Abstract
The purpose of this paper is to report a newly discovered book whose title is Ikkam (翼鑑) and prepare for a full-scale study. The book, Ikkam, has a variety of contexts in which it seems to be written by Park Ji-won. First, 'Sanin' in 'Yeonam-Sanin' is consistent with the behaviors of Yeonam Park Ji-won who lived in hiding in the Yeonam valley in 1777. In addition, many statements written in the introduction, such as "as we stick to the old things, we do not know a makeshift", "we are well versed in changes" and "many soldiers are not always good" remind us of other writings of Park Ji-won. Moreover, he writes the statements using antithesis. It is the force of writing style of a literary person who is not engaged in medical service. In addition, he puts six qi in the introduction, but it is not as sophisticated as Jejungsinpyeon (濟衆新編). It suggests that this book may be published earlier than Jejungsinpyeon. When comparing Ikkam with Euimunbogam (醫門寶鑑) and Jejungsinpyeon, it seems common to place six qi in the introduction at the time. In addition, through this book, we find that Park Ji-won known as a writer of Geumryosocho (金蓼小抄) has fairly much knowledge in the medicine. We can estimate his passion and depth about the medicine through a longing for a new medical book shown in the introduction of Geumryosocho. However, various approaches to similar disease symptoms shown in the introduction help us to recognize his true qualities in the medicine. In addition, like other experience prescriptions, this book excludes prescriptions using medicinal herbs with toxicity or rare medicinal herbs in the situation with a limited supply of them in remote areas but includes prescriptions which are widely used. It shows that experience prescriptions in the Joseon Dynasty are effective to specifically identify medicinal herbs and prescriptions which are widely used in Korea. These values cannot be compensated by Donguibogam (東醫寶鑑) which has an infinite value.
