Celibacy and asceticism - everything from monastic orders to fasting. Having no background on the topic, I need suggestions for which books (and/or movies) to read:

1. So, please give me a list of several (so that I find one or two at least in my area) books or articles or links that are 'essential' to my topic and are also fairly short.

2. Information on a movie that that deals with the priesthood and celibacy--the name is something like 'in the name of roses.' Do you know which movie I am talking about?

3. Information on a book by Aristotle or some philosopher, which was not supposed to be read by priests; whoever read it ended up dying. But in the end, they found out that there was a poison on the papers of book. If you know the title of this movie or know some links to search, please let me know.
