Per Amica Silentia Lunae

Collection of poetry and prose, first published in 1918. According to Wikipedia: "William Butler Yeats (play /ˈjeɪts/; 13 June 1865 – 28 January 1939) was an Irish poet and playwright, and one of the foremost figures of 20th century literature. A pillar of both the Irish and British literary establishments, in his later years Yeats served as an Irish Senator for two terms. He was a driving force behind the Irish Literary Revival and, along with Lady Gregory, Edward Martyn, and others, founded the Abbey Theatre, where he served as its chief during its early years. In 1923 he was awarded the Nobel Prize in Literature for what the Nobel Committee described as "inspired poetry, which in a highly artistic form gives expression to the spirit of a whole nation." He was the first Irishman so honoured."
