As the other answer said, the Orpheus and Eurydice myth has no first author. Nevertheless, a modern writer, Hugh Lupton, retold the story in a book for middle schoolers published in 2013. His book is called Orpheus and Eurydice.
In it, he retells the classic story. While details and versions of the story change from author to author, Lupton tells the following version:
Orpheus is an extraordinary musician. His music enchants the world. He falls in love with and marries Eurydice. Sadly, however, she is bitten by a poisonous snake and dies soon after the wedding. Orpheus is so grief stricken that he goes down to the underworld to retrieve his bride. He plays his music so beautifully that the ruling god and goddess of the underworld, Hades and Persephone, allow Orpheus to leave with Eurydice. They establish one rule, however: he must not look at her until they are back on earth. Naturally, Orpheus looks at his wife. More happens, but I will leave you to read the story.
