Fragment of an Inlay Depicting a Fish

In ancient Rome, there was a high demand for colorful glass that could dazzle banquet guests alongside the expensive silver and gold serving wares meant to impress. Fragments like this one would have once been a part of larger mosaic dishes. The mosaic pattern was made by sagging molten glass into bowl-shaped molds, a technique used on many of these fragments is similar to millefiori, “thousand flowers” in Italian, a modern glass-making method in which tiny rods of colored glass are bundled together, wrapped in a sheet of glass, fused, and then thinly sliced to reveal swirls of a flower-like patterns. They were arranged side by side, sometimes together with bits of colored glass, and fused together with heat.
