Geshtinanna combines the Sumerian geshtin (grapevine) and anna (of heaven). **The Sumerian goddess of dream interpretation, poetry, and writing** — sister of Dumuzi (Tammuz). **When her brother was carried off to the Underworld in Inanna's stead, Geshtinanna volunteered to spend half each year there in his place** — establishing the cycle of the seasons.
Featured in Inanna's Descent and the Dumuzi cycle.
Geshtinanna reduces to five — the number of Sumerian seasonal goddess.
