Master of Ambrass

The Master of Ambrass was a Bohemian painter active probably in Prague at the end of the fourteenth century.

He was the creator of the Wiener Musterbuch, a set of silverpoint studies and subjects all dated to the same period, which were used as models in painters' studios.

The pictures are collected in groups of four, affixed to fourteen small framed panels.

Three independent designs also exist, depicting a philosopher and astronomer, a sibyl and John the Evangelist, and the Three Magi; these, too, were probably part of the set.

Also attributed to his hand, dubiously, is an Annunciation at the Fogg Art Museum in Cambridge, Massachusetts.
