Therapeutae of Asclepius
Therapeutae (plural) is Latin from the Greek plural "Therapeutai" (Θεραπευταί). The term "therapeutes" means one who is attendant to the gods although the term, and the related adjective "therapeutikos" carry in later texts the meaning of attending to heal, or treating in a spiritual or medical sense. The Greek feminine plural "Therapeutrides" (Θεραπευτρίδες) is sometimes encountered for their female members. The term therapeutae may occur in relation to followers of Asclepius at Pergamon, and "therapeutai" may also occur in relation to worshippers of Sarapis in inscriptions, such as on Delos. The therapeutae of Asclepius were a recognized  and designated association in antiquity that included the physicians, their attendants and support staff, in the larger temples of Asclepius. These healing temples were known as Asclepeions. Examples of famous therapeutae of Asclepius between 300 BCE and 300 CE include Hippocrates, Apollonius of Tyana, Aelius Aristides and Galen. The Greek word has the primary meaning of 'one who serves the gods, or 'worshipper'. Aelius Aristides in the later 2nd century writes: ""We Asclepius therapeutae must agree with the god that Pergamum is the best of his sanctuaries."" - Sacred Tales (39.5) Galen used his designation of "therapeutae" to secure from the  Roman Emperor Marcus Aurelius exemption from military service. In their book "Voluntary Associations in the Graeco-Roman World" the authors state: "Some therapeutae are known to have rented apartments within the sanctuary in order to be close to the deity" (Apileius, Met, 11.19.1). "Very little is known about the purpose of the therapeutae. Vidman thinks they were simple worshipers united in a loose association (1970:69, 125-38). "cf. therapeutae of Asclepius at Perganon" (Habicht 1969: 114-115)" The following authors (in their books) make reference to the therapeutae:
