Why does Medusa was beheaded by Perseus yet her head continued to have power?

Medusa was beheaded by Perseus as part of a quest to obtain her head, which had the ability to turn anyone who looked at it into stone. Even after her death, her head retained its petrifying power, symbolizing the enduring nature of her curse and the theme of transformation in Greek mythology. Perseus used the head as a powerful weapon, demonstrating that even in death, Medusa's influence remained significant. Ultimately, her severed head served both as a tool for protection and a reminder of the consequences of the gods' actions.
