SUMMARY
The basilical complex of S. Prassede, commissioned by Paschal I (817-824) at the beginning of his papacy, houses one of the most important frescoe cycles of early medieval Rome, which, together with the architecture and mosaics of this same basilica, turn it into a privileged monument for the study of the artistic production of the early ninth century. This paper proposes a first approach to these so far barely explored frescoes, and a state-of-the-art review of another complex linked to Paschal I, S. Cecilia in Trastevere, and more specifically of the decoration of its baptistery. This research is part of a more ambitious project aimed at deepening our understanding of Rome in times of Paschal I on the occasion of the 1200th anniversary of his elevation as pope.
