You could start with the Myth Map to find stories that come from certain areas.
Find a story and you’ll be able to listen and read along. Click on the auto on/off to make the story continue automatically or stop after each page.
For each story, you also can read the text-only version, see a gallery of images connected to the story, related research work from students (“Your Work”), information about the origin of the stories, and a glossary of relevant words.
Creating your own requires signing up through a teacher, and it’s not free. But you can always create your own using different tools and posting the stories in your portfolios.
