The sophisticated construction and elegant design on this aristocratic cloak fastener are probably an indication of the rank or wealth of the owner for whom it was made. The fibula is constructed of both solid and sheet elements riveted together: for example, the three onion-shaped terminals are hollow and are riveted to the main body, upon which are attached solid C-shaped volutes. The primary upper surfaces are decorated with similar repeating designs of arcs within circles, but each section is executed in a different silver inlay technique.

Reportedly from the vicinity of Trier, the Provincial Roman capital of the Rhineland, this fibula can be related in type and technique to others found throughout the Late Roman world. In addition, it complements a small group of crossbow fibulae made of copper alloy or gold in the collections of the Greek and Roman Art department as well as the Medieval Art department at the Metropolitan Museum.
