A summary of the Quadripartitum found in Nicolaus Gugler’s personal notebook dated 1536-1537, when he was a student in astronomy at the University of Wittenberg under Joachim Rheticus and Erasmus Reinhold. This summary may derive from, or be somehow related to, the teaching of Philipp Melanchthon, who read the Tetrabiblos at Wittenberg from 1535 to 1537 (S. Kusukawa, The Transformation of Natural Philosophy. The Case of Philip Melanchthon, Cambridge, 1995, 135 n. 69). See also C.2.22.
