A large number of archaeological and epigraphic testimonia refer to statues of Attalid kings in the gymnasion of Pergamon. The various records and media have not yet been systematically correlated. This article aims to compile and describe the corpusof royal statues installed in the Pergamon gymnasion during the Hellenistic period, as well as to assess the function of these statues and their importance for royal representation in the gymnasion. Particular focus is on the relationship between royal statues and the ruler cult practiced in the gymnasion as well as how these statues were preserved and transformed until Late Antiquity. Visual integration and visual continuity seem to have played a major role in this process.
