Regum et imperatorum apophthegmata

When another man who held a seemingly impregnable rock surrendered himself together with his stronghold to Alexander, Alexander bade him to continue to rule, and gave him additional country to govern, saying that this person seems to me to show sense in trusting himself to a good man rather than to a strong place.

After the capture of the rock his friends were saying that he had surpassed Heracles in his deeds, but he remarked, No, I do not feel that my deeds, with my position as commander, are to be weighed against one word of Heracles. [*](Arrian, Anabasis, v. 26. 5, represents Alexander as boasting over the capture of the rock, which Heracles had failed to capture.)
