Shiji"Volume 14 - Twelve Vassals' Chronology" quote: "魯君子左丘明懼弟子人人異端，各安其意，失其真，故因孔子史記具論其語，成左氏春秋。" Wai's 2013 translation: "A gentleman of Lu, Zuo Qiuming, was afraid that the disciples each had divergent ideas [about the meaning of the Annals], would be satisfied with his own conceptions, and lose the true meaning [of Confucius' messages]. Therefore he based himself on Confucius' scribal records, fully arrayed their words, and completed the Zuo Tradition of the Annals."
Analects "Gongye Chang" 25 quote: "子曰：「巧言、令色、足恭，左丘明恥之，丘亦恥之。匿怨而友其人，左丘明恥之，丘亦恥之。」". James Legge's translation: "The Master said, "Fine words, an insinuating appearance, and excessive respect – Zuo Qiu Ming was ashamed of them. I also am ashamed of them. To conceal resentment against a person, and appear friendly with him – Zuo Qiu Ming was ashamed of such conduct. I also am ashamed of it.""
Kong Yingda, True Meaning of Chunqiu Zuozhuan "vol. 60: Duke Ai's 13th year - zhuan" p. 20 of 146, quote: "傅玄云：《國語》非丘明所作。凡有共說一事而二文不同，必《國語》虛而《左傳》實，其言相反，不可強合也。" translation: "Fu Xuan said: '′Discourses of the States′ was not authored by Qiu Ming. Wherever they both narrate one thing yet their wordings differ, certainly ′Zuo tradition′['s narrative] is authentic while ′Discourses of the States′['s narrative] is spurious. The contradictory wordings cannot be forcibly reconciled.' "

The earliest extant mention of Zuo Zhuan is in Sima Qian's Records of the Grand Historian, where the narrative is named 左氏春秋 Zuǒshì Chūnqiū "Master Zuo's Spring and Autumn";[1][2] thus suggesting that the narrator's lineage surname (氏 shì) was 左 Zuǒ. Zhu Yizun 朱彝尊 (1629-1709) thought that the narrative's author bore a double-character surname 左丘 Zuǒqīu; Yu Zhengxie 俞正燮 (1775-1840) thought his surname is 丘 Qīu, while zuŏ 左 "was the designation of his office", short for zuǒshǐ 左史 "scribe to the left".[3][4]
