"Le Poème du Rhône, en XII chants. Texte Provençal et Traduction Française" by Frédéric Mistral is a collection of poetry published in 1897. This twelve-canto epic follows boatmen journeying down the Rhône River from Lyon to the Beaucaire fair, capturing ancient river traditions that blend Christianity with pagan beliefs. A passionate love develops between Prince Guilhem d'Orange and Anglore, a young gold-seeker. The poem weaves together Provence's history with the humble lives and romances of its common people.
