19세기의 호남 실학자 李田靑의 『井觀編』 저술과 서양 천문학 이해

Abstract

Yi Cheong (1792-1861) was an unique disciple who had a high degree of scientific knowledge on Astronomy, and Jeong-Gwan-Pyeon was also the unique and unusual book, written by Yi Cheong alone, dealing with comprehensive and a high degree of Astronomy among Great Sirak scholar, Jeong Yagyong school. Because Jeong Yagyong did not write any comprehensive book on Astronomy, this book was expected to show Jeong Yagyong school"s scientific knowledges and discourse on Astronomy.

In this paper, I showed Yi Cheong was the scholar between Choi Han-gi, natural philosopher, and Nam Byeong-cheol, Astronomical-mathematician, who had a high degree of Astronomical knowledge. Jeong-Gwan-Pyeon, however, was the exceptional comprehensive book on Astronomy among Jeong Yagyong school. His great work was due to two causes. one was that he was well-disciplined by Jeong Yagyong in the ages of his early life in his home town, Gang-jin. The other was that he made good friends in Seoul. His friends in Seoul were competent Astronomical-mathematician and the greatest book-collector in Nineteenth Century Joseon Korea. He could not write Jeong-Gwan-Pyeon without his friend"s supports.
