What is "globus cruciger"

n. A globe topped by a cross: used as a symbol of royal power.

The globus cruciger ( Latin, "cross-bearing orb"), also known as the orb and cross, an orb (Latin globus) topped (Latin gerere, to wear) by a cross (Latin crux), has been a Christian symbol of authority since the Middle Ages, used on coins, in iconography, and with the sceptre as royal regalia. The cross represents Christ's dominion over the orb of the world, literally held in the hand of an earthly ruler (or sometimes it is held by an angel). In the iconography of Western art, when Christ himself holds the globe, he is called Salvator Mundi, the Saviour of the World; his statue is the Infant Jesus of Prague.
