Inanna's Descent to the Netherworld

An important piece of Mesopotamian Mythology, and one of the oldest written stories. The story is about the goddess Inanna (later known as Ishtar) going to visit her sister (or possibly alter-ego) Ereshkigal.

Tropes in Inanna's Descent to the Netherworld include:

 * Back From the Dead: Inanna, and later Dumuzi.
 * Crazy Prepared: Inanna anticipates problems, and instructs her priestess exactly what to do.
 * Dark Is Not Evil: Ereshkigal seems mostly portrayed this way.
 * Death Glare: Literally causes death.
 * Evil Twin: Though it is not entirely clear which one is the evil one. See below.
 * Expy: Ereshkigal is a Darker and Edgier version of her younger twin, Inanna. Some scholars believe they were at one point two aspects of the same goddess before becoming separate entities.
 * Faux Action Girl: Inanna.
 * The Glorious War of Sisterly Rivalry
 * I Lied: Inanna clearly was not there for the purpose of Gugalana's funerary rites.
 * Just-So Story: Explains why we have winter and summer.
 * The Long List: See "Oral Tradition".
 * MacGuffin: Asu-shu-namir, the asexual creatures that help Inanna be brought back to life.
 * My God, What Have I Done?: After Inanna's fury subsides and she realizes the horrible consequences of sicking demons after her husband, she weeps.
 * Not So Different: Inanna and Ereshkigal. In fact, Ereshkigal might actually be a Darker and Edgier Expy of Inanna. This is further supported by the interesting thematic relation of the husbands of both women dying in the story as bookends, as well as the link-up between this story and the story where Gilgamesh kills Inanna's bull of heaven (the exact same bull that is the husband of Ereshkigal).
 * Oral Tradition: The story was clearly this before it was recorded, as evidenced by the repetition.
 * Our Demons Are Different: The closest approximation is the Hollows of Bleach fame.
 * Out-of-Clothes Experience: Inanna is stripped of her clothing and jewelry (symbols of her power) to grovel before Ereshkigal.
 * Pimped-Out Dress
 * Power, Dear Boy: Inanna. Her reason for going to Irkalla in the first place? She wants dominion over the heavens, Earth, and the underworld, and everything there. She actually gets it, too, though not in the exact way she wanted it and at some great cost.
 * The Powers That Be
 * Rescue: Inanna anticipates problems, and instructs her priestess what to do. The priestess and another deity end up going to rescue Inanna.
 * Screaming Birth: After having killed Inanna, Ereshkigal is implied to be in a sort of crazed, emptiness-induced state of mental breakdown that resembles a very violent labor.
 * Spin-Off: Takes place just after Gilgamesh and his friend kill Gugalana (The Bull of Heaven) in The Epic of Gilgamesh, but is considered its own separate story.
 * Take Me Instead!: When Dumuzi is sent to the Underworld in Inanna's place, his sister begs Inanna to let her go instead.
 * To Hell and Back: One of the oldest stories of this type; possibly even the Ur Example
 * What the Hell, Hero?: Dumuzi gets one of these for not saliently mourning his wife.
 * Yandere: Inanna has her husband, Tammuz/Dumuzid, dragged off to the Underworld for cheating on her while she was dead. Gilgamesh even lists this as one of her defining character traits when refusing her affections, even citing what she did to Tammuz as an example. - which doesn't quite make sense if this myth is set after The Epic of Gilgamesh.
 * Zombie Apocalypse: Inanna uses this threat against the gatekeeper if he does not let her in.
