what is the relation between kuber and ravan in mythology
Kubera Originally described as the chief of evil spirits in Vedic-era texts, Kubera acquired the status of a Deva (god) only in the Puranas and the Hindu epics. The scriptures describe that Kubera once ruled Lanka, but was overthrown by his demon half-brother Ravana, later settling in the city of Alaka in the Himalayas. Descriptions of the "glory" and "splendours" of Kubera's city are found in many scriptures.
Epic of Gilgamesh The first half of the story discusses Gilgamesh, king of Uruk, and Enkidu, a wild man created by the gods to stop Gilgamesh from oppressing the people of Uruk. After Enkidu becomes civilized through sexual initiation with a harlot, he travels to Uruk, where he challenges Gilgamesh to a test of strength. Gilgamesh wins and the two become friends. Together, they make a six-day journey to the legendary Cedar Forest, where they plan to slay the Guardian, Humbaba the Terrible, and cut down the sacred Cedar.[1] Later they kill the Bull of Heaven, which the goddess Ishtar sends to punish Gilgamesh for spurning her advances. As a punishment for these actions, the gods sentence Enkidu to death.
