The Fibula
The fibula is an everyday cloak clasp used in the same was as a baby pin is
used today. They were very common among all people in ancient times. Since the
fibula is so commonly found in archaeological sites, many originals in excellent
condition are available. The fibula is one item the style of which can be dated
to within ten years of its creation in some cases, allowing fibula finds to be
instrumental in dating other objects found at a particular site. The pins were
replaced with an alloy of bronze similar to that of the fibula, which is springy
and strong. There are thousands of fibula styles found in every country
throughout the British Isles, north Africa, Europe and the Mediterranean. The
fibula on the bottom right shows traces of tin which originally coated the
entire piece. Tin was often applied to protect bronze and brass from corrosion
and as decoration. The fittings of gladius and other sword sheathes, balteus
plates, and apron terminals were commonly tinned. Many household items were also
tinned. Often, selected areas of tin were removed to reveal the bronze
underneath to create artistic effects or to enhance engraved images.
