Abstract/Hauptbeschreibung (Englisch)

Many passages from ancient literary sources notice the theoretical and practical training process requested for architects and engineers in Late Antiquity and Early Byzantium. In this paper, firstly we try to explain how Anthemius of Tralles and Isidore of Miletus the Elder, the famous architects of Saint Sofia in Constantinople, fully embody the pattern outlined by the sources. Furthermore, through the case of the two Isidores, we verify in which terms family relationships affect the transmission of technical and artisanal skills.
