Pergamon
Pergamon's other notable structure is the great temple of the Egyptian gods Isis and/or Serapis, known today as the "Red Basilica" (or "Kızıl Avlu" in Turkish), about south of the Acropolis at (39 7' 19" N, 27 11' 1" E). It consists of a main building and two round towers within an enormous "temenos" or sacred area. The temple towers flanking the main building had courtyards with pools used for ablutions at each end, flanked by stoas on three sides. The forecourt of the Temple of Isis/Sarapis is still supported by the Pergamon Bridge, the largest bridge substruction of antiquity.
Telephus
Telephus was considered to be the mythical founder of Pergamon, as well as the ancestor of the Attalids, Pergamon’s ruling dynasty (from 241 BC). As early as a Milesian inscription (after 129 BC), the people of Pergamon were called Telephidai, descendants of Telephus. According to Pausanias, the Pergamon people claimed to be descendants of the Arcadians who had come with Telephus to Mysia. Inscriptions record the association between Pergamon and Tegea, and the most important cult of Pergamon, the cult of Athena, was said to have been brought from Tegea, and established at Pergamon by Auge.
