Crows and Cryptomeria, late 16th century, Unknown Japanese, 64 1/2 x 136in. (163.8 x 345.4cm), Six-panel folding screen; ink on paper, Japan, 16th century, A crow's cry is considered an ill omen in China and Japan, yet crows became a standard theme among Japanese artists from the 1500s onward. They may have been inspired by imported Chinese paintings of myna birds, which are not native to Japan, substituting the native species of crow instead. Painters of folding screens (which usually come in pairs) often paired a scene of raucous black crows with a quiet image of white egretsthe contrast heightened by the birds' coloration. Artists of the Hasegawa school, which originated with the celebrated painter Hasegawa Tōhaku (1539-1610), specialized in the impressionistic handling of ink brushwork seen here in the sketchily rendered branches.
