During my youth & young adulthood, first T. S. Eliot and then W. H. Auden were the cynosures in my poetic sky, simply the best and greatest living poets in the English language, both exponents of Anglican spirituality, & both Anglo-Americans though moved in opposite directions. The elder Auden, the international transatlantic Goethe who wrote for the New Yorker & the NYRB was my senior contemporary. The young poet of the firm Auden, Spender & Isherwood, Poets belonged to the bypassed literary legendary of the Auden Generation, to postwar Berlin & the Spanish Civil War. I learned from this book that the real pre-1938 Auden was a little Englander, a rural nature poet fascinated by mining machinery. I did not read this book with a Kindle - the weighty hardback was a challenge and it took me the best part of a month to get through it. The best parts are the close readings of particular poems which the author sees as crucial to that stage in Auden's development: 'Who stands the crux left of the watershed', "Sir, no man's the enemy, forgiving all' (perhaps Auden's first religious poem), 'It was Easter when I walked in the public gardens' (the great Berlin poem), and especially 'Out on the lawn I lie in bed', inspired by Auden's first mystical experience. Jenkyns makes no attempt to be comprehensive (& the book is very long as it is) but I missed a discussion of some of my personal favourites, especially the 'Address for a Prize Day' & 'Letter to a Wound' - which along with Herod's speech in 'For the Time Being' are my choices for the finest (and funniest) prose poems in the language. 'Letter to a Wound' was a great consolation for me when recovering from serious surgery. This is also a book one reads like a scholar, with bookmarks in both the body of the text and the notes in the back. The biographic information on Auden's relationship with Michael Yates, the 15-year-old schoolboy who inspired 'Lay your sleeping head, my love', according the Richard Crossman the greatest homosexual love poem ever, was immensely illuminating and yet by contemporary #MeToo standards Auden the 20-something schoolmaster surely should be adjudged a predatory paedophile who belonged in gaol. (Auden's own first sexual experience with an adult was at 13 with the school chaplain - horresco referens.) One's tempted to say autres temps, autres moeurs & with cynics such as Evelyn Waugh & Simon Raven regard access to boys as then one of the few perks of an underpaid profession. I did find it revealing how much Auden was influenced by a crackpot psychologist such a Gerald Heard, though like me Auden was a Jungian. But whilst I didn't always agree with the author's insights, especially the psychologizing about the absence of Auden's father in the RAMC during the First World War and the effect of war remembrance on Auden's juvenilia (Jenkyns assumes that when a small animal does something unpleasant to another small animal, it's really an allusion the the Great War), I found this book utterly enthralling.
