with shallow S-shaped collar below; body with circular circumference and rounded bottom. Body formed into the shape of a marine bivalve mollusc (scallop) in relief with eleven ribs radiating from a deep ocellus or umbone in a fan pattern ; ribs become broader and have rounded ends below collar around rim; the ocellus is flanked to either side by a hemispherical bulge. Below the rim is a faint wheel-abraded line. Broken and repaired, with some internal cracks; pinprick and larger bubbles; faint weathering and iridescence.
Bowls made in in silver, bronze, and semiprecious stone and shaped to resemble a large seashell became popular in the Hellenistic period. Glass examples were also produced in early Roman imperial times, some cast and others mold-blown. This bowl however appears to be a later example of the blown variety; others, found mainly on the Rhine or Danube frontier, are dated to the fourth century A.D.
