I found a book today called Men and the Fields by Adrian Bell, published in 1939, with lithographs by Paul Nash's younger brother, John. These illustrations may not have the visionary genius of Nash Major, but they are an important relic of a movement that included the wonderful Eric Ravilious and Edward Bawden.
These artists reclaimed the English countryside from the platitudes of lesser artists and their vision of the pastoral is a more challenging one, imbued with a mysticism that harkens back to William Blake.
On the subject of platitudes, that's enough amateur art criticism from me. Enjoy John Nash:
