The summer of 1959 should have been another season of triumph for Maria Callas. The voice that had conquered La Scala and the Metropolitan Opera was still hers, even if the critics had begun to whisper that the flame was burning lower. But when Aristotle Onasis invited her aboard his yacht, the Christina, for a three-week cruise through the Mediterranean, the greatest soprano of the century made a choice that would cost her everything: her marriage, her career, and eventually her sanity. She was thirty-five years old, and she believed she had finally found love.

The invitation arrived in the summer, extended to Maria and her husband, Giovanni Battista Meneghini. Maria initially declined, citing work commitments. But Onasis pressed, and she gave in. Meneghini refused to go.

He had no desire to set foot on the floating palace of a man whose fortune and reputation preceded him. So Maria sailed without him, into the company of celebrities—American, British, Greek—who filled the decks of the $3 million yacht. Winston Churchill was there with his wife. The sea was warm, the days luxurious, and the host was attentive.

Onasis courted her with a persistence that stunned everyone watching. Wherever Maria went, he appeared. He showered her with compliments and enormous bouquets of roses. Flowers arrived at her apartments, at restaurants where she dined, at her dressing room before performances.

They behaved as if they had forgotten they had families. All of it unfolded in front of Onasis’s official wife. Their first encounter had happened earlier, at a party organized in her honor. Onasis had approached her, kissed her hand, and spoken to her in Greek.

“Lady, you remind me of a Greek goddess,” he said. “That’s exactly how I imagined you. It is a great honor for me to meet you. I hope we will meet again.

”

From that moment, wherever Callas went, Onasis was there. And when the cruise ended, Maria Callas was a different woman. For the first time in her life, she said, she felt infinitely happy. She had fallen in love, and she believed she was loved in return.

Aristotle Onasis was not free when he pursued her. In 1946, he had married Athina Livanos, the daughter of his main competitor. She was seventeen on the day of the wedding. A year later came their son, Alexander, the heir Onasis had wanted.

Then Christina was born, a daughter he had not particularly desired—he already had his son and heir, and did not need another child. Business consumed him, and he spent little time with his family. He and Athina had an unspoken agreement: each would live their own life. But the affair with Callas was not a private arrangement.

It was public humiliation, played out in front of the most famous people in the world, and Athina could forgive her husband many things—but not that. Meneghini, for his part, was surprised. He loved his wife and was ready to forgive the vacation romance. Maria would not even hear of it.

For the first time, she truly loved and felt loved. She forgot her career entirely. Giovanni Battista Meneghini had been the architect of that career. A wealthy Italian entrepreneur and a great connoisseur of opera, he had become Maria’s empresario and, in 1949, her husband.

He was not tall, and he was considerably older than she was. Maria admitted in later years that she loved him like a daughter loves a father, while Meneghini always treated her as a beloved woman, fiercely guarding her from unwanted attention. Under his management, Callas had risen to the top of the opera world. Born in 1923 in New York to Greek immigrant parents, she had begun her musical education in childhood, but her path to success did not unfold in America.

It unfolded in Greece, where she arrived in 1937 with her mother and sister. Her big breakthrough came in 1947, when she portrayed Joan of Arc in Verona and left a profound impression on the audience. From there, she had performed on stages worldwide, gaining increasing recognition and fame through boundless diligence, talent, and perpetually unsatisfied ambitions. She became the prima donna of La Scala in Milan and the Metropolitan Opera in New York, carrying herself like a queen of opera.

She chose only the best partners, rejecting the weak or lesser-known. “I don’t want my name associated with tastelessness,” she would repeat. She had another weakness: she thirsted for compliments, even if they were not entirely truthful. She wanted to hear that she was the best, the most beautiful, the unique.

And beneath the queenly confidence lay a deeper fear—that she might once again fall into poverty. By the second half of the 1950s, her popularity had begun to wane. The singer continued to live, sleep, eat, move, and breathe only with thoughts of her arias. But that was before Onasis.

In the summer of 1959, after the cruise, Maria’s husband was left behind. Athina Onasis filed for divorce. The proceedings reportedly diminished Aristotle’s wealth somewhat, but for the enamored Callas, none of that mattered. She had completely forgotten her opera career—the significant success, the global recognition, the magnificent stage creations.

New contracts and offers from the best theaters and opera houses went unanswered. She believed in a man who loved to play, spend money, and enjoy everything life brought him. Maria and Aristotle awaited their divorces while traveling between Monaco and Athens. When journalists asked her about the romance, she did not hide.

