The Raven is an Italian literary fairy tale written by Giambattista Basile in his 1634 work, the Pentamerone.
[1] The story is a man winning a bride for his brother the king, and then having to protect the couple from perils that he can not tell anyone about, without being turned to stone.
[2] It is an unusual variant, in that most tales feature the main character as a servant rather than a brother.
It affected his health until his brother Jennariello asked what was wrong with him and finally learned the story.
Jennariello dressed as a peddler and showed Liviella hoods, handkerchiefs, and other goods, and persuaded her to come to the ship to see his better wares.
