7세기 초 신라의 對隋 군사외교에 대한 재검토

Reexamination of Shilla’s Military Diplomacy with the Chinese Su(隋) dynasty, in the early 7th century: Focusing on verifying the legitimacy of the Weon’gwang(圓光) Geolsa-pyo(乞師表)

이 논문은 圓光의 乞師表 사적이 후대에 가공된 것이며, 신라의 對隋 請兵 또한 실재하지 않았음을 확인한 것이다. 이는 걸사표를 출발점으로 하는 7세기 신라의 대중국 군사외교에 대한 전면적 재검토의 첫걸음이 된다. 신라의 대수 청병은 『隋書』에는 보이지 않으며, 당시 고구려와 신라의 관계도 청병을 필요로 하는 상황이 아니었다. 원광의 걸사표는 본래 그의 儒學 이해를 보여주기 위해 對唐 청병과 强首의 사적을 모티브로 가공한 것이며, 그의 활동 시기에 맞추어 對隋 청병으로 정리되었다. 그 원전인 신라의 『殊異傳』은 고려에서 金陟明, 朴寅亮 등에 의해 改作 내지 潤 文되었으며, 이 과정에서 불교 계율보다 국가를 우선하는 그의 답변 내용이 생성되어 추가되었다. 『삼국사기』는 백제의 청병 사적에 맞추어 청병과 수 양제의 허락을 608년과 611년에 나누어 넣었는데, 608년은 607년의 편집 오류로 파악된다.

Confirmed in this article is the fact that the story of “Weon’ gwang(圓光)’s Geolsa-pyo(乞師表, the Appeal for a Military Relief)” is actually a false one, fabricated during later periods, and that Shilla never asked the Chinese Su(隋) dynasty for military troops and aid. This new confirmation requires us to reexamine the Shilla dynasty’s history of military diplomacy with the Chinese dynasties in the early 7th century, which has been believed to have initiated with Shilla’s said ask for a Chinese military relief. The supposed fact of Shilla asking the Su dynasty to dispatch military troops cannot be found from Suseo(隋書, The Official History of the Su Dynasty), and considering the relationship between Goguryeo and Shilla at the time, it does not seem likely that Shilla was in need of a foreign military aid. The story of Weon’gwang’s Geolsa-pyo appeal was apparently modeled after the story of Gang Su(强首) who had earlier asked troops from the Chinese Dang(唐) dynasty, and set during his lifetime, in an effort to emphasize Weon’gwang’s expertise in Confucianism. The original text, Shilla’s Su’i-jeon(殊異傳), was rewritten(or supplemented) by Kim Cheok-myeong(金陟明) and Park In-ryang(朴寅亮) during the Goryeo period, and in the process Weon’gwang’s “response” -of a nature prioritizing the state’s welfare than Buddhist teachings- was newly created, and added to the original text. Then, based on this fabricated story, Samguk Sagi documented Shilla’s supposed request for troops as well as Su Emperor Yangje’s authorization of dispatching them, in the entries(years) of 608 and 611 respectively, of which the former seems to be an error of 607.
