The original Rosicrucians may never have existed, except as a literary device. The hidden fraternity has been revived time and again since its first appearance in the early 16th century, and esoteric Freemasonry and most Western occult movements have some relationship to the Rosy Cross. Modern movements calling themselves Rosicrucian may have only a tenuous link to the original. The original Rosicrucian documents were the Fama fraternitatis, circa 1611, and the Confessio fraternitatis, circa 1615. Later in the century, The Chymical Wedding of Christian Rosenkreutz was published.
