Gabriele D'Annunzio: Defiant Archangel by John Woodhouse (1998)
This one I picked up in a tiny rural Scottish bookshop when loitering over there and read on holiday. I had read some of his books, like The Flame, and dug them as they were so OTT. Have a penchant for "decedent" writers, but didn't know much about his life beyond what Wikipedia serves up. This is one of those "if someone made it up, you still wouldn't believe it" life stories. In a way, he reminds me of Aleister Crowley. You just think he must have been operating in a different dimension of time to pack that much into his life: write countless novels, plays and operas / seduce countless women / invade and rule a city / take part in several wars / have a raging coke addiction / be an elected politician / invent Italian fascism - all while being constantly broke and hustling to make ends meet for large periods of his life, through spending money he did not have and behaving like - what the English would term - a total "cad"; getting what he wants and not caring what wreckage he leaves behind: ex-wives, children, starving dogs etc. Reading it really makes you put your own life in perspective. I'm a busy guy who does not like to sit still, but I seem a lifeless blob compared to this dude! I believe this was the first biography written of him in English, and it's very well researched and written, detail-packed, bordering on hostile to anyone with a short attention span. The only flaw for me is that it spends two-thirds of the book covering the years up to the First World War, then gets briefer over the remaining periods of his life (he died in 1938). There is very little about post-Fiume, the city-state he set up in 1919. This is the period where his tastes got more and more debauched and outrageous, and Mussolini rose to power. Seek and engulf your mind in cold flames.
