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.
