What is the X in X-mas?
bronze horn, or trumpet, found in prehistoric Scandinavian excavations. It has a conical bore that extends in length from roughly 5 to 8 feet (1.5 to 2.5 metres) in a bent S-shape (somewhat resembling a mammoth tusk) and ends in an embossed metal disk. The mouthpiece of the lur is permanently affixed. Lurs are usually found in pairs and were probably played ritually.
