I'm doing a "reliability of the text" study and want to review the reliability of the texts that have been used to substantiate the Miyamoto Musashi texts The Book of the Five Rings and The Path of Aloneness. I've already been through all of the websites on the internet (alright, not all of them), and whilst I've found lots of "facts" about the books and the like, I can't find a single scholarly article or reference to archaeology supporting his existence or that justifies that he actually wrote what we have in our hands today.
In particular, things I'm looking for are:
- Datings for the manuscripts
- Number of concordant manuscripts
- Considerations of differences between the published popular works and the originals.
I've been unable to find anything and would appreciate some help.
