Nicolás Factor was a 16th-century Spanish Franciscan priest, painter, and itinerant preacher born in Valencia. Despite his desire to serve in foreign missions, he spent his life preaching throughout his home region. He was recognized for his intense devotion, which included performing acts of self-mortification prior to delivering sermons. Throughout his career, he also served as a spiritual director for religious houses in Madrid and moved between various convents before his death in Valencia.
