It is a traditional Filipino folktale, passed down orally through generations. As such, it doesn't have a single, identifiable author.
However, several authors have adapted and retold the story in written form, such as:
* Patricio Mariano: He wrote a dramatic adaptation called "Blancaflor," which was performed in the early 20th century.
* Severino Reyes: He also wrote a stage adaptation of "Blancaflor" under the title "Prinsipe Florante at Prinsesa Laura."
* Various authors: There are many other adaptations of the story in different forms, such as children's books and educational materials.
So, while the original story has no known author, various authors have contributed to its written and performed forms.
