[5] In 1528, German cartographer Sebastian Münster appealed to scientists across the Holy Roman Empire[6] to assist him with his description of Germany.

Gasser later took over the practice in Feldkirch, in 1538; he taught Rheticus some astrology, and helped his education, in particular by writing to the University of Wittenberg on his behalf.

[5] The second edition (1566, Basel) of De revolutionibus orbium coelestium contained the Narratio Prima with this introduction by Gasser.

[3][12] Other works include: Gasser belonged with Flacius to the humanist circle around Kaspar von Niedbruck [de], concerned with the recovery of monastic manuscripts.

Others in the group were John Bale, Conrad Gesner, Joris Cassander, Johannes Matalius Metellus, and Cornelius Wauters.
