Savery, who was working for Emperor Rudolph II in Prague at that time. In Prague he gave up painting and concentrated entirely on engraving, an art in which the famous Sadeler, who was also very busy at Emperor Rudolph II's court at the time, was involved. became his master. M. seems to have worked in Sadeler's house for a long time and several of his sheets are said to be labeled with Sadeler's name.
