小孤山新修一柱峰亭记

[元] 虞集

  延祐五年,某以圣天子之命,召吴幼清先生于临川。七月二十八日,舟次彭泽,明日,登小孤山,观其雄特险壮,浩然兴怀,想夫豪杰旷逸名胜之士,与凡积幽愤而怀感慨者之登兹山也,未有不廓然乐其高明远大,而无所留滞者矣。

  旧有亭在山半,足以纳百川于足下,览万里于一瞬,泰然安坐,而受之可以终日。石级盘旋以上,甃结坚缜,阑护完固,登者忘其险焉。盖故宋江州守臣厉文翁之所筑也,距今六十二年。而守者弗虔,日就圮毁,聚足以涉,颠覆是惧。

  至牧羊亭上,芜秽充斥,曾不可少徙倚焉。是时,彭泽邑令咸在,亦为赧然愧,赩然怒,奋然将除而治之。问守者,则曰:“非彭泽所治境也。”乃相与怃然而去。 明日,过安庆,府判李侯维肃,某故人也,因以告之。曰:“此吾土也,吾为子新其亭,而更题曰‘一柱’,可乎?夫所谓‘一柱’者,将以卓然独立,无所偏倚,而震凌冲漱,八面交至,终不为之动摇;使排天沃日之势,虽极天下之骄悍,皆将靡然委顺,听令其下而去。非兹峰其孰足以当之也耶!新亭峥嵘在吾目中矣,子当为我记之。”

  李候真定人,仕朝廷数十年,历为郎官,谓之旧人,文雅有高材,以直道刚气自持,颇为时辈所忌。久之,起佐郡,人或愤其不足,候不屑也。观其命亭之意,亦足以少见其为人矣。且一亭之微,于郡政非有大损益也,到郡末旬日,一知其当为,即以为己任,推而知其当为之大于此者,必能有为无疑矣。 (选自《道园学古录》卷七,有删节)

  【注】①某:我。 ②甃结:砖块建筑。 ③聚足:登台阶一步一停。 ④徒倚:来回走动。⑤震凌冲激:指江水侵凌撞击。⑥旧人:有资历的老臣。
