Charles Sprawson is, apparently, an obsessive swimmer who (like Byron) once swam the Hellespont and this is a very engaging study of swimming, and swimming heroes, in different cultures. From the English/classical/public school tradition, imbued with the glory that was Greece and Rome and more than a dollop of homo-eroticism, through German Romanticism to - and this is the section I enjoyed most - swimming and the American dream. From Eakins' Arcadian swimming hole to Scott Fitzgerald's Gatsby and Dick Diver, Johnny Weissmuller, John Cheever's Swimmer, and Hockney's shimmering Californian pools.
One slightly annoying flaw, however, is the author's habit of citing notable swimmers by their surnames only - even at first reference - and often without even the briefest explanation of who they are. Several times I found myself asking, 'Who he?' Surely an editor should have picked up on this? It sometimes felt like he was talking about a coterie of old schoolfriends to whom I hadn't been introduced.
