Since the Bronze Age when the Romans first began shoeing their horses, the horseshoe has been a symbol of good fortune. Horseshoes have hung above doorways ever since. There is some debate as to proper positioning of a horseshoe. Some believe that the tips of the shoe should point up so that the good luck is retained and that if the horseshoe points down the good luck will be lost. Others believe that the tips of the shoe should point down spilling good luck onto all who pass beneath.
Besides luck, the shape of the horseshoe is pleasing and graceful in its appearance. It is known that shapes generate psychological responses from people. The use of shapes to convey, associate, communicate or reflect meaning has been evident throughout history.
