The Therapeutae were a religious sect which existed in Alexandria and other parts of the ancient Greek world. The primary source concerning the Therapeutae is the De vita contemplativa ("The Contemplative Life"), traditionally ascribed to the Jewish philosopher Philo of Alexandria (c. 20 BCE – 50 CE). The author appears to have been personally acquainted with them. The author describes the Therapeutae as "philosophers" (cf. I.2) and mentions a group that lived on a low hill by the Lake Mareotis close to Alexandria in circumstances resembling lavrite life (cf. III.22). They were "the best" of a kind given to "perfect goodness" that "exists in many places in the inhabited world" (cf. III.21). The author was unsure of the origin of the name and derives the name Therapeutae/Therapeutides from Greek θεραπεύω in the sense of "cure" or "worship" (cf. I.2). Philo's description of the doctrines and practices of the Therapeutae leaves great ambiguity about what religion they are associated with. Analysis by religious scholar Ullrich R. Kleinhempel indicates that the most likely religion the Therapeutae practiced was Buddhism. Name The term Therapeutae (plural) is Latin, from Philo's 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 word "Therapeutae" may also have been adapted from the Indian Pali word for traditional Buddhists, Theravada. De vita contemplativa account Philo described the Therapeutae in De vita contemplativa ("On the contemplative life"), written in the first century CE. The origins of the Therapeutae were unclear, and Philo was even unsure about the etymology of their name, which he explained as meaning either physicians of souls or servants of God. The opening phrases of his essay establish that it followed one that has been lost, on the active life. Philo was employing the familiar polarity in Hellenic philosophy between the active and the contemplative life, exemplifying the active life by the Essenes, another severely ascetic sect, and the contemplative life by the desert-dwelling Therapeutae. According to De Vita Contemplativa, the
