Calprenède was known along with d'Urfé and Scudéry for promoting literary and cultural aesthetics of delicate refinement exalting chivalric virtues partly through long works of romance fiction that constitute the most significant examples of the Roman de longue haleine, literally the "long-winded novel." His most popular works in that genre include Cassandre (1642-45), which stretched to ten volumes and was translated into English as Cassandra, the Fam'd Romance (1652), and Cléopâtre (1646-57), a twelve volume work, translated as Hymen's Praeludia, or Love's Masterpiece (1665).
