“Asklepios was more closely associated with the serpent. The Hellenic religious spirit represented the god as a dignified human figure, very similar in type to Zeus, supporting his right hand on a staff round which a serpent is twined. His serpent nature clings to him, though only as an attribute and adjunct, in the fully Hellenised form. In the Anatolian ritual the god was the Asklepian serpent, rather than the human Asklepios. Thus in Figure 23 the Emperor Caracalla, during his visit to Pergamum, is represented as adoring the Pergamenian deity, a serpent wreathed round the sacred tree. Between the God-Serpent and the God-Emperor stands the little figure of Telesphorus, the Consummator, a peculiarly Pergamenian conception closely connected with Asklepios.”
