The Byzantine art can also be called the Christian art of East, between 4th century in which arose and 14th century in which the sunset began. In the 6th century the true grandiose of the arts was created by the Byzantine. This art maintained these classic traditions for various centuries and the renaissance of 10th and 14th centuries has had above all the persistence and the awakening of the ancient spirit. In the second half of the 13th century, we assist to the decline of the Empire of East, the advance of the invasion of Muslims and the separation from the Byzantine influence. The western culture is based on the reason of divine origin. The art, beyond the allegorical meaning, becomes technically constructive. The artist today difficultly succeeds to make a face human, an expression of the man-God. We are in full industrial age, from which we achieve egoism. Over the dogmatic contrasts between the two churches, the union is felt in spirit, and also in the spirit of art. The historical schism does not have the total force to separate; the re-unification of the Christian world is an aspiration of all the Europeans today.
