(Lat. mundus) is a term in heraldry, designating a globe surmounted with a cross (generally) pattee. As a device, it is said to have been used by the emperor Justinian, and to have been intended to represent the ascendency of Christianity over the world. The royal crown of England is surmounted by a mound, which first appears on the seal of William the Conqueror, though the globe without the cross was used earlier.
