Melanchthon Circle The Melanchthon Circle was a 16th-century Lutheran intellectual network centred on the University of Wittenberg in Germany, and its leading theologian Philip Melanchthon. It was identified as significant for its interests in natural philosophy by Lynn Thorndike, in a chapter "The Circle of Melanchthon" in his multi-volume "History of Magic and Experimental Science". Among this circle were found many of the most important early proponents of the heliocentric model of Copernicus. They included Caspar Peucer who became Melanchthon's son-in-law, Erasmus Reinhold, and Georg Joachim Rheticus. Patronage came from Albert, Duke of Prussia.
Johann Arndt Johann Arndt (or Arnd; 27 December 1555 – 11 May 1621) was a German Lutheran theologian who wrote several influential books of devotional Christianity. Although reflective of the period of Lutheran Orthodoxy, he is seen as a forerunner of pietism, a movement within Lutheranism that gained strength in the late 17th century.
