Tomás Ó Criomhthain (1856–1937) is not just an Irishman and, as a result, an islander, but an islander twice: a native of the Great Blasket Island, located about two kilometers from the village of Dong Hung on the western tip of the Dangyang Peninsula (Dingle) in County Kerry - the westernmost point of Ireland and Europe. Life on the Blasket Islands did not change, no matter how turbulent European history was, and the islanders adhered to everyday traditions, and also kept the Irish language without any changes - and without any effort: they just lived like that. At the very beginning of the 20th century, at the height of the Irish Renaissance, a visitor to the island persuaded O'Crihin to compile a detailed chronicle of everyday life on Blasket. The result of their five-year correspondence is one of the key documents of modern Irish-language literature and its inspiration for the entire twentieth century, a language museum, an amazing cultural artifact and a whole special universe, irrevocably left in the past.
