Passage 2.20.4
τὸ δὲ μνῆμα τὸ πλησίον Χορείας μαινάδος ὀνομάζουσι, Διονύσῳ λέγοντες καὶ ἄλλας γυναῖκας καὶ ταύτην ἐς Ἄργος συστρατεύσασθαι, Περσέα δέ, ὡς ἐκράτει τῆς μάχης, φονεῦσαι τῶν γυναικῶν τὰς πολλάς· τὰς μὲν οὖν λοιπὰς θάπτουσιν ἐν κοινῷ, ταύτῃ δὲ---ἀξιώματι γὰρ δὴ προεῖχεν---ἰδίᾳ τὸ μνῆμα ἐποίησαν.
The nearby tomb they call that of Choreia, a maenad. They say she and other women marched together with Dionysus against Argos, and that Perseus, having prevailed in battle, slew most of the women. The rest were buried together in a common grave, but this woman—since indeed she surpassed the others in dignity—they honored with a separate tomb.
