Drebbel was an engraver by profession when living in Holland at Haarlem and Alkmaar as a pupil of his brother-in-law, Hendrick Goltzius.
In the right hand lower corner of Music and Astronomy we see clearly Drebbel’s monograms,
probably the same kind of monograms with which he later hall-marked his instruments.
