 They are accompanied by a succinct commentary by Heinesen sufficient to string them together, but not such as in any way to turn this into a scholarly, academic edition of the letters.It is ultimately a deeply personal and poetical work, but nevertheless a work of vital importance to an understanding of Jacobsen and his sole novel.In his introduction, Heinesen makes it clear that this is only a small selection of letters, which in total fill some 1,500 pages, and that it is, strictly speaking, not an autobiography.
