Technical Observations: The patina consists of pale green and brown corrosion with a few areas of bare metal. The fibula is intact. The body was cast, probably by the lost-wax process, with the surface designs created in the wax model. The pin was made separately by hammering and attached to the body of the fibula by a thin rod that seems to have been inserted in one end of the crossbar. This inner pin may have been iron, since iron corrosion products are visible, but it is no longer magnetic. The surface shows rough finishing marks.
