In the eighth century, Byzantium, unlike the West, witnessed intense debates over the use of icons. While the Second Council of Nicaea (787) sought to resolve the controversy by affirming the veneration of icons after the absolute prohibition enacted by the Council of Hieria (754), the issue remained contentious and resurged intermittently. In the West, where icons did not hold the same theological significance as in the East, the matter gained attention when the decisions of the Second Council of Nicaea reached Charlemagne. This prompted significant theological engagement, particularly by Theodulf of Orl & eacute;ans, leading to the creation of the Libri Carolini. The Libri Carolini, a polemical work composed in response to accusations of icon worship during the Second Council of Nicaea, also criticized the earlier council's iconoclastic stance. Written from Charlemagne's perspective and comprising four books, the treatise reflects the Carolingian world's nuanced and moderate approach to the role of icons in Christian worship. This article examines the Libri Carolini's critique of icon veneration and its articulation of the Western perspective during Charlemagne's reign. It also seeks to illuminate the broader implications for East-West relations and the dynamics between imperial authority and the Church.
