The justly famous "Wave" belongs to this series. Here for the first time in our survey of the prints do we find elemental fury depicted with grandiose eloquence. In the majestic composition of the "Great Tree" (Plate 50) the calm sublimity of nature and the infinitely minute, vermin-like aspect of man is superbly expressed. In the "Tama River" (Plate 49) Hokusai gives us a sweep of wave and shore, mist and mountain, that his great predecessors, the landscape-painters of Sung days in China, might have envied. In all these prints he relates man and nature to each other with a vividness and dramatic power foreign to his great rival Hiroshige. The world which Hokusai pictures in this series is not the real world, but Hokusai's highly personal translation of it into terms of superb imagination. A thousand memory-stored impressions combine to make the sharp composite of each design; and it is to use the term in its technical Platonic sense, the Idea of the scene that he flashes before us. Herein lies the abnormal vitality that emanates from these pictures. "We feel," says Mr. Binyon, "that the world holds more wonders than we dreamed of, sources of power and exhilaration which Hokusai has revealed, and which we may go and discover for ourselves." Hokusai's other great work was a series of ten upright prints of very large size, "The Imagery of the Poets." It returns in feeling, though not in technique, to the style of the classic masters; and remains, because of its high seriousness of mood and its sweeping magnificence of composition, at the very top of all Hokusai's work. Of all his thousands of designs, the one that is supreme is probably the print of this set which depicts the famous Chinese poet Li Peh beside the chasm and cascade of Luh. Even his latest years were crowded with continued efforts. In 1849, at the age of eighty-nine years, he died. Fine and well-preserved Hokusai prints are not common. His "Poets" and really brilliant impressions of his "Thirty-six Fuji" are very rare, particularly the former. Poor impressions of the latter are numerous. Practically all of Hokusai's most famous prints have been reproduced, and the collector must be on his guard against these worthless sheets. One of the best-known judges in Europe was recently deceived by a fraudulent set of the "Poets." Hokusai's fine bird-and-flower designs and his large early surimono are rare; as also are good copies of his famous books, the "Mangwa" and the "One Hundred Views of Fuji." Numerous late blurred impressions of these are extant, and should be avoided. His other books are not uncommon. [Illustration: HOKUSAI: THE MONKEY BRIDGE--TWILIGHT AND RISING MOON. Size 14½ × 6½.
