Byzantine, 6th century, made in Northern France (2.5 x 1.5 cm)
Opus interrasile was a technique used by goldsmiths to make elegant
jewelry from the 200s through the 600s. Designs were traced onto sheets
of gold; the background was punched with holes of various sizes to
highlight the pattern; and fine details were then worked on the surface.
The patterns formed by piercing the metal ground encouraged the play of
light and shadow across an object’s surface.
