This paper will focus on bicorporates, the enigmatic composite animals with one head and two bodies which have been left rather outside of scholastic attention. The first known bicorporates appeared on Mesopotamian cylinder seals around the third millennium BCE. They subsequently appeared in Minoan, Greek, Etruscan and Roman art. In mediaeval Europe, they flourished in Romanesque churches, especially, Southern Europe and Scandinavia. Furthermore, they also emerged in India and Southeast Asia and China. Bicorporates exist across a remarkably wide geographical and (...) chronological range. Even though a small number of scholars carried out some research on them, most of their focus was trying to trace the migration route of the images. No previous study had focused on answering the most intriguing question, how these enigmatic images came about and the reason why they spread and recurred beyond geographical and chronological borders. Therefore, this paper will focus on the questions and seek to provide the answers, by applying neuropsychological reading and analytical psychology. The findings of this study suggest that Lewis‐Williams' neuropsychology and Jung's analytical psychology are intertwined and both offer explanations for the origin and widespread occurrence of bicorporate images. However, the contrast between these two theories lies in the fact that Lewis‐Williams' theory relies on the perspective of materialistic science, implying that these images are solely products of the human brain and nervous system. In contrast, Jung's theory allows for the possibility of exploring the invisible or esoteric realm, which cannot be disproven or proven by current materialistic science. (shrink)
