In mythological tales, siblings often play critical roles that reflect themes of rivalry, loyalty, and support. Relationships between siblings can drive the plot, as seen in tales where one sibling may embody traditional virtues while another represents chaos or betrayal. These dynamics not only highlight familial bonds but also reveal deeper societal values regarding family allegiance, the weight of expectations, and individual agency. The portrayal of siblings can be used to explore larger themes of conflict and resolution within a culture.
