In his autobiography, Johann Valentin Andreae (1586–1654) claimed that the anonymously published Chymical Wedding of Christian Rosenkreutz was one of his works, and he subsequently described it as a ludibrium. In his later works, he makes alchemy an object of ridicule and places it along with music, art, theater, and astrology in the category of less serious sciences. According to some sources, his role in the origin of the Rosicrucian legend is controversial.[12] But according to others, it was generally accepted.[13]
