Botticelli's Muse Died Not TB, But Tumor?

The enduring mystery surrounding the death of Simonetta Vespucci, the celebrated beauty of Renaissance Florence and muse to Sandro Botticelli, may finally be solved. For centuries, her passing at the age of 23 in 1476 was attributed to tuberculosis, a common ailment of the era.

A collaborative study by researchers from Queen Mary University of London, Università Campus Bio-Medico di Roma, and the University of California now suggests a different cause: a pituitary tumor. This theory builds upon earlier research proposing she suffered from a pituitary adenoma.

To support their hypothesis, the team employed facial recognition algorithms on five portraits of Vespucci. They meticulously tracked subtle shifts in her facial features over time, noting changes indicative of excess growth hormone and prolactin. These hormonal shifts can alter facial structure and, in rare cases, trigger lactation in non-pregnant individuals, a phenomenon potentially depicted in Botticelli's "Allegorical Portrait of a Woman."

Further evidence emerged from historical correspondence. Letters between her father-in-law, Piero Vespucci, and Lorenzo de' Medici, Florence's ruler, describe Simonetta collapsing at a ball. She subsequently experienced severe headaches, hallucinations, vomiting, and fever, forcing her to remain in a darkened room. Researchers interpret these symptoms as signs of a rapidly expanding pituitary tumor.

The study also considered a documented incident involving Alfonso II of Aragon, suggesting it might have aggravated the tumor, leading to bleeding or swelling. This event, known as pituitary tumor apoplexy, aligns with historical accounts of her rapid decline, offering a more plausible explanation than tuberculosis. While acknowledging the inherent uncertainties in diagnosing an illness centuries later, the researchers find the combined evidence compelling.
