Arugori; Koronbusu no tamago (Allegory: Columbus's Egg) / Ichimoku-shu (First Thursday Collection, Vol 4)

Arugori; Koronbusu no tamago (Allegory: Columbus's Egg), from Ichimoku-shu (First Thursday Collection, Vol. 4), is a print by Onchi Koshiro, the sosaku-hanga pioneer who did more than any other Japanese artist to establish abstract woodblock as a serious modern medium. The British Museum holds an impression of this sheet, which is catalogued through ukiyo-e.org. The title alludes to the European anecdote in which Columbus, challenged to make an egg stand upright, taps its base to flatten it, a story used since the Renaissance as an emblem for solutions that are obvious only after the fact. Onchi's treatment of the theme is not narrative but allegorical and formal. The print compresses the motif into a tightly controlled arrangement of shapes and colors in which an egg-like form serves as the focal element within a deliberately constructed pictorial space. The work is characteristic of his Ichimoku-shu contributions, which often paired short literary or philosophical titles with prints that read as visual poems. By taking a European fable as starting point, Onchi also signaled the cosmopolitan reach of the Ichimoku-kai. The First Thursday Society explicitly aligned itself with international modernism, drawing on European symbolism, Expressionism, and abstraction while maintaining a uniquely Japanese command of the woodblock medium. The British Museum's holdings of Vol. 4 sheets document this stage of the group's work and Onchi's continued movement away from representational subjects toward the fully abstract compositions of his late years.
