Photocopies of forty letters, 1947-1948, 1951-1960 and undated, from John Cowper Powys to Jill Olson and one photocopied letter, 1947, to Jill Olson's father, Powys's close friend Bernard O'Neill (f. 1), together with a photocopy of an enclosed printed publication notice for Powys's literary study of Rabelais (1948) (f. 8-verso). The letters to Jill Olson contain references to the deaths in 1947 of Bernard O'Neill and of Powys's sister-in-law Elizabeth Powys (née Myers) and to the onset and progression of the neural disease which afflicted Powys's son Littleton Alfred, leading to his death in 1954, while the letter to Bernard O'Neill mentions the latter's failing health and that Powys had begun the final chapters of "my Romance of the Dark Ages" (i.e. his novel Porius, published in 1951).
