This is a bow fibula and set of matching dress pins that I made on June 13th.  The bow fibula and matching dress pins were all hand-beaten from copper wire.  The style of the fibula is similar to simple bow fibulae made in Europe from approximately the 12th century BC up to the Roman era.  Fibula are not only supposed to be beautiful, but serve a functional purpose similar to a modern safety pin.

For a brief historic overview of fibulae, I found a forum article: Fibulae and ancient brooches
