Fibulae or brooches were originally used in Ancient Greece and in the Roman Empire for fastening garments, such as cloaks or togae. The fibula designs developed into a variety of shapes, but all were based on the safety-pin principle. The Roman’s conquests spread Roman culture and therefore the use of the fibula, which became the basis for more complicated and highly decorated brooches, modelled in bronze, silver and gold and further enriched with precious and semi-precious gemstones. Fibulae are the most common artefact-type in burials and settlements throughout much of the continental Europe. By the Middle Ages, the Roman safety pin type of fibula had fallen into disuse.
