Portrait of Margaretha von Mochau, wife of Gerhard von Westerburg

Bruyn utilized tempera to achieve depth and texture. The composition features a dark-robed figure set against a muted green background, with detailed rendering of the subject's clothing and accessories.

Created in 1524, the painting's provenance prior to its acquisition by the Kröller-Müller Museum is not detailed here. It represents Bruyn's established reputation as Cologne's leading portrait painter of his time.

As a Northern Renaissance work, it reflects the region's portraiture traditions. Bruyn's expertise in both portraits and altarpieces positioned him at the forefront of Cologne's artistic scene in the 16th century.

While specific influence of this portrait on later artists is not highlighted, it contributes to the broader legacy of Bartholomaeus Bruyn the Elder as a significant figure in 16th-century Northern European portraiture.
