Psamtik III

But the story says that Psammenitus, king of Egypt, having been defeated and taken prisoner by Cambyses, king of Persia, and seeing his daughter dressed as a servant and sent to fetch water, managed to remain silent and not look at her while his friends around him were crying and lamenting.

Our historical tale could be understood the same way, or so I believe, did it not go on to say that, when Cambyses asked Psammenitus why, unfazed by the misfortune of his son and of his daughter, he could not bear to see that of his friends, he responded that he was able to express the sadness of the latter through tears but that the first two far exceeded any means of expression.
