A Viking period bronze ,,Omega" brooch, dating C. 9th-11th century A.D. The “Omega“ brooch is so called because it resembles the Greek letter. A penannular brooch featuring two trapezoidal plate finials, each with an engraved design. The brooch features a free-moving pin, which sits vertically across the length of the brooch. The pin is attached via a loop to the penannular hoop. The brooch features flat, unworked reverses. Has an emerald green and blue patina. A similar brooch found in Norfolk, Great Britain is illustrated in Hattatt's “Ancient Brooches,” figure 1688. The fibula was in widespread use throughout the ancient world. Roman conquests spread the use of the fibula, which became the basis for more complicated brooches. In the severe climate of northern Europe, it routinely functioned as a fastening for a heavy cloak or tunic. The safety-pin type of fibula continued to be used up into the Middle Ages, serving both as decorative and functional elements.
