court painter in Gottorf; in 1655 he lives in Flenborg again (ThB)

The ‘Contrefacteur Broderus Mathisen’ from Husum was appointed on 10 November 1659 as a court painter to the Elector with a salary of 200 Thaler and free board and lodging for himself and a young pupil or otherwise a cash sum. These provisions were renewed on 6 October 1665 with the same conditions, except that he would now receive 20 Thaler rent money instead of free board and 3 Thaler per week cost money for a boy. For this Mathisen had to make all works for the Elector for a small price or even for half the cost, to wit: ‘1) a Portrait life-size, most diligently painted for 20 Thaler; 2) a half portrait to the knee for 10 Thaler; 3) a breast piece or even smaller for only 5 Thaler, and furthermore to paint all else, that His Highness wished for, also for half the price. Furthermore, he had to buy all the pigments he needed for these paintings himself and he had to keep an eye on all the already existing paintings, most diligently, and to repair the same, just as His Highness wishes, and lastly to teach everybody, whomsoever expressed a wish to draw, on His Highness’s most gracious, in a most honorable and diligent way’ (translated from Seidel 1890); in this period there still are contacts with the court in Gottord (Heiberg 1994)
