According to folklore, Easter, recognized under various names like Ishtar, Astarte, Ashtoreth, Semiramis, and Biblically the one revered by idolaters as the “queen of heaven” in Jeremiah 7:18; 44:17–25, is commonly believed to be the widow of Nimrod, who was the first on earth to be a mighty and powerful man (see Genesis 10:8–9), and the mother of Tammuz. She is portrayed as a Pagan fertility goddess, often depicted bare-breasted, originating from the east. The legend describes her descent from heaven within a giant egg, landing in the Euphrates River during sunrise on the first Sunday following the vernal equinox. It is said that upon emerging from the egg, she transformed a bird into an egg-laying rabbit.
To honour this event, Pagan sun worshippers would gather early in the morning and face eastward to witness their sun-god's rise over the horizon (see an example of this in Ezekiel 8:16). Following this, they would partake in a mass ritual, often involving sacrifices. In these ceremonies, the priests of Easter would impregnate young virgins on the altar at sunrise on Easter Sunday. The following Easter, the priests would sacrifice these now three-month-old babies and dye the eggs of Easter in their blood. These blood-red-coloured Easter eggs were believed to hatch on December 25th, the same day as the birth of her son Tammuz, considered the reincarnate sun-god, and the traditional winter solstice. This December 25th celebration underwent a process of Christianisation, being recognized today as "Christmas" or Xmas.
According to folklore, following on from the death of Nimrod, his now widowed wife and queen Semiramis (Easter) married and entered into a sexual relationship with her son Tammuz, whom she deified as the reincarnate sun-god. Tammuz met his demise while hunting wild pigs, fatally gored by a boar. This is purportedly the origin of the tradition of consuming ham on Easter among Pagans. Additionally, Tammuz's death at the age of forty led Pagans to observe a fast, allegedly lasting one day for each year of his life. This is likely the Biblically mentioned practice of "weeping for Tammuz" (see Ezekiel 8:14). In Catholic tradition, this fasting period is referred to as Lent.
There is no mention of Easter in the Bible, nor is its celebration mandated. These holidays are ancient Pagan feasts that were ushered in by the Roman Catholic church during the reign of Emperor Constantine. Constantine was a Pagan follower of the sun-god Mithra who had what he thought was a "Christian experience" that led him to victory in battle. He aimed to unify his empire, encompassing both Christian and Pagan populations, under a single, universal (Catholic) religion. To accomplish this, he assimilated ancient wisdom and spiritual elements from various cultures and beliefs. This involved revising historical narratives and assigning Christian names to previously Pagan festivities, beginning at the Council of Nicaea in 325 AD.
The LORD God hates worship in this way. As it is written,
"When the LORD your God cuts off before you the nations whom you go in to dispossess, and you dispossess them and dwell in their land, take care that you be not ensnared to follow them, after they have been destroyed before you, and that you do not inquire about their gods, saying, 'How did these nations serve their gods?--that I also may do the same.' You shall not worship the LORD your God in that way, for every abominable thing that the LORD hates they have done for their gods, for they even burn their sons and their daughters in the fire to their gods. "Everything that I command you, you shall be careful to do. You shall not add to it or take from it. (Deuteronomy 12:29-32 ESV)
Thus says the LORD: "Learn not the way of the nations, nor be dismayed at the signs of the heavens because the nations are dismayed at them, for the customs of the peoples are vanity. A tree from the forest is cut down and worked with an axe by the hands of a craftsman. They decorate it with silver and gold; they fasten it with hammer and nails so that it cannot move. Their idols are like scarecrows in a cucumber field, and they cannot speak; they have to be carried, for they cannot walk. Do not be afraid of them, for they cannot do evil, neither is it in them to do good." (Jeremiah 10:2-5 ESV)
See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ. (Colossians 2:8 ESV)
Nice start, I'll provide color. Semiramis lived much later than Nimrod and was templated onto the extant lore; probably true of some of the other names too. The oldest name is Hawah (stolen from the real Eve), shortly templated onto Inanna (her grotesque caricature), who then picked up the other familiar Ishtar threads. Tammuz comes from Dumuzid of the Sumerian King List. The names in the attachment come from a wide and varied field and many do not syncretize them so it's best to stick to the clearest threads.
"The legend describes her descent from heaven within a giant egg, landing in the Euphrates River during sunrise on the first Sunday following the vernal equinox." That's not at all ancient, way too specific, but is a conflation of several later strands, including AD.
"The following Easter, the priests would sacrifice these now three-month-old babies and dye the eggs of Easter in their blood." Same imaginativeness. We do no credit to the enemy to admit him such farsightedness, Easter eggs are very ad hoc and do not have this hyperspecific root. Plus the legend of the dying husband reincarnated as the baby was usually not conflated with the legend of the baby sacrificed for the sins of others, as the latter defeats the purpose of the former.
There's one mention of Easter in KJV but it translates Pascha, the Passover season, which is mandated in Leviticus 23 with different rules (including having the Jews worship on what is now Resurrection Sunday, there called Firstfruits: Jews on Sunday, a real shocker). However, there are plenty of mentions of Ashtarte/Ashtoreth and Asherah/Asherim in the Hebrew, and they should be consulted for this narrative.
I've found ways to accommodate the followers of Jesus who also like "Easter", and the ways of peace are very beneficial here. However, for each person who is convicted against celebration of Easter, and who finds other ways to celebrate an annual Resurrection Day as God indicates, I uphold entirely the right of conscience as long as the facts are stuck to. There are some good bits in the above.
