Repouss is a metalworking technique wherein a malleable metal is shaped by hammering from the reverse side to create a design in low relief. The metal is worked from the back to create a raised area on the front. This process is often combined with chasing, where the front of the material is hammered to refine the design. A practical example is seen in ancient Greek bronze shields decorated with intricate scenes hammered from the reverse.
This technique offers the distinct advantage of creating three-dimensional forms from sheet metal without removing any material. Its longevity and widespread adoption across cultures and time periods indicate its effectiveness in producing durable and visually compelling artwork. From ancient Egyptian funerary masks to Renaissance armor, the method has been used to impart detail, texture, and visual interest to a variety of objects.
