The Dayton Institute of Art goes on and on. And on. In the basement, low-lit African artifacts, fragile Japanese manga and ancient Tibetan earthenware occupy endless silent rooms. The art may not feature familiar names, but it's fascinating for its age alone; some pieces date back thousands of years. On the main floor, an expansive collection of European and American art takes center stage. Regal rooms painted in deep shades of green and yellow are packed with bare-breasted women of the medieval and Renaissance periods. On the other side of the museum, paintings by Edward Hopper and Andrew Wyeth hallmark galleries devoted to contemporary art, American work after 1945 and early-20th-century modernism. Even the spaces between the galleries are beautiful. In alcoves, tall wooden doors swing out onto the Italian cloister, an open courtyard with a fountain, benches and meditative sculptures. A glass-roofed Gothic cloister is home to monthly live jazz music from March to November.
