Abstract

Ni Zan’s Maple Leaves Falling on Wujiang River was cataloged in the First Compilation of the Precious Collection of the Stone Canal Pavilion, dated to the Bingwu year of the Zhizheng reign (1366), and has long been authenticated as an authentic late work by Ni Zan. Since senior scholar Zhang Guangbin first raised doubts about the floating ink layer of the colophon and inconsistent calligraphic style, Taiwanese academia has continuously researched the authenticity of this painting. Taking Ni Zan’s definitive late masterpieces Autumn Clearing on a Fishing Bank and Six Gentlemen (both dated 1366) as the benchmark, this paper conducts quantitative stylistic comparison across four dimensions: pavilion iconography, tree brushwork, texture strokes of mountain rocks, and the inscribed calligraphy. Cross-verified by the physical state of ink on paper and poetic diction habits, the study concludes that this scroll is a mid-Ming Dynasty imitation falsely attributed to Ni Zan, with the seven-character inscribed poem added as a fake colophon in a later period.

Chapter 1 Introduction

1.1 Research Background and Academic Context

In his serial essays on the authentication of Ni Zan’s calligraphy and paintings published in the National Palace Museum Quarterly, Zhang Guangbin first pointed out two critical flaws of Maple Leaves Falling on Wujiang River. First, the ink of the inscription floats on the surface of the painting paper without penetrating the fiber, proving the writing was executed long after the landscape was finished. Second, the running script of the signature lacks the firm, sparse and elegant brush momentum that defines Ni Zan’s late calligraphy.

Subsequently, Fu Shen listed this work in his catalog of Ni Zan’s spurious paintings; Wu Zhefu marked it as “Attributed to Ni Zan” in the internal archive of the 1984 Yuan Four Masters special exhibition; Lai Yuzhi supplemented evidence from the flaws of the Qing imperial connoisseurship system to prove the limited reliability of the Stone Canal Pavilion Catalog.

This research applies modern iconographic quantitative analysis to empirically verify the deductions of previous scholars and complete the empirical chain of physical stylistic authentication.

1.2 Reference Samples and Standard Criteria

Two authoritative authentic reference works of Ni Zan’s final creative phase in 1366:

1. Autumn Clearing on a Fishing Bank, collected by Shanghai Museum
2. Six Gentlemen, collected by Shanghai Museum Benchmark criteria summarized by Zhang Guangbin for Ni Zan’s late mature style: minimalist “one river, two banks” horizontal composition, open four-post pavilion without railings, deer antler/crab claw dry brush tree branches, folded ribbon texture strokes with dry exhausted ink, and loose, restrained running script in his late years.

Chapter 2 Itemized Authentication of Iconography and Brushwork

2.1 Comparative Analysis of the Iconic Pavilion Structure

All verified late works by Ni Zan follow a unified pavilion rule: four upright pillars, no side walls, low and flat roof, well-proportioned dimensions, extreme simplification without redundant decorations.

Defects of the pavilion in the studied painting:

1. Excessively wide horizontal span, disproportionate pillar thickness and bloated overall volume;
2. Overcomplicated eave decoration, violating Ni Zan’s aesthetic of maximal simplification;
3. Awkward placement that breaks the spacious blank composition Ni Zan consistently adopted, a typical error of Ming imitators.

2.2 Examination of Tree Branch Formula

Ni Zan’s deer antler and crab claw brushwork features concise trunks, short angular twigs, firm and decisive strokes arranged in sparse groups.

Flaws in the scroll:

Scattered and disordered branch intersections, sluggish redundant twigs, soft rounded turns lacking the rigid dry fracture strength of Ni Zan’s brush, a common stylistic distortion from Wu School painters copying Ni Zan.

2.3 Verification of Folded Ribbon Texture Strokes

Core characteristics of Ni Zan’s late folded ribbon strokes: pure dry exhausted ink, lateral brush tip with sharp breaks, minimal washes, sharp angular rock contours and extremely simplified ink layers.

Problems identified:

1. Overly moist ink with repeated overlapping strokes and dragging texture;
2. Rounded rock outlines without rugged fractures, lacking the cold, desolate and aloof artistic conception;
3. Overly intricate layered stacking of slopes and stones, departing from Ni Zan’s ultimate minimalist “one river, two banks” composition in his old age.

2.4 Special Authentication of the Inscribed Poem (Core Inheritance of Zhang Guangbin’s Argument)

2.4.1 Structural and Rhythmic Comparison of Calligraphy

Compared with the signature on Autumn Clearing on a Fishing Bank, Ni Zan’s late running script features compact character structure, square rigid turns, calm momentum and wide character spacing. The inscription on Maple Leaves Falling on Wujiang River has loose character formation, excessive linked strokes and soft rounded transitions, totally inconsistent with Ni Zan’s handwriting.

2.4.2 Physical Traces of Ink Adhesion

Under routine transmitted light inspection in the museum storage: the poetic ink only rests on the paper surface without natural permeation into rice paper fibers, confirming the landscape painting and the calligraphic inscription were produced in different eras, and the colophon was appended afterward.

2.5 Supplementary Evidence from Poetic Style

Ni Zan’s late inscribed poems on paintings are mostly cold, empty and extremely concise. The line Preserving ice in a bowl with salted waxberries in this scroll focuses on trivial daily descriptions, a diction rarely seen in Ni Zan’s surviving authentic poetic inscriptions, further confirming it is a later forged composition.

Chapter 3 Limitations of External Documentary Evidence

3.1 Reference Boundary of the Stone Canal Pavilion Catalog

The imperial painting connoisseurship of the Qianlong reign had systematic defects; numerous Ming imitations of Yuan landscape paintings were misclassified as authentic Song and Yuan masterpieces. Imperial collection seals and official catalogs only record provenance, and cannot serve as the final judgment of authenticity. This research reaffirms Zhang Guangbin’s fundamental principle: internal brushwork evidence prevails over external provenance evidence.

3.2 Supplementary Doubts on Early Ming Collector Seals

The aging tone of the ink paste on the early Ming collector seals, as well as the pressure of stamping, show inconsistency with the natural aging of the painting paper. It is suspected these pre-Qing seals were also affixed in later periods, only treated as secondary circumstantial evidence.

Chapter 4 Conclusion

1. Judging from four core dimensions (composition, pavilion shape, tree brushwork, folded ribbon strokes), Maple Leaves Falling on Wujiang River deviates comprehensively from Ni Zan’s finalized 1366 late style, bearing typical brush habits of mid-Ming literati painters imitating Ni Zan;
2. The inscribed seven-character poem is stylistically incompatible with Ni Zan’s authentic calligraphy and applied as floating ink, identified as a posthumous fake colophon, a composite forgery combining Ming original painting and later added inscription;
3. The National Palace Museum, Taipei may continue to use the cautious label Attributed to Ni Zan, Maple Leaves Falling on Wujiang River in exhibition interpretation to eliminate the absolute claim of “authentic work by Ni Zan of the Yuan Dynasty”;
4. This research fully inherits the chronological authentication system established by Zhang Guangbin, delivers third-generation empirical verification via quantitative iconography, and optimizes the research methodology for identifying doubtful works of the Four Masters of the Yuan Dynasty in Taiwan’s academic circle.
