Romanesque art, developed between the 11th and 13th centuries, is conceived as a theological language rather than a naturalistic one. Its purpose is to convey divine omnipresence and authority through iconography inspired by the Book of Revelation: the Pantocrator surrounded by the tetramorph (lion, ox, eagle, and man), seraphim with wings full of eyes, and the Lamb of God with seven eyes—symbols of vigilance and judgment. This visual program reinforces the doctrinal function of medieval art. In the apse of Sant Climent de Taüll (Vall de Boí), a masterpiece of Catalan Romanesque art, the Dextera Domini (God’s right hand) appears inscribed in a mandorla on the triumphal arch, symbolizing divine power and protection. This motif responds to the biblical prohibition against depicting God in full, showing only his intervention. Painted with high-quality pigments (cinnabar over hematite), it demonstrates the technical and conceptual sophistication of the anonymous workshop that executed the cycle around 1023. The ensemble combines biblical visions (Revelation, Isaiah, Ezekiel) to represent the Last Judgment, making it one of the most significant examples of Romanesque art in Europe.
