Overbeck, Johann Friedrich (yōˈhän frēˈdrĭkh oˈvərbĕk) [key], 1789–1869, German religious painter. Expelled from the Vienna Academy because of his opposition to its classicism, he went to Rome and with Peter von Cornelius, Veit, Schadow-Godenhaus, and others, formed the group known as the Nazarenes. His first real successes were his frescoes for the Casa Bartholdy (now in Berlin) and for the Villa Massimo. Among his notable paintings are Christ's Entry into Jerusalem and Christ's Agony in the Garden. Overbeck sought to make his art serve religion. His influence was due more to the purity of his doctrine than to the power of his work, which is often lacking in pictorial appeal and in color.
