Returning to Utrecht in about 1590 (by 1592 at the latest),[REF] Wtewael established a workshop and joined the saddlemakers' guild (which in Utrecht then covered painters as well) as a painter and began producing paintings, drawings, engravings, and stained glass [REF].
He married Christina Wtewael van Halen (1568-1629), whose portrait of 1601 makes a pair with the self-portrait illustrated.
