Koriusai's variations on the limited themes whose treatment is possible in this narrow space display daring, originality, and power of concentrated selection. He is the supreme master of the pillar-print; no one else has produced so many fine ones, and practically all his finest work is in this form. The infinite variety of his designs and the fertility of his invention make a series of his pillar-prints one of the most absorbing features of a fine collection. In one print (Plate 17), he dashes the intense black line of a screen down through the middle of his picture and sets the delicate eddies of a child's and a young girl's garments playing around its base. In a second (Plate 18), a girl in robes of gorgeous colour stands like a calm peacock, with glowing orange combs alight in her hair; while in a third (Plate 16), the whole space waves and sings with the forms of grasses, a flying cuckoo, and a maiden carried in the arms of her lover through fields of spring. And in a fourth (Plate 17), he draws the figures of two women, one behind and a little above the other, the one in the background luminous with soft neutral tints, the one in the foreground robed in a black whose intensity cuts sharply through the otherwise monotonous sweetness of the picture. To the grace of Harunobu, Koriusai has here added a vigour all his own, and a richness surpassing that of his teacher. To-day Koriusai's small prints are rather rare, as are also the birds and the large-size sheets. His pillar-prints, which are his greatest works, were produced in such numbers that, contrary to the rule that applies to the pillar-prints of all other designers, a good many of them have survived. It is still possible to secure examples that are among the foremost of all print treasures. [Illustration: SHIGEMASA: TWO LADIES. Size 28½ × 5. Unsigned. KORIUSAI: A COURTESAN. Size 27 × 4½.

The few prints of his that are known have a grace of line that might well be a son's heritage, if such things were inheritable. The unholy rascal Shiba Kokan alleges that this name was one which he himself used, as well as Harunobu's; it is reported, on the other hand, that it is merely Koriusai's early name. It is probable that Kokan's statement must be believed. [Illustration: HARUSHIGE.]
