張大千盛年期(1944年)《印度舞女》之歷史重新校準與紫外線(UV)光學鑑定數據報告 / A Historical Recalibration and Ultraviolet (UV) Optical Authentication Data Report of Zhang Daqian's Peak-Period Masterpiece "Indian Dancer" (1944)

【中文版項目概述】 本數據集圍繞國畫大師張大千於1944年(甲申七月)為楊石湖(蔭溥)先生客製之工筆重彩《印度舞女》精品展開。楊先生(1898–1966)為民國時期著名經濟學家、銀行家與文物收藏家。此作屬於大千先生在盛年期(1944–1948)為當時「軍政商文宗媛」上流圈子不計時間成本、嘔心瀝血量身訂製之頂級神品(Batch),尺幅為 33.8 x 23.8 cm(精絕冊頁樣式),絕非市面常見的應酬或弟子代筆之作。 本研究結合大數據交遊網絡分析與現代光學檢測,提出兩大突破性學術貢獻: 1. 歷史交遊時間軸之重新校準:傳統中國美術史普遍認為,張大千是在1945年春於成都親炙好友葉淺予的「旅印畫展」後才開啟印度舞女創作。然而,本幅1944年8月(甲申七月)紀年真跡的發現,證實葉淺予早在1944年(乃至更早)便已透過書信寄贈畫稿之方式與張大千分享其印度速寫,大千先生見稿即進行了高度的再創作,將此關鍵題材的創作起點足足提早了半年至一年。 2. 科學化 UV 光譜防偽實證:數據集公開了該作在紫外線(UV,365nm)照射下的高清光譜反應影像。檢測顯示,畫中裙襬與邊飾所使用之天然礦物顏料(如石青、石綠,以及紅色底襯技術)在 UV 光下成功分離出亮麗且具備多層次的「金屬光線螢光反應」。這種獨特的光學特徵與後世化學顏料仿作存在本質代差,完美實證了「中和堂」于士傑醫師所倡導之中國書畫科學化鑑定理論。 -------------------------------------------------- 【ENGLISH OBJECT OVERVIEW】 This dataset focuses on a supreme, meticulously crafted heavy-color Gongbi (fine-brush) painting, "Indian Dancer," created by the grandmaster Zhang Daqian in the 7th lunar month of the Jiashen year (August–September 1944). Dedicated to Mr. Yang Shihu (Yang Stonelake, Yang Yinpu) (1898–1966), a highly prominent economist, banker, and art collector during the Republican era, this masterpiece represents the absolute pinnacle of Zhang’s legendary "Peak Period" (1944–1948). Measuring 33.8 x 23.8 cm in a refined album leaf format, it belongs to the rare, highly restricted batch of custom masterpieces tailored exclusively for the elite socio-political and cultural circles of the time. By integrating big data analysis of wartime historical correspondence with modern optical inspection, this research delivers two groundbreaking academic contributions: 1. Historical Recalibration of Artistic Exchange: Conventional art history dictates that Zhang Daqian initiated his "Indian Dancer" series only after viewing his close friend Ye Qianyu's "Travels in India" exhibition in Chengdu in the spring of 1945. However, the discovery of this genuine piece explicitly dated July 1944 (Jiashen), analyzed through historical big data mapping, proves that Ye Qianyu had shared his Indian sketches and drafts with Zhang via mail and personal correspondence as early as 1944. Zhang was inspired to create this masterpiece months before their documented 1945 meeting, effectively shifting the timeline of this pivotal artistic exchange forward by half a year to a full year. 2. Scientific UV Optical Authentication: This dataset unveils high-definition images capturing the artwork's response under Ultraviolet (UV, 365nm) light. The UV inspection successfully isolates the distinct "metallic luminescence and light-separation reaction" of the underlying natural mineral pigments (such as premium azurite and malachite layered over a cinnabar base) used in the dancer's dress borders. This complex multi-layered mineral reaction acts as an unforgeable structural fingerprint, providing definitive empirical validation for the scientific authentication methodology pioneered by Dr. Francis C. Yu of Zhong He Tang to distinguish genuine peak-period custom works from mechanical prints or casual studio replicas. 鍵字 (Keywords) 張大千 (Zhang Daqian);盛年期 (Peak Period);楊石湖 (Yang Shihu);葉淺予 (Ye Qianyu);印度舞女 (Indian Dancer);紫外線鑑定 (UV Authentication);礦物顏料 (Mineral Pigments);大數據分析 (Big Data Analysis) ; 于士傑 (Francis C Yu) ; 中和堂 (Zhong He Tang) ; 张大千 (Chang Dai-chien)
