About Penannular brooches: The Celtic brooch, more properly called the penannular brooch, is a type of clothes fastener. They are especially associated with the beginning of the Early Medieval period in Ireland and Britain. Beginning as utilitarian fasteners in the Iron Age and Roman period, they are especially associated with the highly ornate brooches produced in precious metal for the elites of Ireland and Scotland from about 700 to 900. Penannular brooches feature a long pin attached by its head to a ring. The pin can move freely around the ring as far as the terminals, which are close together. The penannular brooch is a simple and efficient way of fastening loosely woven cloth (where the pin will not leave a permanent hole).
