Bayeux Tapestry (BT) depicts the Norman Conquest (1066). It is a typical example of Romanesque arts. In the 'Tapestry' with woolen embroidery on linen cloth, a variety of animals, plants, and human beings are depicted as well as the main story. They remind us of the sculptures at the capitals and friezes in the Romanesque churchs. This paper clarifys the cultural multiplicity in BT. BT was created as a result of contact between Normans and Anglo-Saxons. The theme is Norman, but the technique is famous Aglo-Saxon embroidery. In BT, present people try to find what really happened, but medieval people regarded all earthly happenings as divine scheme. Sanctity and laity were not yet separated. As a cleric, Odo bishop of Bayeux appears in the scenes; Williman decided to build the fleet for expedition, and to build Hastings castle, and Odo in the Battle of hatings to encourage young soldiers. As a God's servant, Odo cooperated with William to punish peifidious Harold to his death. Here we can see the cooperation between sanctity and laity. BT depicted the Norman Conquest of England. It was an example of interactions between different people and cultures. But, it was a story within the Christian world. The cultural multiplicity in BT is an interwoven layers of various cultural principles within one world viewpoint.
