《早秋》是唐代诗人许浑的五言律诗。此诗描绘初秋景色。前四句写早秋的夜景，五、六两句写早秋的昼景，在描绘秋景的过程中，诗人注重高低远近，落笔细致而层次井然。“一叶落而知天下秋”，最后两句运用《淮南子》与《楚辞》典故，浑然一体，神气十足，又将身世感叹暗寓于其中。

《早秋》 许浑

遥夜泛清瑟，西风生翠萝。
残萤栖玉露，早雁拂金河。
高树晓还密，远山晴更多。
淮南一叶下，自觉洞庭波。

Early Autumn
Xu Hun

The clear sound of zither hovers at night,
Among green vines rises the western breeze.
The last fireflies rest on the dew jade-white,
The Milky Way is brushed by early wild-geese.
At dawn tall trees still loom thick and high;
In the sunshine many distant hills awake.
one leaf having fallen south of River Huai—
I feel autumn in the waves of Donting Lake.
