《鍘美案》是一齣警世意味深厚的包公戲，內容描述宋仁宗時的狀元陳世美為迎娶公主，拋棄元配秦香蓮，並圖殺妻滅子，逼使秦香蓮至開封府擊鼓鳴冤，開封府尹包拯不畏王室強權，替秦香蓮主持公道，鍘了陳世美。這個故事凸顯了包公與強權對抗，為底層人民伸張正義的精神。然而陳世美是一個虛構的角色，在這個虛構角色的家鄉－湖北均州卻產生了與其相應的傳說，這些傳說直指陳世美其實在影射一位當地的清代進士，目的在於將他污名化，均州人民為了維護鄉譽，所以抵制《鍘美案》在當地演出。但陳世美本是虛構人物，並未指涉任何人，為何在均州形成傳說，甚至讓《鍘美案》成為均州的禁戲？大概可以歸納出三種原因，第一是包公戲導致了民間文學的衍生，第二是陳世美與地方的連結密切，第三是時間上的巧合。總而言之，這是一個戲劇演出影響民間文學，民間文學的傳播再影響戲劇演出的過程，本文將探討當中的流變與成因。
