Dèng Guāngjiàn 鄧光薦 (1232–1303), originally named Dèng Yìshēng 鄧剡 (zì Zhōngfǔ 中甫, hào Zhōngzhāi 中齋), was a late-Sòng official, literatus, and patriot, native of Lúlíng 廬陵 (Jiāngxī). He earned his jìnshì 進士 in Jǐngdìng 3 (1262) and rose to relatively high rank in the Sòng administration. After the fall of the dynasty he twice unsuccessfully attempted suicide, and refused to respond to the overtures of the Yuán general Zhāng Hóngfàn 張弘範. He was for a time a captive of the Yuán, taken north along with the Sòng courtier Wén Tiānxiáng 文天祥 (1236–1283), to whom he was close — and on whose death he wrote a major eulogistic biography (Wén Chéngxiàng zhuàn 文丞相傳) and tomb inscription. Dèng died in 1297 (CBDB) or 1303 (the figure given by Schipper & Verellen) in retirement from public life.
His preface to Zhào Dàoyī’s [[KR5a0308|Lìshì zhēnxiān tǐdào tōngjiàn 歷世真仙體道通鑑]] (DZ 296), dated jiǎwǔ 1294, presents the work as the Daoist counterpart to Sīmǎ Guāng’s Zīzhì tōngjiàn 資治通鑑; it is paired with a colophon by his Lúlíng compatriot 劉辰翁 劉辰翁 (1232–1297). His other works — Wénxín diāolóng 文心雕龍 commentary, Cháoyě yízhèng 朝野遺政 — are largely preserved through scattered citation. The CBDB death year of 1297 differs from the 1303 given in modern reference works (followed in the present catalog frontmatter); the discrepancy hangs on which of two attested obituary notices is preferred.
