A Fibula is an ancient brooch. (Plural: fibulae). Technically, the latin term fibulae meant Roman brooches, but the term is widely used for brooches from the entire ancient and early medieval world. Unlike modern brooches, fibulae were not only decorative, they originally served a practical function: to fasten clothes, including cloaks. Fibulae replaced straight pins that were used to fasten clothing in the Neolithic period and Bronze Age. In turn, fibulae were replaced as clothing fasteners in the Middle Ages by buttons. Their descendent, the modern safety pin, remains in use today.
