The Titans in Greek mythology are a group of primordial deities, significant for their vast powers and roles in the cosmos. They represent fundamental aspects of the universe, such as ocean (Oceanus), sky (Uranus), and earth (Gaia). The Titans ruled before the Olympian gods and were overthrown by their offspring, symbolizing the transition of power and the ongoing struggle between generational forces. Their significance lies in their embodiment of natural elements and the foundational myths that explore themes of creation, chaos, and the balance of forces.
