Ex voto of the Attalids
Greece
Several Hellenistic kings dedicated monuments in the sanctuary of Apollo in Delphi, in an effort to emphasize their prestige. Among those kings were the Attalids of Pergamon, who occupied a prominent position at the highest point of the Sacred Way, close to the temple of Apollo where they erected their ex votos.
