 In the spring of 1572, Lipsius moved to Vienna where he was introduced to the humanist circle at Maximilian’s court, which included Ogerius Busbequius, Joannes Sambucus and Stephanus Pighius. In October Lipsius obtained the chair of history at the Lutheran University of Jena. He also completed his edition of Tacitus, which he dedicated to Emperor Maximilian II and in which the Annals were distinguished from the Histories for the first time. He left Jena briefly in 1573 to marry Anna van den Calstere in Cologne and then for good in 1574, when he returned to the Low Countries.
