Originally quoted in Plutarch, Themistocles (18.5): (5) Of his son, who lorded it over his mother, and through her over himself, he said, jestingly, that the boy was the most powerful of all the Hellenes; for the Hellenes were commanded by the Athenians, the Athenians by himself, himself by the boy's mother, and the mother by her boy. (Bernadotte Perrin, Ed., via Perseus Project) — Original Greek: "(5) ποῦ ἂν ἦτε νῦν ὑμεῖς;’ τὸν δὲ υἱὸν ἐντρυφῶντα τῇ μητρὶ καὶ δι᾽ ἐκείνην αὐτῷ σκώπτων ἔλεγε πλεῖhttps://en.wikiquote.org/wiki/Themistocles
