Stefan Lochner was a German painter working in the late International Gothic period. His paintings combine that era's tendency toward long flowing lines and brilliant colours with the realism, virtuoso surface textures and innovative iconography of the early Northern Renaissance. Based in Cologne, a commercial and artistic hub of northern Europe, Lochner was one of the most important German painters before Albrecht Dürer. Extant works include single-panel oil paintings, devotional polyptychs and illuminated manuscripts, which often feature fanciful and blue-winged angels. Today some thirty-seven individual panels are attributed to him with confidence.
