Who wrote the story echo and narcissus?

The story of Echo and Narcissus is a Greek myth, so there is no single author. It was passed down through oral tradition for centuries before being written down by various authors.

Here are some of the most notable sources:

* Ovid: His version in the *Metamorphoses* is one of the most famous and influential.

* Pausanias: The Greek geographer wrote about the myth in his *Description of Greece*.

* Hyginus: He included the story in his *Fabulae*, a collection of myths.

So, while no single person can be credited as the author, these writers and others contributed to the story's evolution and transmission over time.
