In an ancient sanctuary, many deities were given inscribed offerings. In the case of the Asclepieion of Pergamon, the good state of preservation of the site allows for an approximate reconstruction of the original place of exposition of these artefacts. Thus, it becomes possible to analyse how the dedications for various deities were disseminated through the sanctuary and shared the same space. This case study reveals the existence of links between the dedicatee of an inscribed offering, the ritual act behind it, and the materiality and place of exposition of the piece. To reach this conclusion, the specific cases of the bronze ex-voto and of the stone altars are analysed in more detail.
