For a time he taught at Vienna; in his old age, 1545–49, he lived in the house of Wolfgang Salm, Bishop of Passau. His portrait by Wolf Huber (c. 1485–1553), executed about 1540, when he was about seventy years old, is in the Kunsthistorisches Museum, Vienna.
His main geographical treatise, ''Schondia'', was published under the title ''Quae intus continentur Syria, Palestina, Arabia, Aegyptus, Schondia, Holmiae...'' at Strasbourg in 1532. He was also a publisher of maps where he influenced Gerardus Mercator, who mentioned Ziegler's maps contained numerous inconsistencies and errors.
The Swedish historian Johannes Messenius claimed that Ziegler served as a professor of mathematics at Uppsala University in 1540. However, this assertion has later been challenged by subsequent scholars, including Johannes Schefferus and Johann Georg Schelhorn. Provided by Wikipedia
