For a comparatively small island, Ireland has made a disproportionatly large contribution to world literature in all its branches. Irish literature encompasses the Irish and English languages. The island's most widely-known literary works are undoubtedly in English. Particularly famous examples of such works are those of James Joyce, Oscar Wilde, and Ireland's four winners of the Nobel Prize for Literature; William Butler Yeats, George Bernard Shaw, Samuel Beckett and Seamus Heaney. Ireland's oldest literary traditions, however, are found in the Irish language, referred to simply as "Irish". Indeed, Irish has the third oldest literature in Europe (after Greek and Latin) and the most significant body of written literature (both ancient and recent) of any Celtic language. Furthermore, the historic influence of Irish language traditions, such as a strong oral tradition of legends and poetry, has helped make much English Literature in Ireland quite distinctive from that in other countries.
