Ave n0x,
Because you find the technical aspects of
brooches more interesting than the design here is one
that you may truly appreciate. I have shared this
brooch before, but as you are new here...?
Pannonian
Anchor Fibula with bird decoration on the bow. ca. 100-175 AD
Copper
alloy; 48mm/34.3gm
In later examples, the bird decorations are often
stylized or degenerated. Mine is obviously an early and high
quality example with a very realistic bird. The knobs at the end of the
spring cover (which are meant to cover the rivets that hold the cover in place) are just abstract, or perhaps puppy dogs? By my count there are at least 14 at least different
cast parts before all were assembled to create this
fibula.
I
hope this helps you with your collecting interest.
Best regards,
Kevinj
