"The Sweet Science" A.J Liebling book.

Arab and Nemesis (on Rocky Marciano-Archie Moore) is his Mona Lisa.

A short except:

When the principals shook hands, I could see Mr. Moore’s eyebrows like storm clouds over the Sea of Azov. His whiskers bristled and his eyes glowed like dark coals as he scrunched his eyebrows down again and enveloped the Whale with the Look, which was intended to dominate his will power. Mr. Wilson and I were sitting behind Marciano’s corner, and as the champion came back to it I observed his expression, to determine what effect the Look had had upon him. More than ever, he resembled a Great Dane who has heard the word ‘bone.’

One more, describing when Moore knocked Marciano down:

So Ahab had his harpoon in the Whale. He had hit him right if ever I saw a boxer hit right, with a classic brevity and conciseness. Marciano stayed down for two seconds. I do not know what took place in Mr. Moore’s breast when he saw him get up. He may have felt, for the moment, like Don Giovanni when the Commendatore’s statue grabbed at him — startled because he thought he had killed the guy already — or like Ahab when he saw the Whale take down Fedallah, harpoons and all. Anyway, he hesitated a couple of seconds, and that was reasonable. A man who took nine to come up after a punch like that would be doing well, and the correct tactic would be to go straight in and finish him. But a fellow who came up on two was strong enough that he would bear investigation.
