The manifestos were and are not taken literally by many but rather regarded either as hoaxes or as allegorical statements.
It is evident that the first Rosicrucian manifesto was influenced by the work of the respected hermetic philosopher Heinrich Khunrath, of Hamburg, author of the Amphitheatrum Sapientiae Aeternae (1609), who was in turn influenced by John Dee, author of the Monas Hieroglyphica (1564).
