The Robe of Ruin: How King Xerxes’ Forbidden Affair Triggered the Brutal Erasing of a Royal Bloodline
In 479 BC, deep within the labyrinthine corridors of the Persian royal palace, a woman of the highest nobility was subjected to a punishment so horrific that Herodotus, the father of history, nearly refused to record it. This woman was not a criminal or a spy; she was the wife of Masistes, the King’s own brother, and a member of the most protected bloodline in the Achaemenid Empire. Her mutilation was not the result of a war or a rebellion, but the final, bloody act in a drama of lust, betrayal, and weaponized tradition initiated by King Xerxes I.
To understand the savagery that unfolded in the palace, one must first look at the psychological state of Xerxes. Just a year prior, he had witnessed the annihilation of his fleet at the Battle of Salamis. He had crossed the Hellespont as a god-king intended to erase Greece from the map, only to retreat in shame, leaving his generals to be slaughtered at Plataea. For a monarch whose authority rested on the perception of divine favor and absolute invincibility, this external failure created an internal vacuum. Xerxes stopped looking for conquests abroad and began looking for them within his own court.
His first target was his sister-in-law, the wife of his brother Masistes. In a court where the King’s word was law, she did the unthinkable: she said no. Xerxes, perhaps still stung by his defeat in Greece, did not use force—not out of morality, but out of fear of Masistes, a powerful governor with a loyal army in Bactria. Instead, Xerxes played a long game. He arranged a marriage between his eldest son, Crown Prince Darius, and Masistes’ daughter, Artaynte. This political move was a Trojan horse designed to bring the woman he desired into his immediate household.
However, once Artaynte was within the palace walls, Xerxes’ obsession shifted from the mother to the daughter. He began a clandestine affair with his own daughter-in-law. The secret might have remained buried if not for Xerxes’ lack of discipline. In a moment of passion, he swore a sacred royal oath to Artaynte, promising her anything she desired. In the Persian system, a King could not break an oath without inviting cosmic disorder. Artaynte did not ask for gold or provinces; she asked for the robe Xerxes was wearing—a unique, handwoven garment made for him by his wife, Queen Amestris.
The robe was a confession. When Artaynte wore it, the affair became public knowledge. Queen Amestris did not react with a simple confrontation. As the daughter of one of the noble conspirators who had put the dynasty on the throne, she understood that her power depended on her status. To be publicly humiliated by a mistress was a threat to her survival. She waited for the King’s birthday, a day when custom dictated that the King must grant any request made during the royal feast.
Before the assembled nobility of the empire, Amestris made her move. She didn’t ask for the mistress’s head; she asked for the mistress’s mother—the woman who had originally refused the King. Xerxes was trapped by his own traditions. He tried to beg, he tried to offer Masistes other wives, even his own daughter, but the Queen was immovable. He was forced to hand over his sister-in-law to the Queen’s torturers.
The wife of Masistes was systematically mutilated. Her features—ears, nose, lips, and breasts—were severed, and she was sent back to her husband as a living message. The horror of the act drove Masistes into open revolt, but he and his sons were intercepted and executed by the King’s cavalry before they could reach their power base in Bactria. An entire branch of the royal family was erased to cover a scandal the King himself had authored.
The tragedy of Xerxes’ reign is that he proved the King was no longer a protector of the “truth” or the family, but a man easily manipulated by the very rituals that sustained his throne. This loss of respect was fatal. Fourteen years later, Xerxes was murdered in his bed by the commander of his own bodyguard and a court eunuch. The man who had whipped the sea and burned Athens died at the hands of those who realized that proximity to the King was no longer a place of safety, but a place of slaughter.
