A Moveable Feast by Ernest Hemingway:
Ezra wanted me to teach him to box and it was while we were sparring late one afternoon in his studio that I first met Wyndham Lewis. Ezra had not been boxing very long and I was embarrassed at having him work in front of anyone he knew, and I tried to make him look as good as possible. But it was not very good because he knew how to fence and I was still working to make his left into his boxing hand and move his left foot forward always and bring his right foot up parallel with it. It was just basic moves. I was never able to teach him to throw a left hook and to teach him to shorten his right was something for the future.
Wyndham Lewis wore a wide black hat, like a character in the quarter, and was dressed like someone out of La Bohème. He had a face that reminded me of a frog, not a bullfrog but just any frog, and Paris was too big a puddle for him. At that time we believed that any writer or painter could wear any clothes he owned and there was no official uniform for the artist; but Lewis wore the uniform of a prewar artist. It was embarrassing to see him and he watched superciliously while I slipped Ezra’s left leads or blocked them with an open right glove.
