The purpose of this study is to classify the comparative trait of the oral literature around the area of Incheon. Firstly, as wide-spread legends, I examined those of Agijangsu(아기장수), Jangjamot(장자못), Sanidong(산이동), Dallae(달래). Among them, Agijangsu and Jangjamot have high degree of distribution and many variegated forms. Another types of wide-spread legends have low degree of distribution, as well as being separated from basic forms. Nextly, as regional legends, I examined those of natural things, artifacts, persons and geographical designations, customs and beliefs. In case of natural things, there are many types of tales about rocks, mountains, ponds and springs. Some of them show the traces of regional myths. And the tales about temples, fortifications, and shrines of tutelary deity were inspected as representatives of artifacts. Tales about persons and geographical designations bear a unique regional personality, because they are closely connected with the history and geography of that region. In case of customs and beliefs, the tales about Imkyungup(임경업) and Sondol(손돌) are inspected as representatives, which are entangled in the fishing custom of yellow corvina and the origin of cold weather. The Imkyungup tales has been fixed as regional legends, being added with his prominent wisdom and ability upon his real historical deeds, and being naturally connected with the fishing custom of yellow corvina around the Yeonpyung(연평) island. The Sondol tales express the antipathy of lower classes which is symbolized as a disaster of nature. Finally, I inquired the oral modificational aspects of documentary literature and classical novels such as , , , etc. In those ones, very interesting modificational aspects were found, which are variously modified by the principle of oral transmission and the regional peculiarity.
