Re: Zen in the art of archery
To get your feet wet on these four periods I mentioned, you could start with:
1. Dumoulin (his historical survey of Ch'an and Zen)
3. Brian Victoria "Zen at War"
4. and Doumoulin's survey of Zen in the 20th century
In these works you will get some sense of the major thinkers per each period as well as some general or broader historical context.
Hope that helps a bit - as you know, check the bibiliographies at the end of these works. These guys all read a lot. :-)
