These unusual objects are known as 'crotals' - globular or pear-shaped bells or rattles. They may have been rather heavy for suspension from straps, for example on horse harnesses, and instead may have hung from a rigid support, such as the draught-pole of a wagon. In this way the sound produced while in motion, while not very 'musical', would nevertheless draw attention to and enhance the procession of the wagon. As wagon accessories, crotals join other ornamental bronzes in embellishing wheeled vehicles in this period.
