OIL PAINTING: Rue Halevy, Seen from the Sixth Floor, 1878
A contemporary of Degas, Monet, and Renoir, Gustave Caillebotte was an engineer by profession. A highly intellectual artist, Caillebotte based his most famous painting on mathematical perspectives, but his precision of composition never overwhelms the spontaneity of the moment captured -''Rue Halevy, Seen from the Sixth Floor''.
