Influence
Art was originally local, that is, confined to the community, but later was subjected to various influences—Political, Religious, and Commercial.
Political, by treaty or intermarriage, when imported taste or interchange would result, or by conquest.
Judging by the past, the conquered have invariably imposed their taste on their conquerors, as instanced in the Greek conquest of Persia; that of the Romans of the Greeks, and later the perpetuation of the Roman influence after their subjugation at the hands of the Goths.
The Crusades resulted in the importation of fabrics of Eastern and Sicilian origin, and may be classed as a religious influence; an earlier example of which may be cited in the edict of Pope Leo III in A.D. 726 in response to the iconoclastic movement, by reason of which the Byzantine art workers, deprived of their living, emigrated to the Rhine district.
