Lù Jī 陸機 (261–303), zì Shì héng 士衡, native of Wújùn Huátíng 吳郡華亭 (modern Sōngjiāng 松江, Shànghǎi), was the elder of the Èr Lù 二陸 brothers and the foremost Western-Jìn fù-poet and literary theorist. Grandson of the great Wú general Lù Xùn 陸遜 (the victor of Yílíng 夷陵 / Xiāotíng 猇亭, 222) and son of Lù Kàng 陸抗, who held Wú’s western frontier against Jìn until his death in 274. After the Jìn conquest of Wú in 280, Lù Jī (then 20 sui) and his younger brother Lù Yún 陸雲 retired for nearly a decade to Huátíng before traveling north to Luòyáng (太康末, ca. 289), where they were welcomed by Tàicháng Zhāng Huà 張華 with the famous remark “the conquest of Wú yielded two paragons” (fá Wú zhī yì lì huò èr jùn 伐吳之役利獲二俊).
Lù Jī rose to Píngyuán nèishǐ 平原內史 under the Western Jìn but was caught in the Bā wáng zhī luàn 八王之亂 (War of the Eight Princes); appointed general by Sīmǎ Yǐng 司馬穎, defeated at Hèqiáo 鶴橋 (303), denounced by his subordinate Lú Zhì 盧志, and executed by Sīmǎ Yǐng with his two sons. His final words — sighing that he would never again hear the cranes of Huátíng (Huátíng hè lì qǐ kě fù wén hū 華亭鶴唳豈可復聞乎) — became a canonical lament for compromised political ambition. Standard biography in Jìn shū 54. His writings survive in KR4b0006 Lù Shìhéng wén jí 陸士衡文集; the celebrated Wén fù 文賦 leads that collection. The homonymous Lù Jī 陸璣 (3rd c.) of the Máo shī cǎo mù niǎo shòu chóng yú shū 毛詩草木鳥獸蟲魚疏 is a different figure (different graph, different work).
