One of the things that really strikes me reading this (and other writings from maybe around the 50's to the 70's) is how different the vocabulary and context for talking about fantasy were. The interviewer really seems to be struggling to convey the effect of 'secondary reality': 'long epic fairy tale', 'convoluted giant labyrinth', 'bizarre', 'alien and fascinating [beings]', and my favourite 'portrayed with . . . hallucinatory clarity'. It's like the only way the interviewer felt he could convey the story was through a mishmash of the Brothers Grimm, 'weird tales', and a drug trip. Nowadays he might just say 'fantasy' and save himself a lot of words.
It is hard indeed to believe that one of so great wisdom, and of powerfor many wonderful things he did among uscould perish, and so much lore be taken from the world.
