Who is she, really? And could she even be… a man?

In this article, we’ll dive deep into the history and theories surrounding the painting, explore the psychology of its subject, examine medical diagnoses proposed by experts, and unpack the gender debate that has enthralled art historians for decades.

Whether you’re a casual art lover, a student, or simply curious about the hidden stories behind the world’s most famous painting, this guide will help you understand the allure of the Mona Lisa , and why she continues to capture the imagination of millions.

A Quick Overview: The Mona Lisa in Context

Before exploring the fascinating theories, it’s important to understand the basics of the painting.

  • Artist: Leonardo da Vinci (1452–1519)

  • Medium: Oil on poplar panel

  • Date: Believed to have been painted between 1503–1506, with possible later additions by Leonardo until around 1517

  • Current Location: Louvre Museum, Paris, France

  • Dimensions: 77 cm × 53 cm (30 in × 21 in)

Most scholars agree that the Mona Lisa is a portrait of Lisa Gherardini del Giocondo, the wife of a wealthy Florentine silk merchant. Commissioned by her husband, the painting became one of Leonardo’s greatest works. However, Leonardo never delivered the portrait to the family; instead, he kept it with him until his death in France.

That decision alone hints that the painting was more than just a commissioned work, it was something deeply personal for the artist. And that is where the mystery begins.

The Theory That Mona Lisa Was a Man

One of the most intriguing claims in art history is that the Mona Lisa is not a woman at all but rather a man, or at least inspired by one.

1. The Salai Hypothesis

Leonardo da Vinci had a male apprentice and companion named Gian Giacomo Caprotti, also known as Salai. Many art historians believe Salai may have been Leonardo’s muse. His features, particularly his delicate face, flowing hair, and gentle expression, appear in several of Leonardo’s other works.

Supporters of the theory argue:

  • Facial Structure: Comparisons between portraits of Salai and the Mona Lisa reveal striking similarities in the jawline, nose, and mouth.

  • Androgyny in Art: Leonardo often blended masculine and feminine traits in his figures, suggesting a fascination with androgyny.

  • Personal Connection: If Salai was indeed Leonardo’s lover or at least his muse, it makes sense that Leonardo might immortalize him in his greatest painting.

2. Symbolic Duality

Another interpretation suggests the Mona Lisa represents an idealized fusion of masculine and feminine qualities, perhaps a reflection of Leonardo’s belief in universal harmony. By merging genders into one enigmatic figure, Leonardo may have intended the Mona Lisa to symbolize balance, completeness, and human unity.

3. The Self-Portrait Theory

Some even suggest the Mona Lisa is a disguised self-portrait of Leonardo da Vinci. Modern digital overlays of Leonardo’s known self-portrait with the Mona Lisa show similar facial proportions. If true, this could mean Leonardo painted himself in feminine form, blurring gender boundaries intentionally.

Is the Mona Lisa Pregnant?

Another popular theory is that the Mona Lisa depicts a pregnant woman.

Evidence for Pregnancy:

  • Clothing Clues: Scholars point to the presence of a fine veil across her shoulders, which was commonly worn by women during pregnancy or after childbirth in Renaissance Italy.

  • Posture and Hands: Her slightly swollen hands and resting posture could suggest the serenity of an expectant mother.

  • Commission Context: The portrait was likely commissioned by Francesco del Giocondo to celebrate his wife Lisa’s pregnancy or the birth of their child.

Counterarguments:

  • Some argue the veil may simply be a fashionable accessory of the time.

  • There’s no definitive historical documentation proving Lisa Gherardini was pregnant during the commission.

Still, the “pregnancy theory” adds another layer of intimacy to the Mona Lisa’s story, portraying her as not just a sitter but a woman at a pivotal life stage.

The Psychology of the Mona Lisa

What is it about this painting that makes us feel so unsettled, captivated, and intrigued at the same time? Psychologists, neuroscientists, and art theorists have studied the Mona Lisa extensively to decode its psychological impact.

1. The Power of the Smile

The Mona Lisa’s smile is arguably the most analyzed expression in history. It appears to shift depending on where you focus your gaze:

  • Looking directly at her mouth: The smile seems subtle, almost nonexistent.

  • Looking at her eyes or other parts of the painting: The smile appears broader and warmer.

