A character from Assyrian-Bablyonian myths (notably in "The Epic of Gligamesh"), clearly related to Isis, Venus, Astarte, and other goddesses. The name Ishtar is Semitic (Hebrew), and has been explained as meaning "the self-waterer" (George A. Barton, 1915).
"Mary Magdalene, as well as Salambo, Matres, Ishtar, Astarte, Aphrodite and Venus all represent the priestess-wife with whom we must practice Sexual Magic in order to awaken the fire." - Samael Aun Weor, The Perfect Matrimony
"The myth of Tammuz and Ishtar is one of the earliest examples of the dying-god allegory, probably antedating 4000 B. C. The imperfect condition of the tablets upon which the legends are inscribed makes it impossible to secure more than a fragmentary account of the Tammuz rites. Being the esoteric god of the sun, Tammuz did not occupy a position among the first deities venerated by the Babylonians, who for lack of deeper knowledge looked upon him as a god of agriculture or a vegetation spirit. Originally he was described as being one of the guardians of the gates of the underworld. Like many other Savior-Gods, he is referred to as a "shepherd" or "the lord of the shepherd seat." Tammuz occupies the remarkable position of son and husband of Ishtar, the Babylonian and Assyrian Mother-goddess. Ishtar--to whom the planer Venus was sacred--was the most widely venerated deity of the Babylonian and Assyrian pantheon. She was probably identical with Ashterorh, Astarte, and Aphrodite. The story of her descent into the underworld in search presumably for the sacred elixir which alone could restore Tammuz to life is the key to the ritual of her Mysteries. Tammuz, whose annual festival took place just before the summer solstice, died in midsummer in the ancient month which bore his name, and was mourned with elaborate ceremonies. The manner of his death is unknown, but some of the accusations made against Ishtar by Izdubar (Nimrod) would indicate that she, indirectly at least, had contributed to his demise. The resurrection of Tammuz was the occasion of great rejoicing, at which time he was hailed as a "redeemer" of his people.
"With outspread wings, Ishtar, the daughter of Sin (the Moon), sweeps downward to the gates of death. The house of darkness--the dwelling of the god Irkalla--is described as "the place of no return." It is without light; the nourishment of those who dwell therein is dust and their food is mud. Over the bolts on the door of the house of Irkalla is scattered dust, and the keepers of the house are covered with feathers like birds. Ishtar demands that the keepers open the gates, declaring that if they do not she will shatter the doorposts and strike the hinges and raise up dead devourers of the living. The guardians of the gates beg her to be patient while they go to the queen of Hades from whom they secure permission to admit Ishtar, but only in the same manner as all others came to this dreary house. Ishtar thereupon descends through the seven gates which lead downward into the depths of the underworld. At the first gate the great crown is removed from her head, at the second gate the earrings from her ears, at the third gate the necklace from her neck, at the fourth gate the ornaments from her breast, at the fifth gate the girdle from her waist, at the sixth gate the bracelets from her hands and feet, and at the seventh gate the covering cloak of her body. Ishtar remonstrates as each successive article of apparel is taken from her, bur the guardian tells her that this is the experience of all who enter the somber domain of death. Enraged upon beholding Ishtar, the Mistress of Hades inflicts upon her all manner of disease and imprisons her in the underworld.
"As Ishtar represents the spirit of fertility, her loss prevents the ripening of the crops and the maturing of all life upon the earth.
"In this respect the story parallels the legend of Persephone. The gods, realizing that the loss of Ishtar is disorganizing all Nature, send a messenger to the underworld and demand her release. The Mistress of Hades is forced to comply, and the water of life is poured over Ishtar. Thus cured of the infirmities inflicted on her, she retraces her way upward through the seven gates, at each of which she is reinvested with the article of apparel which the guardians had removed." - Manly P Hal, The Secret Teachings of All Ages
