I guess if you’re going to use gold and silver to paint with, you make sure it’s right.
Hoefnagel (who as far as I can tell was just Flemish, not Hungarian) is also known as a maker of marginalia and miniatures. Precision counts there, too. He helped create “still life” as a genre.
Bocskay (who was Croatian) was the court calligrapher for Emperor Maximilian II.
