李白传

李白字太白,兴圣皇帝九世孙。其先隋末以罪徙西域,神龙初遁还,客巴西。白之生,母梦长庚星,因以命之。十岁通诗书,既长,隐岷山。州举有道,不应。苏颋为益州长史,见白异之,曰:“是子天才英特,少益以学,可比相如。”然喜纵横术,击剑,为任侠,轻财重施。更客任城,与孔巢父、韩准、裴政、张叔明、陶沔居徂来山,日沉饮,号“竹溪六逸”。天宝初,南入会稽,与吴筠善,筠被召,故白亦至长安。往见贺知章,知章见其文,叹曰:“子,谪仙人也!”乃解金龟换酒,终日相乐。言于玄宗,召见金銮殿,论当世事,奏颂一篇。帝赐食,亲为调羹,有诏供奉翰林。白犹与徒醉于市。玄宗度曲,亟召白,令秉笔,顷之成十余章,帝颇嘉之。帝坐沉香亭子,意有所感,欲得白为乐章,召入,而白已醉,左右以水靧面以稍解,援笔成文,婉丽精切,无留思。帝爱其才,数宴见。白尝侍帝,醉,使高力士脱靴。力士素贵,耻之,摘其诗以激杨贵妃,帝欲官白,妃辄沮止。白自知不为亲近所容,益骜放不自修,与知章、李适之、汝阳王琎、崔宗之、苏晋、张旭、焦遂为“酒八仙人”。恳求还山,帝赐金放还。白浮游四方,尝乘月与崔宗之自采石至金陵,著宫锦袍坐舟中,旁若无人。

安禄山反,转侧宿松、匡庐间,永王磷辟为府僚佐。起兵,逃还彭泽;败,当诛。初,白游并州,见郭子仪,奇之。子仪尝犯法白为救免至是子仪请解官以赎有诏长流夜郎会赦还寻阳坐事下狱时宋若思将吴兵三千赴河南道寻阳释囚辟为参谋,未几辞职。

李阳冰为当涂令,白依之。代宗立,以左拾遗召,而白已卒,年六十余。
