Thomas William Hazen Rolleston (1857 – 1920) was an Irish writer, literary figure and translator, known as a poet but publishing over a wide range of literary and political topics. He lived at various times in Dublin, Germany, London and County Wicklow; settling finally in 1908 in Hampstead, London, where he died. He was born in Glasshouse, Shinrone, County Offaly, the son of a judge. He was educated at St Columba's College, Rathfarnham and Trinity College, Dublin. After a time in Germany he founded the Dublin University Review in 1885; he published Poems and Ballads of Young Ireland (1888), and a Life of Lessing (1889). In London in the 1890s he was one of the Rhymer's Club; he was to cross paths several times, and sometimes to clash, with W. B. Yeats. He was also involved in Douglas Hyde's Gaelic League. He also spent time as a journalist, and as a civil servant involved with agriculture. He had eight children, from two marriages. His seminal works "Celtic Myths and Legends" and "The High Deeds of Finn Mac Cumhail" are widely hailed as the best representation and description of all the legends, myths and spiritual history of all Celtic peoples of Ireland, Britain, and Wales. Approximately 168 books are associated with Rolleston, some as writer or editor. These are the more prominent works; publication dates listed if known.
