Meanwhile, the 8th and 7th centuries BC saw the introduction of the so-called Phrygian bow fibulae in Asia Minor. These fibulae had a near-perfect semi-circular arch sometimes decorated with knobs or round flanges. In the same period, the Hand or Arm fibula spread from Cyprus, where it appears to have originated, to Syria, Assyria and Persia. In this design the bow was bent 90 degrees at the apex giving the fibula a triangular shape when viewed from the side. The bow was usually decorated with a series of rings and dots. The catch plate usually had the form of a hand, making the entire fibula resemble an arm.
