"Johannes Hoornbeek (4 November 1617, Haarlem – 23 August 1666, Leiden), was a Dutch Reformed theologian. He was a student and a follower of Gisbertus Voetius, writing with him on spiritual desertion. Like his teacher Voetieus, he was also later a professor of theology at the University of Leiden and University of Utrecht. The two universities were closely related in the 17th century, and both the teacher and his students participated in the intellectual "Utrech Circle." Another member of the circle was Hornbeek's student colleague Andreas Essenius. The circle was also known as De Voetiaanse Kring (The Voetian Circle), and it was one of the most influential intellectual circles of the Dutch second Reformation." - (en.wikipedia.org 23.05.2021)
