Madonna and Child with Saints Nicholas and Catherine and a Donor by Gentile da Fabriano was painted around 1400 using tempera, oil, and gold on a poplar panel. The work shows the Virgin Mary enthroned with the Christ Child, flanked by Saint Nicholas of Bari and Saint Catherine of Alexandria, with a kneeling donor at the lower left. The composition is set against a gold ground, typical of late medieval Italian panel painting, and features two fruit-bearing trees with small angels or putti among the branches. The central figures are depicted with delicate modeling and fine detail, especially in the rendering of textiles and the gold embroidery on Mary's mantle.

Saint Nicholas is identified by his bishop's mitre and crozier, while Saint Catherine holds a martyr’s palm and the wheel, her traditional attribute, is visible near her feet. The donor, dressed in black, kneels in prayer at the feet of the Virgin, signifying his piety and patronage. The background is richly gilded, and the figures are set on a carpet of flowers, adding to the sense of sanctity and preciousness. Panel paintings of the Madonna and Child with saints were common in Italy around 1400, serving both as altarpieces and objects of private devotion.

Gentile da Fabriano was active in the late 14th and early 15th centuries and is known for his refined International Gothic style, characterized by elegant figures and lavish use of gold. The panel is in the Gemäldegalerie in Berlin.
