Rheno-Mosan Enamel, Second Half of the 14th Century. The Plate Depicting Justitia Decorates the Foot of a Reliquary on Display in the Dom Schatzkammer in Aachen, Germany.

The Rheno-Mosan area is located in present day France, Belgium, Luxembourg and The Netherlands and is roughly enclosed by the Cologne-Trier-Liège triangle. During the late Romanesque and early Gothic periods, this area was famous for its champlevé enamel as well as for the high craftsmanship of the goldsmiths who toiled in the many workshops (mostly concentrated in monasteries).

Godefroid de Clair and Nicolas of Verdun were the main representatives and they are generally acknowledged as the precursors of the Gothic era.

Rheno refers to the river Rhine and Mosan to the Meuse river.
