For his materials, he must draw continually, as I have said, upon his unfailing memory of ancient story; and memory must be backed by taste and judgement. He must know the history of the world, from the time when it first emerged from Chaos down to the days of Egyptian Cleopatra. These limitations we will concede to the pantomime's wide field of knowledge; but within them he must be familiar with every detail:--the mutilation of Uranus, the origin of Aphrodite, the battle of Titans, the birth of Zeus, Rhea's deception, her substitution of a stone for her child, the binding of Cronus, the partition of the world between the three brothers. Again, the revolt of the Giants, Prometheus's theft of fire, his creation of mankind, and the punishment that followed; the might of Eros and of Anteros, the wanderings of the island Delos, the travail of Leto, the Python's destruction, the evil design of Tityus, the flight of eagles, whereby the earth's centre was discovered. He must know of Deucalion, in whose days the whole world suffered shipwreck, of that single chest wherein were preserved the remnants of the human race, of the new generation born of stones; of the rending of Iacchus, the guile of Hera, the fiery death of Semele, the double birth of Dionysus; of Athene and Hephaestus and Erichthonius, of the strife for the possession of Athens, of Halirrhothius and that first trial on the Areopagus, and all the legendary lore of Attica. Above all, the wanderings of Demeter, the finding of Persephone, the hospitality of Celeus; Triptolemus's plough, Icarius's vineyard, and the sad end of Erigone; the tale of Boreas and Orithyia, of Theseus, and of Aegeus; of Medea in Greece, and of her flight thereafter into Persia, and of Erechtheus's daughters and Pandion's, and all that they did and suffered in Thrace. Acamas, and Phyllis, and that first rape of Helen, and the expedition of Castor and Pollux against Athens, and the fate of Hippolytus, and the return of the Heraclids,--all these may fairly be included in the Athenian mythology, from the vast bulk of which I select only these few examples. 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.
