 According to Nancelius, Ramus used to gather around him in his own house a number of proficient mathematicians, so that they could help him to understand what he would later teach his students. Yet, from the very beginning, he was convinced of the importance of mathematics. Nancelius thinks his master’s keen interest in mathematics was a consequence of his banishment for some time from teaching philosophy (Ramus, Collectaneae praefationes, epistolae, orationes, p. 409; Nancelius Petri Rami Vita: 197–201; Goulding 2006: 74, 2010: 20). In any case, he improved his abilities in both Greek and mathematics, and in his will he stipulated that the holder of the chair he wanted to endow should be an expert in both. Ong’s negative judgment of Ramus’ mathematical abilities may be correct (Ong 1958: 27); nevertheless, his enthusiasm for this field was crucial to the future history of Ramism.
