Although the creator of the one-time altar of the Mary's Church in Selmeczbánya is still inidentified, the series is exceptionally important, for it is rare to find a composition of such quality from a concrete person in the medieval Hungarian collection.

According to the reconstruction, the altar was originally made up of eight panels, each 180x120 cm big, laid out in two vertical rows. The pictures were visible when the altar was closed, while opening the two inner wings revealed the sculptural decoration within. The representation of Christ's life on the outer side ran from the Annunciation (now lost) in the top left-hand corner to the right, continued from the bottom left-hand corner to the right with the Resurrection as the closing picture. That is the picture carrying the initials of the artist and the date (1506).

The style and solutions of the artist clearly relate him to the art of Schongauer, Dürer, and Veit Stoss, but at the same time the pictures show that he had not been ignorant of the works of Mantegna and Pollaiulo, either; on the contrary, he must have known them well.

One of the most charateristic virtues of Master M S is his mood-describing ability and marvellous colouring. The characters of the foreground dominate his pictures, the scales are not uniform, and his representation of the landscape in the background tends to describe mood and meaning, rather than the precise picture of nature, very much in the tradition of the Danube School.
