On an Irish Island is a love letter to a vanished way of life, in which Robert Kanigel, the highly praised author of The Man Who Knew Infinity and The One Best Way, tells the story of the Great Blasket, a wildly beautiful island off the west coast of Ireland, renowned during the early twentieth century for the rich communal life of its residents and the unadulterated Irish they spoke. With the Irish language vanishing all through the rest of Ireland, the Great Blasket became a magnet for scholars and writers drawn there during the Gaelic renaissance—and the scene for a memorable clash of cultures between modern life and an older, sometimes sweeter world slipping away.

Kanigel introduces us to the playwright John Millington Synge, some of whose characters in The Playboy of the Western World, were inspired by his time on the island; Carl Marstrander, a Norwegian linguist who gave his place on Norway’s Olympic team for a summer on the Blasket; Marie-Louise Sjoestedt, a Celtic studies scholar fresh from the Sorbonne; and central to the story, George Thomson, a British classicist whose involvement with the island and its people we follow from his first visit as a twenty-year-old to the end of his life.
