History of insanity and criminality before the 19th century--a bleg

For a chapter in a book on the insanity defense, I'm doing a little research on the history of insanity as a phenomenon relevant to criminality. So far I've found plenty of discussion of 19th century developments. But what I'd really like are primary sources that predate the 18th and 19th centuries (setting to the side sources like Coke, Hale, and Blackstone) or secondary sources that discuss a discrete pre-19th century period. And in particular, if there are writings by Catholic thinkers related to the subject even tangentially, I'd very much like to read them. Any suggestions? [please write to me off line].
