The Byzantine Image Production and Practices. BARBU. The article first examines the "schism of images", i.e the moment when Carolingian Europe and Byzantium (mostly after the Triumph of Orthodoxy of 843) started on producing and practicing religious images according to different theological principles. The miracles set apart, to be looked at was perhaps the main function of the byzantine image, and at the same time, a procedure used by the Church authority in order to control the religious attitudes and conducts. Once related to the exercice of power, the production of images and the organization of the practices involved by the images is analyzed, in the last section of the paper, by means of two particular examples of the fourteenth century, from the St Nicholas Church of Curtea de Arges (Vallachia).
