Definition & Meaning of "styx"

What is "Styx"?

Styx is a river in Greek mythology that forms the boundary between the world of the living and the realm of the dead. It is often depicted as a dark, flowing river that souls must cross to enter the afterlife. According to myth, Charon, the ferryman, transports souls across the Styx, but only those who have received proper burial rites may make the journey. The river is also associated with oaths and promises, as gods would swear by the Styx, making it a powerful symbol of loyalty and consequence.
