Overarching themes that connect the cycle of life, death, and rebirth in mythology include transformation, renewal, and resilience. Many myths illustrate this cycle through narratives of gods dying and being reborn, such as Osiris in Egyptian mythology. These themes reflect the natural cycles observable in nature, symbolizing the inevitability of change and the continuance of life. Additionally, such narratives serve to offer hope and a sense of purpose, reinforcing the idea that death is not an ending but rather a transition towards new beginnings.
