Incendium Amoris (The Fire of Love)
Incendium Amoris
Rolle's major Latin mystical autobiography and treatise, written before 1343, describes his own experience of three supernatural gifts — calor (a physical warmth in the chest), dulcor (ineffable sweetness), and canor (heavenly music heard by the soul) — and explains the four purgative stages toward union with God. It survives in 44 Latin manuscripts plus one contemporary Middle English translation, and Margery Kempe had a priest read it aloud to her alongside other devotional works. While Rolle addressed his vernacular works specifically to noble and gentlewoman patrons, the Incendium circulated widely in clerical and monastic libraries attached to noble households; its extraordinary manuscript survival — across 44 Latin copies and a Middle English version — marks it as the most internationally circulated product of 14th-century English mysticism, reaching Carthusian houses on the Continent as well as English court circles.
