Marburg is best known as the site of a failed rapprochement between Luther and Zwingli. It would be wrong, however, to only think of the city as a place of defeat.  To the contrary, supported by Philip the Magnanimous, it became the seat of what is now the oldest Protestant university in the world.  Situated as it was between the Lutherans and Reformed, its faculty represented a catholic and irenic Evangelical expression most famous for their emphasis in the humanities and natural philosophy.
