He has done some interesting work in regards to these parallels between Hemingway's life and fiction. He pays particular attention to the injury Hemingway suffered at age eighteen when he served as an ambulance driver for the Italian army, and how and why this episode resurfaces in his literature. According to Young, the heroes are clothed in rituals, symbols, and legends. One local described him as being a hippie before there was such a thing, traipsing around openly in shorts, t-shirts and sandals. Well, it was the '30's.
Book looks worth reading.
I type Fitzgerald Inventive and Hemingway Artistic .
