In the myth, the elder brother is friendly and stable, while the younger sibling is decisive and dynamic. Thus the elder brother is the stabilizing force, while the younger brother is the innovating force. These role assignments also reflect the tension between cooperation and conflict in their relationship.
神話中，哥哥是和善的、安定的，弟弟則是具有決斷力和行動力的，所以維持既有部落安定的通常是哥哥，而開創部落的卻是弟弟；這種角色的設定，也同時隱含兩者之間的關係存在著某種「合作又競爭」的張力。
