在文学史上，《与元微之书》是一篇极具代表性的书信作品，它出自唐代著名诗人白居易之手。这篇书信不仅是白居易与好友元稹之间深厚友谊的见证，也是唐代文人交流思想、抒发情感的重要载体。

原文如下：

微之足下：自别以来，忽忽已过数月。常念足下才高德厚，令人钦慕不已。近闻足下新作诗篇，读来令人神往。然吾亦有小诗一首，附于信后，望足下笑纳。

今春以来，天气渐暖，百花齐放，景色宜人。吾每日闲暇之余，或游园赏花，或伏案读书，生活倒也安逸。然每逢夜深人静，思念足下之情便油然而生。不知足下近况如何？愿得一书以慰相思。

翻译如下：

Dear My Micro,

Since our last parting, time has passed swiftly, and several months have gone by. I often think of your great talent and noble character, which make me admire you deeply. Recently, I heard that you have written some new poems, and reading them made me long for more. However, I also composed a short poem, which I enclose with this letter, hoping you will accept it with a smile.

This spring, the weather has become warmer, flowers are blooming everywhere, and the scenery is pleasant. In my spare time, I either stroll in the garden to enjoy the blossoms or sit at my desk reading books, leading a rather peaceful life. Nevertheless, whenever I am alone late at night, thoughts of you arise spontaneously. I wonder how you are doing recently? I hope to receive a letter from you to ease my longing.

以上便是《与元微之书》的原文及其翻译。通过这封书信，我们可以感受到白居易对友人的深切关怀以及他们之间真挚的情谊。同时，这也反映了唐代文人之间频繁的文化交流和情感互动。
