The article illustrates the importance of the discovery in 2012 of Codex Monacensis Graecus 314, containing 29 homilies on the Psalms by Origen. It is not only one of the most important finds of early Christian literature in Greek in the last decades, but it is also a major contribution to the study of the Alexandrian teacher and to the history of biblical interpretation in Late Antiquity. The 29 homilies represent nowadays the largest body of sermons among the writings of Origen, which are poorly preserved in their original language. They also provide interesting clues for assigning the homilies to the final period in the life of Origen.
