This book explores the confluence of Late Antique literature and visual culture in the Kingdom of Asturias, focusing on the artistic trends of the reign of Alfonso II (791-842). The research is focused on the content of the literary works available to the chroniclers of Alfonso III, who wrote their works forty years after the death of Alfonso II, in particular on the use of the Latin version that Rufinus of Aquileia (c. 403) made of Eusebius of Caesarea?s Historia Ecclesiastica, which preserves a narrative of the life of the first Christian emperor, Constantine I (306-337). All the visual evidences point to the emulation of the Constantinian ideal: the devotion and instrumentalisation of the Cross, the related liturgical feasts and the symbolic representation of the True Cross, through the use of the Constantinian vision?s motto in Oviedo, the parallelism between the inuentio Petri and the inuentio Iacobi, and even the similarity of the funeral arrangements of both Christian rulers. These testimonies strengthen the legitimation of the Kingdom of Asturias through a cultural memory, in which the idea of ??Rome and the Visigothic Kingdom of Toledo play a crucial role.
