This is Adonis and Venus.  Scholars and even my Bible Dictionary all agree that Tammuz is just another form of this Greek god Adonis.  Tammuz's bride is Ishtar, the Goddess of love, just as Adonis' bride pictured here is Venus, goddess of love.  This exact same couple is found in Sumerian, Babylonian, Arabian and Greek cultures.  And in Hebrew because the word Adonai is definitely derived from Adonis.  Adonis, Adonai and Tammuz are all the same Lord God.
