This may not be the prettiest of Roman brooches, but from an archaeological perspective, it is very interesting. Timeless Galleries are pleased to offer a lovely 1st - 2nd century A.D. Roman Fibula Brooch.
The brooch represents a failed cast from nearly 2000 years ago. On inspection, one can clearly see the casting sprues which would have been filed away had the casting process been a success (in this case, it looks like the molten bronze failed to fully fill the mould.)
in fact, it is the total lack of sprues and casting lines which is a key indicator of authenticity for Roman fibula brooches. Modern replicas often display, upon magnification, evidence of filemarks and sanding where sprues and casting lines have been removed - something you will never see on an authentic Roman brooch. Metalsmiths of the Roman period were simply much better at their craft than us!
An interesting piece, now available at the Timeless Galleries
