The Monastery of St. Euthymios was a well known and influential monastery, primarily because of its role in the Chalcedonian christological controversy and its direct influence on the practice of monasticism. The coenobitic monastery grounds primarily consists of a series of caves in which the hermits spent their time. Within these caves are a series of wall paintings of various saints and holy people. In the present article, Andreas Mader presents a thorough study of these caves and the paintings they contain. Mader begins by discussing the topography of the Khirbet el-Mard region, which is the location of the monastery. He continues with a detailed description of the paintings, including a stencil drawing indicating the position of the figures represented in the paintings and several photographs of the paintings themselves. Mader concludes with a discussion of the influence of the Monastery of St. Euthymios on the development of monastic practices within early Christianity.
