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 story introduces Gilgamesh, king of Uruk. Gilgamesh, two-thirds god and one-third man, is oppressing his people, who cry out to the gods for help. For the young women of Uruk this oppression takes the form of a droit du seigneur, or "lord's right", to sleep with brides on their wedding night. For the young men (the tablet is damaged at this point) it is conjectured that Gilgamesh exhausts them through games, tests of strength, or perhaps forced labour on building projects. The gods respond to the people's pleas by creating an equal to Gilgamesh who will be able to stop his oppression. This is the primitive man, Enkidu, who is covered in hair and lives in the wild with the animals. He is spotted by a trapper, whose livelihood is being ruined because Enkidu is uprooting his traps. The trapper tells the sun-god Shamash about the man, and it is arranged for Enkidu to be seduced by Shamhat, a temple prostitute, his first step towards being tamed. After six days and seven nights of lovemaking and teaching Enkidu about the ways of civilization, she takes Enkidu to a shepherd's camp to learn how to be civilized. Gilgamesh, meanwhile, has been having dreams about the imminent arrival of a beloved new companion and asks his mother, Ninsun help to interpret these dreams.
