German Master (16th Century) , Two Holy Martyrs: Saint Catherine of Alexandria and Saint Barbara

This fine diptych-style pair of wooden panels presents two of the most venerated virgin martyrs of the Catholic tradition, depicted as noble figures with golden halos and ornate crowns, standing against a dark green backdrop.
Saint Catherine of Alexandria (Left): Wearing a royal crown and a deep crimson mantle lined with white, she holds a large sword pointed downward and a broken spiked wheel in her left hand—her primary iconographic attribute symbolizing her miraculous survival of martyrdom by torture.
Saint Barbara (Right): Dressed in a red gown with a white cloak, she holds a golden chalice with a Host in her left hand, while her right hand rests upon a tall miniature church tower, referencing her imprisonment by her father and her association with the Holy Eucharist.
Originating from the same 16th-century German Renaissance altarpiece or predella as the panel of the four apostles and royal saints, this pair displays remarkable stylistic continuity. The delicate rendering of the facial expressions, the rich jewel-toned drapery, and the precise execution of the architectural and martyrdom attributes highlight the high technical skill of the Northern Renaissance tradition.
The reverse of the frame features historical export/collector wax stamps and annotations ("Neri di Bicci"—an older attribution attempt), underscoring the work's rich provenance and historical journey through European collections. Oil on panel , 26.5 x 9 cm each panel
