In De Musica, St. Augustine continues to refine his artistic theory in the tradition of Greek thought. Musical rhythm is related to the rhythm of the universe is related to the rhythm of the body is related to the rhythm of vegetables grown ad infinitum. The passages that are of particular difficulty to modern readers are the suggestions that the artistic process is not found solely in the manipulation of the materials of the medium. The artists needs to change him or herself. “The art is an active conformation of the mind of the artist.” For St. Augustine, this means that the artist has to conform him/herself to the beautiful by moral discipline in order to create and reveal beauty. The artist has to become beautiful in order to create beauty.
