原文（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.

翻译（当你老了）

当你年老，发丝灰白，睡意沉沉，

在炉火旁打盹，请取下这本书，

慢慢阅读，梦见你昔日柔和的目光，

以及它们深处的阴影；

多少人曾爱你青春欢畅的时辰，

爱你的美丽，假意或真心，

但只有一人爱你那朝圣者的灵魂，

爱你那日渐沧桑的脸上的哀伤；

在炉火边俯身，带着些许悲伤，

低声诉说，爱情已悄然离去，

它在头顶的群山间徘徊，

藏匿于繁星之中。

这篇译文试图捕捉原诗的情感深度和韵律美感，希望读者能感受到诗人对爱情的执着与真挚。
