Editing Gerardus Mercator (section)

===University of Leuven, 1530–1532===
From a famous school, Mercator moved to the famous [[Old University of Leuven|University of Leuven]], where his full Latin name appears in the matriculation records for 1530.{{sfn|Crane|2003|loc=Chapter 4}} He lived in one of the teaching colleges, the Castle College, and, although he was classified as a pauper, he rubbed shoulders with richer students, amongst whom were the anatomist [[Andreas Vesalius]], the statesman [[Antoine Perrenot de Granvelle|Antoine Perrenot]], and the theologian [[George Cassander]], all destined to fame and all lifelong friends of Mercator.

The general first degree (for [[Magister degree|Magister]]) centred on the teaching of philosophy, theology and Greek under the conservative [[Scholasticism]] which gave prime place to the authority of [[Aristotle]].{{efn| name=UniStat}} Although the trivium was now augmented by the [[quadrivium]]{{efn|The trivium and the quadrivium together constitute the [[seven liberal arts]]}} (arithmetic, geometry, astronomy, music), their coverage was neglected in comparison with theology and philosophy and consequently Mercator would have to resort to further study of the first three subjects in years to come. Mercator graduated as Magister in 1532.{{efn| name=MathGenealogy}}
