I recently found a Wikipedia page about a supposed sect of Jews in first century Alexandria called the Therapeutae. According to various pages, they lived as monks, isolating themselves and studying Torah and their own special writings. Some sources say the Nazirites were a subset of Therapeutae (although this in particular seems like a stretch).
There's one problem: I have not been able to find a single Jewish source that mentions the Therapeutae. I don't know what, if anything, they were called in Hebrew. Is this just a myth?
Who were the Therapeutae? What, if anything, were they called in Hebrew? What was their relationship to the Nazirites? What do we know about them from our own sources?(Are they mentioned anywhere in Talmud or other traditional texts?)
