Roman Micro-Mosaic

Micromosaico Romano

The creation of miniature mosaic pictures from tiny glass tesserae (filati) — rods of colored glass drawn to hairlike fineness, cut into fragments as small as 0.2mm — set in a wax or plaster ground to produce jewelry, tabletop panels, and decorative objects that replicate famous paintings and ancient Roman motifs at jewelry scale, in a technique exclusive to Rome and developed at the Vatican mosaic studios from the late 18th century.
