《后汉书·列传·独行列传》
因为它的名称体例虽然不同，而操守行事都很出色，所以总归入《独行篇》，庶几可以作为史的缺文，记述脱漏而已。
以其名体虽殊，而操行俱绝，故总为《独行篇》焉。庶备诸阙文，纪志漏脱云尔。
Because although their names and forms may differ, their conduct and actions are all outstanding, so they are all included in the "Solitary Chapter", so that it may serve as a supplement to the history, and record that which was omitted.
