The Collectio Camerariana collection of letters (now held in the Staatsbibliothek München) includes his correspondence from 1621 as well as several letters from Philipp Melanchthon, Martin Luther, Ulrich Zwingli, Jakob Micyllus, Desiderius Erasmus and the poet Georg Fabricius, mostly written to his grandfather Joachim—these form an important source for the Protestant Reformation and the Counter-Reformation.
