본고는 石潭 李潤雨(1569~1634)가 그 스승 寒岡 鄭逑(1543~1620)의 학문적 토대가 되는 ‘寒岡學派’의 기반 조성에 대하여 고찰한 논문이다. 이윤우는 21세 때 한강 정구에게 학문하는 방법을 배운 후로 스승을 평생 존경하였다. 스승 사후에 이윤우는 정구에 대하여 贈職·贈諡의 계청, 신도비명 청탁, 천곡서원과 회연서원의 제향 노력 등 주목할 만한 추숭 사업을 실현하였고, 또 스승의 언행록 편찬, 遺文 정리 등 제자로서 책무를 다하였다. 한강학파 기반 조성과 관련하여, 이윤우가 담양부사 재임 당시 스승의 저술 『오선생예설』과 『오복연혁도』를 간행한 것은, 평소 한강 정구의 간곡한 소망에 따른 실천이었다. 예학을 중시했던 조선 시대에서 이 책은 남인·노론·소론 모두가 주목하여 내용을 인용하거나 책을 重刊하였으니, 이윤우가 스승의 위상을 높이는데 크게 기여하였다. 한강학파 기반 자료를 검토한 결과, 『사빈서재식기안』은 이윤우가 주도하여 작성한 것으로 추정하였다. 이 자료에서는 1617.2.16.부터 스승을 모시고 강학하여 7.20.까지 유지되었는데, 강학 문인은 85명이고, 서재에 머물며 아침저녁으로 식사할 때는 날짜별로 서명을 하였다. 서재의 문인들이 봉산[동래]에 목욕 행차를 계획하여 그해 7월 20일 실행하였고, 85명 중 44명이 동참하거나 환송하였다. 「봉산욕행록」은 이윤우가 지은 것으로, 1617.7.20.~ 9.5.까지의 일기이다. 현재 알려진 책으로는 『석담집』(목판본)에 실린 「봉산욕행록」, 1912년 정재기가 간행한 『한강선생봉산욕행록』(檜淵本), 광산이씨가 1908년에 간행한 「한강선생봉산욕행시일기」(光山李氏本) 등 3종인데, 이번에 새로 『석담집』 定稿本을 발견하였다. 정고본 중심으로 비교해 보니, 「봉산욕행록」은 3종 모두 『석담집』의 내용을 저본 삼아서 편성하였다. 『석담집』 목판본은 정고본에서 29.7%를 刪削한 것이었다. 회연본은 내용이 풍부한 편이었다. 『석담집』 정고본과 비교해 보니, 내용의 추가와 산삭이 많았다. 추가된 내용은 시문, 인명, 후대의 관점에서 부정적으로 볼 수 있는 내용 등인데, 대부분 『석담집』 初稿本에 기록되어 있었을 것으로 추단하였다. 그리고 광산이씨본에서는 인명의 增損과 일부 오탈자가 있었다. 「사빈호상록」은 『석담집』에 실려 있는데 1620년 1월 5일 한강 정구가 별세하자 제자 이윤우가 護喪을 맡아서 상례를 처리한 것으로, 소상때까지의 일기이다. 현재 널리 전하는 『석담집』(목판본)을 이번에 발견된 『석담집』(정고본)과 비교하니, 내용 23.7%가 산삭된 것이었다. 기록된 인명은 115명이었고, 단체 인원까지 포함하면 166명(중복 포함)이며, 전체 문상객의 인원수는 1,626명으로 확인되었다. 이윤우는 어떤 행사나 모임이 있을 때 참석자 명단을 작성하였다. 「봉산욕행록」에 통도사 동화록 16명, 포석정 회고록 43명, 이수 동화록 44명, 식송정 회록 31명, 경산 追來者 명록 47명 등 181명 외에 「사빈호상록」115명, 『사빈서재식기안』 85명 등 포함 총 381명(중복자 포함)으로 확인되었다. 이들 명록은 한강학파의 기반[토대] 자료가 될 것이며, 한강학단의 결속적인 인적 네트워크를 구축할 수 있을 것이다.

