Pope Gregory I (540 - March 12, 604) commonly known as Saint Gregory the Great, was Pope from September 3, 590 to his death in 604. Gregory is well known for his writings, which were more prolific than those of any of his predecessors as pope. He is also known as St. Gregory the Dialogist in Eastern Christianity because of his Dialogues. He is the patron saint of musicians, singers, students, and teachers. The mainstream form of Western plainchant, standardized in the late 9th century, was attributed to Pope Gregory I and so took the name of Gregorian chant.
