shipping business. Soon after William's birth, the family relocated to the Pollexfen home at Merville, Sligo, to stay with her extended family, and the young poet came to think of the area as his childhood and spiritual home. Its landscape became, over time, both personally and symbolically, his "country of the heart". So too did its location by the sea; John Yeats stated that "by marriage with a Pollexfen, we have given a tongue to the sea cliffs". The Butler Yeats family were highly artistic; his brother Jack became an esteemed painter, while his sisters Elizabeth and Susan Mary—known to family and friends as Lollie and Lily—became involved in the Arts and Crafts movement. Yeats was raised a member of the Protestant Ascendancy, which was at the time undergoing a crisis of identity. While his family was broadly supportive of the changes Ireland was experiencing, the nationalist revival of the late 19th century directly disadvantaged his heritage and informed his outlook for the remainder of his life. In 1997, his biographer R. F. Foster observed that Napoleon's dictum that to understand the man you have to know what was happening in the world when he was twenty "is manifestly true of W.B.Y." Yeats's childhood and young adulthood were shadowed by the power-shift away from the minority Protestant Ascendancy. The 1880s saw the rise of Charles Stewart Parnell and the home rule movement; the 1890s saw the momentum of nationalism, while the Irish Catholics became prominent around the turn of the century. These developments had a profound effect on his poetry, and his subsequent explorations of Irish identity had a significant influence on the creation of his country's biography. In 1867, the family moved to England to aid their father, John, to further his career as an artist. At first, the Yeats children were educated at home. Their mother entertained them with stories and Irish folktales. John provided an erratic education in geography and chemistry and took William on natural history explorations of the nearby Slough countryside. On 26 January 1877, the young poet entered the Godolphin School, which he attended for four years. He did not distinguish himself academically, and an early school report describes his performance as "only fair. Perhaps better in Latin than in any other subject. Very poor in spelling". Though he had difficulty with mathematics and languages (possibly because he was tone deaf), he was fascinated
