The Court and the Natural Sciences under Frederik II

close window

The court of King Frederik II (1534-88, reigned 1559-88) of Denmark maintained innumerable connections in all directions, both within the realm and to foreign courts. Many who cultivated interests in natural philosophy operated within patronage networks centered on the court. The court consisted of some 500 persons and was peripatetic, moving generally between castles in Jutland and Sjślland. Some natural philosophers, like the king's physician-in-ordinary, Petrus Severinus, moved with it. Others like the court astrologer, Tycho Brahe, and Viceroy Heinrich Rantzau of Schleswig-Holstein, maintained satellite quasi-courts of their own while remaining in close contact with the crown.
