When Atreus got married, he was furious when he found that his wife and his brother, Thyestes, shared the same bed. Then an Oracle came and said that one of the brothers would become the king of Mycenae. As you can imagine, the two brothers quarreled. Atreus was still worried about his wife's infidelity, so he drove themis out of the city and took charge of the kingdom himself. However, power did not alleviate Atreus's anger towards his brother. He punished the thief again, pretended to hope to reach a settlement, and invited his brothers to a friendly reunion banquet. The main course is exactly the same as his grandfather Tantalus's recipe. Atreus killed several sons of Thiestes, stewed them and gave them to his unsuspecting father. The thief knew what he was eating, so he cursed Atreus and his descendants. This is the third curse on Tantalus's descendants.
After that, Tejestes received instructions from Apollo, asking him to take revenge on the enemy who killed the child. Tyus, now only one daughter, named peropia. He raped her in the dark and then hid. Peropia doesn't know who the attacker is. She's still pregnant. Only one sword is still there, which was left by the man who didn't know his true identity. Peropia later married Atreus because Atreus divorced his unfaithful wife. Atreus was very happy, because Peropia soon gave birth to a son named Egostos. He foolishly thought that this son was his own, so he would not be affected by family blood feud. However, the curse of the gods will not end with people's good wishes. A drought hit the whole country, and the Oracle came, saying that the disaster would only end if the thief was brought back.
Atreus finally found the thief and locked him up. He ordered Peropia's youngest son, Egostos, who he thought was his own son, to complete his first manly task, that is, to raise his mother's sword and kill the prisoner (he is the real father of this young man). The boy raised his sword and went into Tethys' cell. Thyestes recognized his sword at once. He sent for his daughter, Peropia. When Peropia learned the truth, she raised her sword and cut herself. The young Egyptian finally discovered his real life experience and decided to take revenge on Atreus. He picked up the bloody sword and went back to Atreus, where he killed him. The thief replaced his brother and became the king of Mycenae.
During this period, Agamemnon, Atreus's son, was saved by his servants from being slaughtered and grew up in exile. As an adult, he married Clytaemestra, the daughter of the king of Sparta, and the queen of Sparta came to help Agamemnon regain Mycenae's throne. Thyestes and his son were expelled, and Thyestes died soon.
Clytaemestra gave birth to a son and three daughters for Agamemnon. Agamemnon was one of the warlords in Greece and took part in the Trojan War. Clytaemestra's lover was none other than Aegisthus, the son of Thyestes. After Agamemnon entered the war, Egyptos had entered the palace in disguise and seduced his wife, Queen Clytaemestra. They conspired to kill Agamemnon together, and finally when Agamemnon returned from the Trojan War, he was chopped to pieces in the bathroom.
Orestes, Agamemnon's son, was sent away when Clytaemestra and her lover plotted to kill Agamemnon. Now, Apollo came to tell the truth about his father's death and demanded his revenge. Orestes protested strongly, saying that his parents' quarrel had nothing to do with him, and he didn't want to take part in any form of killing. However, Apollo made it clear that whether he liked it or not, Orestes was Agamemnon's son, so he had the responsibility to avenge his father. If Orestes does not obey, the gods will try their best to make his life not smooth. Orestes knew that if he killed his mother, Nemesis would take crazy revenge on him, because Nemesis was the goddess of the underworld, and she protected her rights as a mother. No matter what he does, there will be no good result. Finally, Orestes reluctantly decided that he should stand on his father's side, because he is also a man. In this way, he killed his mother and her lover
Nemesis really came to get back at Orestes and make him insane. After a year of mental torture and blow, he went to Athens and sought protection in the temple of Athena. The goddess Athena, together with the first jury composed of human beings, ruled that Orestes was innocent and rescued his family from the curse. Finally, he got married, inherited the throne of Sparta, and started a new bloodline, without the blood feud of the past.
The story of Orestes and Atreus House tells us that the curse of the family can be lifted through humility, piety, enduring pain for no reason and faith in God and life.
