Tammuz (deity) in the context of "Ishtar"

Dumuzid or Dumuzi or Tammuz (Sumerian: 𒌉𒍣, romanized: Dumuzid; Akkadian: Duʾūzu, Dûzu; Hebrew: תַּמּוּז, romanized: Tammūz), known to the Sumerians as Dumuzid the Shepherd (Sumerian: 𒌉𒍣𒉺𒇻, romanized: Dumuzid sipad) and to the Canaanites as Adon (Phoenician: 𐤀𐤃𐤍; Proto-Hebrew: 𐤀𐤃𐤍), is an ancient Mesopotamian and Levantine deity associated with agriculture and shepherds, who was also the first and primary consort of the goddess Inanna (later known as Ishtar). In Sumerian mythology, Dumuzid's sister was Geshtinanna, the goddess of agriculture, fertility, and dream interpretation. In the Sumerian King List, Dumuzid is listed as an antediluvian king of the city of Bad-tibira and also an early king of the city of Uruk.

In Inanna's Descent into the Underworld, Inanna perceives that Dumuzid has failed to properly mourn her death and, when she returns from the Underworld, allows the galla demons to drag him down to the Underworld as her replacement. Inanna later regrets this decision and decrees that Dumuzid will spend half of the year in the Underworld, but the other half of the year with her, while his sister Geshtinanna stays in the Underworld in his place, thus resulting in the cycle of the seasons. In the Sumerian poem Inanna Prefers the Farmer, Dumuzid competes against the farmer Enkimdu for Inanna's hand in marriage.
