William Butler Yeats is widely considered to be one of the greatest poets of the 20th century. He belonged to the Protestant, Anglo-Irish minority that had controlled the economic, political, social, and cultural life of Ireland since at least the end of the 17th century. Most members of this minority considered themselves English people who happened to have been born in Ireland, but Yeats staunchly affirmed his Irish nationality. Although he lived in London for 14 years of his childhood (and kept a permanent home there during the first half of his adult life), Yeats maintained his cultural roots, featuring Irish legends and heroes in many of his poems and plays. He was equally firm in adhering to his self-image as an artist. This conviction led many to accuse him of elitism, but it also unquestionably contributed to his greatness. As fellow poet W.H. Auden noted in a 1948 Kenyon Review essay entitled “Yeats as an Example,” Yeats accepted the modern necessity of having to make a lonely and deliberate “choice of the principles and presuppositions in terms of which [made] sense of his experience.” Auden assigned Yeats the high praise of having written “some of the most beautiful poetry” of modern times. Perhaps no other poet stood to represent a people and country as poignantly as Yeats, both during and after his life, and his poetry is widely read today across the English-speaking world.

When You Are Old 

When you are old and grey and full of sleep,
And nodding by the fire, take down this book,
And slowly read, and dream of the soft look
Your eyes had once, and of their shadows deep;

How many loved your moments of glad grace,
And loved your beauty with love false or true,
But one man loved the pilgrim soul in you,
And loved the sorrows of your changing face;

And bending down beside the glowing bars,
Murmur, a little sadly, how Love fled
And paced upon the mountains overhead
And hid his face amid a crowd of stars.
