Master M. S. (Hungarian: M. S. Mester, German: Meister M. S., Slovak: Majster M. S.) was a 16th-century painter in Central Europe in late Gothic and early Renaissance art.
He was active in Banskรก ล tiavnica (to 1918 Selmecbรกnya in the Kingdom of Hungary, since 1993 in Slovakia) and probably led a workshop there. Since his true name is unknown, he is sometimes identified with various other Gothic "masters". German art historians generally identify him with J. Brieu, a painter from Augsburg. Also some art historians identify him with the engraver Master MZ, often identified as Matthรคus Zaisinger (1498โ1555), a German goldsmith from Munich. According to other research the master could have been a Hungarian painter called Sebestyรฉn, whose name is mentioned in the charter of Banskรก ล tiavnica in 1507. The art historian Miklรณs Mojzer noted the similarities between this work and that of the painter who accompanied Veit Stoss and made the passion paintings in an altar now in the Esztergom Christian Museum and he called him Marten Swarcz. His art combining dramatic depth and colourful decorative formation is akin to that of the German painters Martin Schongauer, Albrecht Dรผrer, J. Brieu and mainly Mathias Grรผnewald.
Only seven of his panel paintings are known out of eight which used to decorate the high altar of a church in Banskรก ล tiavnica. It was believed that the altar was in the Saint Catherine Church, but according to the new research the pictures were part of the altar in the Virgin Mary Church, later rebuilt into the fortress called the Old Castle. Now there are four Passion paintings in Esztergom,Hungary, in the Christian Museum; the painting "The Birth of Christ" is held in Svรคtรฝ Anton (formerly known also as Hontszentantal) near Banskรก ล tiavnica, and The Adoration of the Magi is in the Museum of Lille in France. His painting entitled "The Visitation" depicts the meeting of the two saints, the Virgin Mary and St. Elizabeth, is in Budapest, in the Hungarian National Gallery.
There are also three more-than-life-size wood-carved polychromed sculptures preserved which originally belong to the same altar. The statue of Madonna is in the Saint Catherine Church of Banskรก ล tiavnica, the statues of Saint Catherine and Saint Barbara are in the art gallery of the Slovak Mining Museum in Banskรก ล tiavnica.
At the Old Castle in Banskรก ล tiavnica, a half-sized maquette of the altar is exhibited, featuring full-coloured photocopies of all the known panel paintings by Master MS, as well as fragments of decorative wood carvings which presumably were parts of the altar.
