S.'s prints, described above, he copied prints by the Housebook Master, including some now otherwise lost, Martin Schongauer, and many other German engravers.His famous and very fine late series on the "Life of the Virgin" appears to have been based on drawings by Hans Holbein the Elder or his workshop, and he may have entered into a regular commercial relationship with Holbein.However, some 20% or more of his prints, around 150, seem to be original compositions.
