I have completed the chiastic structure of each pericope for the entire gospel and updated all my previous work. This laying out of Mark has paid dividends in my understanding of the author's original intention, and highlighted interpolations, redactions, and other text-critical issues. It has also shown the reason for many odd Markan habits, such as his doublets and duplications, and other puzzling features of Mark. In many cases these features signal the beginning of brackets.
To see the entire gospel laid out chiastically, with my comments on the side, go here. The page contains two large .jpg files -- the only way I could make sure it loaded up properly in each type of browser -- with my comments.
For the rules used in constructing these chiasms, please see the previous post here. There's still quite a bit of tinkering left, and I'll make a note of final adjustments and further comments on this site.
