Lucian De saltatione 41

[41] And next comes Megara, with Nisus and Scylia, the purple lock, the expedient of Minos, and his ingratitude towards his benefactress. ¹ To these succeed Cithaeron, with all that befell the Thebans and the house of Labdacus; the advent of Cadmus, the heifer’s taking ground, the serpent’s teeth, and the emergence of the Sown Men; further, the transformation of Cadmus into a serpent, the rising of the walls to the music of the lyre, the madness of the wall-builder, ² the boastfulness of his wife Niobe, and her grief-stricken silence, the story of Pentheus and of Actaeon, the story of Oedipus, Heracles with all his labours, and the murder of his children.

[41] Then in Megara we have Nisus, his daughter Scylla, and his purple lock; the invasion of Minos, and his ingratitude towards his benefactress. Then we come to Cithaeron, and the story of the Thebans, and of the race of Labdacus; the settlement of Cadmus on the spot where the cow rested, the dragon’s teeth from which the Thebans sprang up, the transformation of Cadmus into a serpent, the building of the walls of Thebes to the sound of Amphion’s lyre, the subsequent madness of the builder, the boast of Niobe his wife, her silent grief; Pentheus, Actaeon, Oedipus, Heracles; his labours and slaughter of his children.
