to an invisible place, to Hades Ph. 80d. Cp. “Old Gaunt indeed, and gaunt in being old”: Shakespeare. Sometimes this figure deals with the same word taken in different senses (homonyms): ἅμα γὰρ ἡμεῖς τε τῆς ἀρχῆς ἀπεστερούμεθα καὶ τοῖς Ἕλλησιν ἀρχὴ τῶν κακῶν ἐγίγνετο ‘no sooner were we deprived of the first place than the first disaster came upon the Greeks’ 4.119.
