She was beautiful, powerful, and devious – a perfect foil for the ancient serpent’s deceptions. Her husband Nimrod had made himself king over the migrants who came into the new land of Sumeria, a very rich alluvial plain in which things grew quickly, but wild beasts also multiplied and became a constant menace. The people had no weapons and they needed protection. Nimrod invited them to live together in one place and built a wall all around it to protect them. (The points expressed about the background to Nimrod and Semiramis are found in Josephus’ Antiquities of the Jews.)
He became their king, a warrior king who built an army and taught men to make and use weapons, and he led them on profitable hunts to provide meat. Business was good, so he built other cities as populations increased, but he had a problem.
People still worshipped the One true God and looked to Shem, the son of Noah, as the man of God and leader of their faith. Faith was a powerful thing and Nimrod wanted that power, but how would he turn the people’s faith toward himself? His beautiful, scheming wife Semiramis provided the answer. She began to laud her husband Nimrod as their great provider and protector. We don't know exact details, but there are abundant examples in history from which we can draw such conclusions. (Bible verses about Semiramis; Bible Tools.org)
The Devil, that most subtle of deceivers (Genesis 3:1 Genesis 3:1Now the serpent was more subtle than any beast of the field which the LORD God had made. And he said to the woman, Yes, has God said, You shall not eat of every tree of the garden?

Put on the whole armor of God, that you may be able to stand against the wiles of the devil.  For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.

American King James Version×). This gave Satan an in and he cunningly inspired them to worship him as the Sun god, the source of knowledge and of life for all things on Earth. He backed up this idea by performing signs and wonders as people were converted to this new faith. It effectively turned people’s hearts to pleasure and to worshipping their god as they pleased. It was heady stuff and men and women of all kinds responded in droves.
It all made Shem very anxious for the people. He was very angry with the man who had brought about this growing apostasy and he acted at once to execute the self-proclaimed king and high priest of the Sun god. Ultimately, he had Nimrod's body cut in pieces to be distributed to the various civic centers as a dire warning of what would happen to others who had been deceived into forsaking the Creator by worshipping idols and demon spirits. (See Josephus' Antiquities of the Jews).
Semiramis knew better than to openly defy Shem, but developed a mystery religion with herself as high priestess. Her followers used secret signs and symbols so as not to let on. She led them in worship of the god of love and fertility and took many lovers in her conquest of men. She then became pregnant and when she gave birth to Tammuz (meaning ‘son of life’). Semiramis daringly presented him at the Winter solstice as the son of Baal, the long expected Seed of the woman forecast in the Garden of Eden. Most likely everyone on Earth at that time knew the prophecy given to Adam, Eve and the Serpent before they were cast out of Paradise, because Noah and his family spread the gospel after the Flood. Satan used this knowledge to help thwart the coming truth that was to come.
Semiramis also had caused Nimrod to be venerated as a god after his death. She said he was made one with the "Sun in Heaven". She said that her son Tammuz had been supernaturally conceived in her womb by him, thus claiming to be "that" woman. Her child then represented new birth and the possibility of resurrection for all who believed. As the sun regained strength and rose up after the Winter solstice, so would mankind experience rebirth after death. After Tammuz died by being nailed or bound to an evergreen tree, she wailed for him until he was restored to her. Women of many nations thereafter wept for Tammuz, even in Israel. (Ezekiel 8:14 Ezekiel 8:14Then he brought me to the door of the gate of the LORD's house which was toward the north; and, behold, there sat women weeping for Tammuz.

Meanwhile, the men of Babel were busy building a huge tower to reach high into the sky and make them famous and their city the foremost in the world. They planned to stay there in that place and not spread out and replenish and fill the whole earth as God had commanded. The Lord came down to see for Himself what they were up to and saw that they were of one evil mind and working together they would invent and create things far too quickly. People had corrupted themselves before and managed to pollute everything in the old world. They shared only one language, so God miraculously confused their ability to communicate, which forced them to move out in groups, each group bound by a different language and so they went about establishing separate lands of their own.
The small families scattered from Babel and became fully fledged nations, but unfortunately took with them the worship of mother and child as they had learned from Semiramis. Thus began many counterfeit faiths spread around the world and even today cause so much confusion.
Whatever else we might say about the devil, he is industrious and clever in his opposition to God and the only church founded by Jesus Christ. This article simply illustrates some of the basic truths of Revelation 17, especially with regard to mother and child and the whole pantheon of gods and false worship.
Semiramis appears to be the source that started it all in human history, inspired by the devil who backed her up with visions and mirages. It all began more than 2000 years before Jesus Christ was born of Mary and it is no wonder that there are so many pagan parallels with modern Christianity. The counterfeit religion is that of the great deceiver and god of this world who actively blinds mankind to the truth, (2 Corinthians 4:4 2 Corinthians 4:4In whom the god of this world has blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine to them.

History says Nimrod was the first mighty one ‘deified’ after the Flood. He was represented by a winged bull and called the ‘father of the gods’. His wife Semiramis became the ‘mother of the gods’ and Queen of heaven. The characteristics of that initial Chaldean mystery religion which she founded were: rejection of our Creator God, denial of His commandments, refusal to acknowledge Him as the source of all life, and a paranoid desire for self-exaltation – the making of God in man’s image! ‘You shall be as gods’ the Serpent told Eve, but in effect he became their god, the one whom they obeyed. (Romans 6:16 Romans 6:16Know you not, that to whom you yield yourselves servants to obey, his servants you are to whom you obey; whether of sin to death, or of obedience to righteousness?
