Braganza Brooch in the context of "Fibula (brooch)"

A fibula (/ˈfɪbjʊlə/, pl.: fibulae /ˈfɪbjʊli/) is a brooch or pin for fastening garments, typically at the right shoulder. The fibula developed in a variety of shapes, but all were based on the safety-pin principle. Unlike most modern brooches, fibulae were not only decorative; they originally served a practical function: to fasten clothing for both sexes, such as dresses and cloaks.

In English, "fibula" is a word not used for modern jewellery, but by archaeologists, who also use "brooch", especially for types other than the ancient "safety pin" types, and for types from the British Isles. For Continental archaeologists, all metal jewellery clothes-fasteners are usually "fibulae".
