In 2009, poet and scholar-at-large Grevel Lindop published two previously-unknown letters from Robert Cochrane (1931-1966), father of the modern Old Craft movement, to poet Robert Graves (1895-1985), whose book The White Goddess had been seminal (to say the very least) to Cochrane's thinking.
The first of these letters, unfortunately undated, begins:
I have read and re-read your book, 'The White Goddess,' with admiration, utter amazement and a taint of horror. I can see your point when you write of inspirational work, and realize that it must have resulted from quite an internal 'pressure,' since from my own experience, that is the way she works. However, I am just pointing out some other factors that might interest you in the manifestation of the 'Guiden Corn' (Lindop 6).
