It tells the story of the knight Cliges and his love for his uncle's wife, Fenice. Because of the story's de-romanticized depiction of adultery, it has been called a criticism or parody of the Tristan and Isolde romances. Cliges scholar Lucie Polak not only verifies the Tristan and Isolde reworking found in the text, but also suggests that Cliges may be modeled after Ovid's character Narcissus.

The action centers on Lancelot's rescue of the queen after she has been abducted by Meleagant, the son of Bademagu. The Abduction of Guinevere is one of the oldest motifs in Arthurian legend, appearing also in Caradoc of Llancarfan's Life of Gildas and carved on the archivolt in Modena Cathedral.

In the poem, Yvain seeks to avenge his cousin Calogrenant who had been defeated by an otherworldly knight Esclados beside a magical storm-making stone in the forest of Broceliande. Yvain defeats Esclados and falls in love with his widow Laudine.

Chretien's works include five major poems in rhyming eight-syllable couplets. Four of these are complete; Erec and Enide (c. 1170); Cliges (c. 1176), and Yvain, the Knight of the Lion and Lancelot, the Knight of the Cart, both written simultaneously between 1177 and 1181. Chretien's final romance was Perceval, the Story of the Grail, written between 1181 and 1190, but left unfinished, though some scholars have disputed this.

Erec et Enide features many of the common elements of Arthurian romance, such as Arthurian characters, the knightly quest, and women or love as a catalyst to action. While it is not the first story to use conventions of the Arthurian characters and setting, Chretien de Troyes is credited with the invention of the Arthurian romance genre by establishing expectation with his contemporary audience based on its prior knowledge of the subjects.
