Maro Dafnikis was an author, although she was primarily known for being very tall.
Historical breadcrumbs lead to several vague statements in the literature, crediting her for writing a fable called Two Dogs and a Stone. The fable is claimed to have had a wide influence on the ancient world, although it's not specified in what way.
She is also credited for founding an organization called “Composers of the Ancient Scrolls”, but this claim is even more dubious.
