Various mythological traditions depict mythical creatures that guard the underworld, embodying themes of fear, protection, and the afterlife journey. In Greek mythology, Charon acts as the ferryman who transports souls across the River Styx, while Cerberus, a three-headed dog, guards the gates of Hades. In Egyptian mythology, the devourer Ammit consumes the hearts of the unworthy. Similarly, in other cultures, creatures like the Yama of Hindu mythology serve similar purposes. These guardians highlight cultural beliefs surrounding death and the afterlife, illustrating how societies conceptualize the transition between life and the realm of the dead.
