The first fibulae design, violin bow fibulae ("drahtbugel" in German), appeared in the late Bronze Age. This simple design, with a unilateral spring, looks remarkably like a modern safety pin. The violin bow fibula has a low flat arch; the body runs parallel to the pin so it resembles a violin bow. The bow could be round, square, or flat and ribbon-like in cross-section. Some had simple punched or incised decoration on the bow. Violin bow fibula, such as the Peschiera type and the Unter-Radl type, was introduced in the 14th century BC (Late Mycenean III era) by the Myceneans on the Greek Peloponnesus. The fibula soon spread to Crete, Cyprus and Mycenean trading posts in Sicily.
