Under the guidance of
Monachus and the technical assistance of Van der Heyden, Frisius set up a workshop to produce globes and mathematical instruments which were praised for their quality and accuracy by contemporary astronomers such as
195:. Of particular fame were the terrestrial globe of 1536 and the celestial globe of 1537. On the first of these Frisius is described as the author with technical assistance from Van der Heyden and engraving by
