Abstract
This article does not attempt, except in a general way, to indicate Plutarch's sources for this Life, since any such attempt, in the absence of much of the relevant literature, is foredoomed to failure. It aims rather at showing the different types of biographical literature which grew up around this figure and which form the basis of Plutarch's Life, and to show what seems the most probable relationship of this Life to the biography of Nepos and to Cicero's Cato, both of which works have, in the present writer's opinion, been too readily assumed by some critics as Plutarch's sources. We may most conveniently deal with Plutarch's Life first, and then pass on to Cicero's and Nepos' presentations
