ALPHA OMEGA ARTS
"Pietà" (1476) by Carlo Crivelli at The Metropolitan Museum of Art, NYC
This emotionally charged image of the Pietà comes from the uppermost tier of an altarpiece Carlo Crivelli painted for the church of San Domenico at Ascoli Piceno in the Marches. Known as the Demidoff altarpiece (below), it is widely considered Crivelli's masterpiece; the principal panels are in the National Gallery, London. Crivelli's art contrasts ornamental effects with details of extreme realism—such as the wounded hand hanging over the tomb’s edge. The fine seventeenth-century frame was made for it by the Barberini family in Rome whose emblem—the bee—adorns each corner. On view at The Met Fifth Avenue in Gallery 627 [More]
The Demidoff Altarpiece by Carlo Crivelli, National Gallery, London
This many-panelled altarpiece, or polyptych, was painted by Crivelli in 1476 to sit on the high altar of the church of San Domenico in Ascoli Piceno, east central Italy. The polyptych was composed of the central panel and eight smaller panels with saints, also in the Gallery. Originally there was a predella (a lower section of the altarpiece), now lost, and a lunette-shaped Lamentation above (now in New York, Metropolitan Museum of Art).
