"A snake swallowing an elephant" is how the Chinese artist Wu Guanzhong described himself. The snake was the Chinese artist in him, and the elephant was Western art. The stylistic fusion that made him one of China's leading modern artists is on view at the Asia Society Museum here in "Revolutionary Ink: The Paintings of Wu Guanzhong," which also reflects the artist's long life amid the turmoil of China's 20th century.