This illusion is caused by Leonardo’s mastery of sfumato, a technique of soft, gradual transitions in shading. It tricks the human visual system, creating an ever-changing smile.

2. The Gaze Effect

The Mona Lisa’s eyes appear to follow the viewer around the room. This is not magic but the result of Leonardo’s precise use of perspective and shadowing. Psychologically, this gives the painting a sense of intimacy and connection, as though she’s engaging personally with each viewer.

3. Emotional Ambiguity

Is she happy, sad, amused, or contemplative? The Mona Lisa’s expression defies easy categorization. Psychologists call this emotional ambiguity, and it activates our brains by forcing us to constantly reinterpret her mood. That’s one reason why viewers never tire of looking at her.

The Mona Lisa’s Diagnosis: Medical Theories

Interestingly, physicians and researchers have examined the Mona Lisa as though she were a real patient. Several medical diagnoses have been proposed based on visual analysis of her features.

1. High Cholesterol or Lipoma

Some doctors suggest the slight swelling in the Mona Lisa’s neck and the yellowish tone of her skin could indicate high cholesterol or a fatty tissue buildup (lipoma).

2. Hypothyroidism

Others claim her thin hairline, slightly swollen hands, and lack of eyebrows suggest hypothyroidism, a condition caused by an underactive thyroid.

3. Bell’s Palsy

A 2010 study proposed she might have had Bell’s palsy, a temporary facial paralysis, which could explain the asymmetry of her smile.

4. No Illness at All

Of course, skeptics argue these medical theories are speculative at best. After all, the Mona Lisa is a painted image, not a medical record. Leonardo could have idealized, stylized, or intentionally modified features for artistic reasons.

Does the Mona Lisa Have a Gender?

This question may seem simple, but in the world of art history, it is surprisingly complex.

1. Traditional View

Traditionally, the Mona Lisa is recognized as a portrait of Lisa Gherardini, a Florentine woman. From this perspective, she is unequivocally female.

2. The Androgynous Argument

However, the blending of masculine and feminine traits in the painting makes some wonder if Leonardo intentionally created an androgynous figure. The subtle masculinity in her jawline, nose, and hands challenges the rigid gender categories of the Renaissance.

3. Symbolic Gender Fluidity

In Renaissance philosophy, the merging of opposites (male and female, light and dark, body and spirit) represented perfection and unity. Thus, the Mona Lisa may transcend gender altogether, embodying a universal human essence rather than a specific identity.

Why the Theories Matter

Why do scholars and enthusiasts continue to debate the Mona Lisa’s gender, psychology, and medical condition?

  1. Enduring Mystery: The ambiguity keeps the painting alive in our cultural imagination.

  2. Leonardo’s Genius: Each theory reveals new layers of Leonardo’s brilliance, not just as an artist but as a thinker, scientist, and philosopher.

  3. Cultural Reflection: Our interpretations of the Mona Lisa often reflect the values and concerns of our time, from gender fluidity to medical science.

Mona Lisa and Modern Popularity

The Mona Lisa is not just an art piece, it’s a global icon. Reproduced on posters, merchandise, and countless memes, her image generates millions for tourism and retail industries.

For travelers, the Louvre Museum remains a bucket-list destination, with the Mona Lisa as its crown jewel. Standing in front of her is an almost ritualistic experience, even if the glass case and crowds make intimacy difficult.

For affiliate marketers, the Mona Lisa provides countless tie-in opportunities, from art books and museum guides to prints, digital courses, and travel packages to Paris. The painting’s enduring appeal ensures that products and content connected to it remain evergreen.

Final Thoughts

The Mona Lisa is more than just a portrait; it’s a puzzle, a mirror, and a cultural touchstone. Whether she is a man, a woman, pregnant, healthy, or ill, what truly matters is her power to provoke curiosity and conversation.

  • If she’s Salai in disguise, then she tells a story of Leonardo’s personal life and artistic daring.

  • If she’s a pregnant Lisa Gherardini, then she reflects the intimate joys of family and motherhood.

  • If she embodies both male and female traits, then she becomes a timeless symbol of human wholeness.

And perhaps that is the greatest mystery of all: the Mona Lisa is not one person, one theory, or one truth. She is many things at once, a masterpiece that continues to challenge how we see art, identity, and ourselves.
