Science that has developed to this day seems to shift the role of the logic of Theo-logos, namely science that is still supported by divine values or religion. Before humans recognize the logic of science as a tool to understand truth, humans initially seek truth by using mythical logic so that myth is called pre-logic. Between myth and science or logos has the same role, which is to be an answer to chaos in understanding a natural phenomenon. One of the pre-logical phenomena is found in literary works of various myths or legends. Some of them are the myth of Watugunung and the legend of Sangkuriang. Both works are urgently studied in the comparative literature study paradigm, because they contain the same substance, namely the incest and symbolism of the siwaistic understanding of the archipelago. The focus of the issue that will be discussed in this study is how is sexual relations in the Watugunung Myth and Sangkuriang Legend as theological symbolization? This problem was assessed using structural and semiotics theory while, the research method used a qualitative paradigm with the type of data in the form of narration or discourse in the medium of language. The primary data source is the text of the Medang Kemulan Manuscript and the printed text of the Sangkuriang Manuscript. The theological symbolization in the myths of Watugunung and the legend of Sangkuriang there are several symbols, namely: (a) Phaulus as a symbol and understanding of Shiva, (b) Symbol of fertility due to meeting lingga with yoni, (c) Symbol of Wealth, (d) Symbol of awareness of sexuality, (e ) Symbol of awareness of time, (f) Symbol of awareness of the holy place. While symbolizing the theological meaning in Sangkuriang, namely: (a) Mountain as a symbol of Shiva, (b) Symbol of unification of mountains with lake water (lingga and yoni), (c) Symbols of sexual awareness, and (d) Symbol of awareness of time and place.
