With her arrival in Moldavia, Maria underscored the relative impact of Byzantine politics and culture at Stephen's court. She also accepted Byzantine communion with the Catholics, acting as an agent of Catholic influence before returning to Eastern Orthodoxy. Stephen likely married her for political reasons, hoping to conquer the principality, though he lost interest in her when that proved impossible. According to conflicting readings, the Prince either divorced her to marry the Wallachian Maria Voichița (who in any case became her successor), or she lived estranged from Stephen without a formal separation. Her portrait is mysteriously absent from a miniature of the Humor Monastery "Gospel", possibly removed by her husband.
