        傅岐①，字景平，仕梁。岐在禁省十余年，参与机事，亚于朱异。
        此年冬，贞阳侯萧明伐彭城，兵败，囚于魏。三年，明遣使还，述魏欲通和好，敕有司及近臣定议。左卫朱异曰：“边境且得静寇息人，于事为便。”    议者并然之。岐独曰：“魏既新得志，何事须和？必是设间，故令贞阳侯遣使，令侯景②自疑，当以贞阳侯易景，景意不安，必图祸乱。若许通好，正是堕其计中。且彭城去岁丧师，涡阳复新败退，今使就和，益示国家之弱。和不可许。”异等固执，帝遂从之。及遣使，景果有此疑，遂举兵入寇，请诛朱异。二月，侯景于阙前通表，乞割江右四州安置部下，当解围还镇。敕许之，乃于城西立盟。求遣召宣城王出送。岐固执宣城王嫡嗣之重，不宜许之。乃遣石城公大款③送之。及与景盟讫，城中文武喜跃，冀得解围。岐独言于众曰：“贼举兵为逆，岂有求和？”及景倍盟，莫不叹服。寻有诏，以岐勤劳，封南丰县侯。固辞不受。宫城失守，岐带疾出围，卒于宅。
       【注】①傅岐：南朝梁重臣傅琰的孙子。②侯景：东魏旧将，降梁，后又举兵反梁，史称“侯景之乱”。 ③大款：隆重盛大的礼节。
