This volume is a study of Rosicrucianism in the early period of the seventeenth century with emphasis both on the local reception of the Rosicrucian pamphlets in the Baltic area and on the original group of Rosicrucian authors in Tubingen. In the first part of the book the Runic theosophy of the Swedish Rosicrucian Johannes Bureus is studied in its millenarian context, beginning with his Adulruna Rediviva of 1616. The Paracelsian prophecy of the Lion of the North is also shown to be a Rosicrucian theme. The general millenarian background to the Rosicrucian publications is then explored and implications are drawn from the Rosicrucian doctrine of the great conjunctions, from the emergence of new stars, and from their comet research.