“Yes, I fell in love like an eighteen-year-old, and I’m not ashamed to admit it,” she said. “There are rumors in the world that I loved Onasis for his billions. What nonsense. I earn enough money to buy myself a yacht like Christina.

Why did I love him? Because he is the first man who treats me like a woman, not like a money-making machine. ”

She had high hopes for marriage. Onasis did not.

He continued to shower her with precious gifts, but the passionate love was fading month by month. Maria told herself everything would be fine, that a lavish wedding was coming. Instead, the ardent lover slowly turned into something else. More and more often, she found herself alone in the vast, empty mansions of her beloved billionaire while he spent time with his children, trying to regain their love and involvement in their upbringing.

He also began seeing other women, and it did not escape her attention. She waited for weeks. He did not call. He did not respond to her calls.

Then, after long silences, another bouquet would arrive with a lovely necklace, assurances of adoration, and he would come for a few days. Maria’s anger quickly turned to joy. Each reunion was a new honeymoon. As proof of his feelings, Onasis once promised to buy a castle in France where they would both live.

Maria was thrilled. But the castle was purchased by someone else, and the billionaire did not even remember his promise. The people around her marveled at her blindness, at the almost fanatical love of the singer. It seemed that only Maria did not see the coldness and indifference of the billionaire.

Her cherished dream was to have a child. When pregnancy finally occurred, Onasis acted cruelly and heartlessly. He did not like the news, and he quickly left. Maria was unable to terminate the pregnancy.

Their only son, Homer, was born prematurely and died two hours later. Maria buried him alone in a cemetery in Milan. She visited her son’s grave for the rest of her life. The stress nearly cost her the voice that had made her famous.

In 1965, in Paris, she could not finish singing her aria. Little remained of her former virtuosity. Since then, Callas no longer performed on stage, only giving solo concerts. Her career had come to an end.

After losing her child, she faced growing dilemmas. She could not live with Onasis anymore, yet she could not imagine life without him. At forty-three, she had no home, no family, no husband, no children of her own. Onasis bought her an apartment in Paris to lift her spirits.

In 1968, Maria learned that Aristotle was planning to marry Jacqueline Kennedy, the widow of the American president. It was in his style, she realized; he always said he wanted it all—women, money, happiness. Why not marry the most famous widow in the world? It is hard to describe the blow it was for her.

For eight years she had been waiting for a divorce from her husband, and when she finally got her official freedom, the man of her life married another woman. At first he claimed it was untrue, that he only loved her, that his affair with Jacqueline was just for publicity. The billionaire was lying. In fact, he was already married to Jacqueline Kennedy.

Maria had a nervous breakdown. She stopped leaving her home and began taking sedatives. In the depths of her heart, she still hoped that Aristotle would leave Jacqueline, whose spending irritated him. But nothing of the kind happened.

In Greece, they openly say that Onasis’s fortune is cursed—that these riches have brought no one happiness, only misfortune. Even looked at completely objectively, it is hard not to be frightened. A few years after marrying Jacqueline, Aristotle’s beloved son Alexander died in an aviation accident at the age of only twenty-five. The main heir to his father’s business was gone.

Aristotle himself switched off the life support for his son. Interestingly, it was Jacqueline who had suggested that Alexander take over the controls of his father’s plane that day. A year and a half later, Onasis’s first wife, Athina, died from an overdose. Feeling unwell, Onasis collapsed after his son’s death.

He died at the age of sixty-nine. All the assets were inherited by his daughter, Christina. She would not be around much longer either. In March 1975, Onasis’s health deteriorated significantly.

Maria could not stay with him because his official wife was there. But when Jackie was not around, Artemis, Onasis’s sister, informed Maria that she could come. That became their farewell. Aristotle remained unconscious for five weeks.

Watching the love of her life connected to various devices, the Greek woman whispered that she would never leave him, that she would love him endlessly. Aristotle Onasis was buried next to his son’s grave on the small island of Skorpios. One of the most luxurious yachts of its time, once owned by Onasis, was left to rust because there was no one left to maintain it. Maria continued to suffer, immersed in agony from grief for her beloved and from loneliness.

In her final years, the opera diva sought solace in forbidden substances. On September 16, 1977, at the age of fifty-three, she was found in her own bed. Officially, the cause of death was reported as a heart attack. Per her last will, the ashes of the singer were scattered around the Ionian island of Skorpios, where Aristotle was buried.

In the end, she kept her promise to her beloved. She never left him.
