Adapt a myth into script form, using dialogue and stage directions to convey what narration originally handled.
Turning a myth into a script means translating one kind of storytelling into another. Narration can simply tell you a character is furious or that years pass in a sentence; a script has to SHOW everything through dialogue characters actually say and stage directions describing what an audience would see. Nothing a narrator quietly explained can survive the adaptation unless it becomes visible or audible on a stage.
The Greek myth of Persephone and Demeter explains why the seasons change. Hades, god of the underworld, takes Persephone to be his queen. Her mother, Demeter, goddess of the harvest, grieves so deeply that she neglects the earth, and every crop begins to fail. Zeus brokers a deal: Persephone will spend part of each year with her mother and part in the underworld. Whenever she returns to Demeter, the earth blooms again -- spring and summer. Whenever she returns to the underworld, Demeter's grief returns with her, and the earth turns cold -- fall and winter.
Mastery looks like: They can convert a narrated passage from a myth into dialogue and stage directions that convey the same information visibly and audibly.
Common stumbles: Writing dialogue that simply restates the narration word for word, rather than translating feelings and time passing into something an audience could actually see or hear.
