Henning Arnisaeus

[3] After travels in England and France, he became court physician to Christian IV of Denmark.

[1] At Helmstedt, Arnisaeus became a pupil of Cornelius Martini, a Lutheran metaphysician who also influenced Hermann Conring.

[4][5] He used an Aristotelian analysis to distinguish in political thought between the civitas and the res publica, in a critique of Jean Bodin, Johannes Althusius, Busius (Paulus Buis or Buys, died 1617), and Bartholomäus Keckermann.

[7] That work also incorporated Tacitean ideas, under the influence of Arnold Clapmar, within the Aristotelian and humanist framework he proposed, attacking the Ramist critics of Aristotle.

In 1610 in De jure majestatis he took Bodin's part against the mixed state; even so, in relation to Holy Roman Empire and its institutions he admitted that sovereignty could in practical terms be distributed among several authorities.
