What is the significance of the Arundel Manuscripts in Freemasonry?

The Arundel Manuscript (Ar. MSS. 91, f. 218b), a twelfth-century Latin text held in the British Museum, serves as an important early link between medieval operative traditions and modern Freemasonry 1. It contains a detailed version of the legend of the Quatuor Coronati, or Four Crowned Martyrs, who were traditionally revered as patron saints of medieval stonemasons 1, as quatuorcoronati.com records.

The manuscript helps clarify historical variations in the legend, particularly why five individuals are frequently named in prayers while four appear in Masonic symbolism 1. According to the Arundel text, Simplicius was a fellow stonecutter who converted to Christianity under the influence of the original four artisans—Claudius, Castorius, Symphorian, and Nicostratus—and suffered martyrdom alongside them 1. The narrative describes these craftsmen as skilled sculptors working in Pannonia under Emperor Diocletian, secretly practicing Christianity and executing their stonework in the name of Christ 1.

Although Italian in origin, the legend recorded in the manuscript migrated across Europe alongside building guilds and Craft lodges 1. Scholars consider the Arundel text significant because it preserves the early Christian hagiology that shaped the traditional history and symbolism of the operative craft prior to its development into speculative Freemasonry 1.
