This is probably one of the most famous poem from Yeats. The themes of the poem are love, loss and regret and although based on the poet’s own personal life, the sentiment reflected in this poem is common to most, if not all, rejected lovers.

The speaker of the poem addresses his beloved saying that when she is aged she should read a particular book which will remind her of her youth. She will remember the people who had loved her grace and her beauty with either real or fake sentiments in the past, and also that one man who had loved her soul unconditionally as she grew old and the way she looked changed. As she is reminded of him, she will regret her missed opportunity of true love.

When You Are Old

W. B. Yeats, 1865 - 1939

 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.\
