Starting from Italy the intellectual-cultural movement of the Renaissance-Humanism spread all over Europe from the middle of the 14th until the end of the 16th century. At the turn to the modern period the movement covered also the universities of the Holy-Roman-Empire and shaped science, teachings and everyday life for a long time. In addition to the common linguisticality (latin) it boosted communicative-integral elements, which became visible in the humanist’s natural-scientific comprehension. It left lasting marks in institutions of science, while communicating its spectrum of topics, its operating principles and its secular lifestyle. The humanist stood in the center of scholarly high regard. The present volume includes conbtributions on the establishment of the „Sciencia mathematica“, of astronomy, geography, musical education, scientific book production, on outstanding humanists such as Bernhard Perger, Johannes Schöner, Konrad Celtis as well as on the every day life of the masters and students at the university.
