The temples and healing centers built in the name of Asclepius, the god of health, in the Hellenistic Period are called "Asclepion". The caretaker and healing priests living in the houses built next to these places and believed to be descendants of Asclepius are called "Asclepiades". In this regard, while the most important healing center of the Classical World is Epidaurus in Greece, Pergamon Asclepion comes second.
