Dominic of Prussia was a 15th-century Carthusian monk and theologian born in Gdańsk. After a period of wandering following his studies at the University of Krakow, he joined the Carthusian Order in 1409 under the guidance of Adolf of Essen. He lived a life of intense religious devotion and penance, eventually serving as a master of novices and a vicar. He is widely recognized for his contributions to contemplative prayer and for authoring seventeen religious treatises during his lifetime.
