Narcís Vinyoles (between 1442 and 1447 – 1517) was a Spanish poet, lawyer, and politician from Valencia. He was married to Brianda de Santángel, niece of the banker Luis de Santángel, financier of Christopher Columbus’ voyages. King Ferdinand II of Aragon (1452-1516) ennobled Vinyoles in recognition of his talents as a judge. Although a native speaker of the Catalan/Valencian dialect, Vinyoles preferred Castilian, was also fluent in Latin and the Tuscan dialect of Italian, and published works in all four language. Vinyoles co-authored works such as Obres o trobes en laors de la Verge Maria, Lo proces de les olives, and Scachs d'amor – the first document with the modern rules of chess that also uses the game as an allegory for love. The text at hand is a commentary on Psalm 51, known as the Miserere in Latin, written in prose and verse by Vinyoles and published in 1499. This incunabulum or early printed book is adorned by a lovely frontispiece consisting of a woodcut depicting King David as a late medieval knight kneeling in prayer before God in Heaven as well as decorative initials.