This article examines the academic basis Seokdam(石潭) Yoonwoo Lee(李潤雨) had of his teacher, Han Gang(寒岡) Gu Jeong(鄭逑), which established the foundation of Han Gang School. Yoonwoo Lee fulfilled several posthumous honorary projects for his teacher including acts of religious services at Cheongok Confucian Academy(川谷書院) and Hwoeyeon Confucian Academy(檜淵書院), the request for funerary monument, and requests to the king for jungjik(贈職), and jungshi(贈諡). In addition, he fulfilled his duties as disciple, such as publication of his teacher’s deeds and organizing Confucian texts. Regarding the foundation of Han Gang School, Yoonwoo Lee’s publications of his teacher’s writings during the time of his working as a head of Damyang Province(潭陽府使), “Ohseonsaengyaeseol”(五先生禮說) and “Ohbokyeonhyeokdo”(五服沿革圖), were acomplishments in accordance with Gu Jeong’s earnest wishes. Those books were attractive to all of Namin, Noron These books were attractive to all of the Namin, Noron, and Soron confucian scholars in the Joseon Dynasty. Moreover, the contents were actively citied or used to the publication of a new edition. Based on these achievement, Yoonwoo Lee greatly contributed to the enhancement of his teacher’s honor. By reviewing the foundational materials of Han Gang School, it was shown that “Sabinseojaesikgian”(泗濱書齋食記案) was led to be written by Yoonwoo Lee. In these materials, it described how he pursued studies with his teacher from February 16th and maintained it until July 20th of 1617, with 85 writers who were also pursuing studies, living in the library and signing their name by date when having their morning and evening meals. These writers in the library planned a bath trip to Bongsan(Dongrae) and, on July 20th of that year, 44 of the 85 people participated or were seen off. “Bongsanyokhengrok”(蓬山浴行錄) was a diary written by Yoonwoo Lee from July 20th to September 5th of 1617. Three books about Han Gang were previoulsy known: “Bongsanyokhengrok,” included in the woodblock printed edition of the “Seok Dam Jip”(石潭集), the Hwoeyeon edition of “Bongsanyokhengrok of Teacher Han Gang” published by Jaegi Jeong(鄭在夔) in 1912, and “Bongsan Bathing Diary of Teacher Han Gang” by the Gwangsan Lee family in 1908. However, a Jeonggo edition of the “Seok Dam Jip“ was newly discovered at this time. A comparison based on the Jeonggo edition(定稿本), it is clear that the “Bongsanyokhengrok” was organized as an original copy with the content of the “Seok Dam Jip” across all the three books. 29.7% of unnecessary writing in the woodblock printed edition of the “Seok Dam Jip” was erased(刪削) in the Jeonggo edition. The content of the Hwoeyeon edition was seemed to be rich. When compared to the Jeonggo edition of the “Seok Dam Jip,” there were many instances of added content or deletions of unnecessary contents. It included content that lines of poetry, descriptions of human life, and those could be viewed negatively from the perspective of future generat and so on; it was concluded that most of them were recorded in the Chogo edition(初稿本) of “Seok Dam Jip.” In addition, there were partial counting errors(增損) of names and typos in the edition of Gwangsan Lee family. “Sabinhosangrok”(泗濱護喪錄) was published in the context of “Seok Dam jip” and was the diary of disciple Yoonwoo Lee until he became the organizer of the first memorial day ceremony and took charge of the funeral service and rituals upon the death of Han Gang Gu Jeong on January 5th of 1620. Comparing the widely distributed woodblock printed edition of “Seok Dam Jip” with the newly discovered Jeonggo edition of “Seok Dam Jip”, 23.7% of the content was deemed unnecessary and deleted. The counted records of condolers were 115 people, and including group members reached 166 people(included duplicates). The total number of mourners was 1,626. Yoonwoo Lee made lists of attendees in certain events or meetings. In the “Bongsanyokhengrok,” 181 people were mentioned, including 16 people in the “Tongdosa Donghwarok”(通度寺 同話錄), 43 people in the “Poseokjeong Hwoego Book”(鮑石亭 懷古錄), 44 people in the “Isu Donghwarok”(二水 同話錄), 31 people in the “Shiksongjeong Hwaerok” (植松亭 會錄) and 47 people in the “Gyeongsan Churaejamyungrok”(慶山 追來者名錄). A total of 381 people(included duplicate people) were identified, including 115 people from “Sabinhosangrok” and 85 people from “Sabin seojaesikgian.” This list of names proposed in this research will be the groundwork or foundational materials for studying Han Gang, and could contribute to establish a cohesive social network for a Han Gang studying group.
