Abstract
The aim of the paper is to offer a reconstruction of the career of Charidemos, outstanding Euboian mercenary of the fourth century B.C., who received Athenian citizenship and became an important strategos; unfortunately the main source about him is the demosthenic speech Against Aristocrates (XXIII), which gives a negative, exaggerated and probably false portrait. So in this paper other sources are highlighted in order to offer another picture of this important figure.
