Аннотация:The research subject is the representation of the image of the Lord in the iconographic program of the apse mosaic of the oratory of abbot Theodulf at Germigny-des-Prés. The research object is the iconographic program of the apse of the oratory at Germigny-des-Prés. The author of the program, abbot Theodulf, was the abbot of Fleury-sur-Loire, a poet, a theologian and the closest fellow of Charles the Great. His aniconic ideas played an important role in defining the way of representing the Divine Presence within the space of the church he had built. Based on the method of iconographic analysis, the author analyzes the Old Testament images of Theodulf’s mosaic and compares them with the Holy Writ. The article considers the modern ideas about the disputable iconographic program of the apse mosaic of the oratory and offers another variant of interpreting Theodulf’s program that supplements the existing interpretations. The author shows that the unseen by a human eye Glory of the Lord surrounded by cherubs is the key object of the program and a part of the composition, which symbolically means also the beginning of the Eucharistic canon.
