Did You Know? 12 Weird Legends About Synesthesia

⏱️ 6 min read

Synesthesia, a neurological phenomenon where stimulation of one sense triggers involuntary experiences in another, has captivated human imagination for centuries. While modern science has made significant strides in understanding this condition, numerous myths, legends, and bizarre tales have emerged throughout history. These strange stories blend fact with fiction, creating a fascinating tapestry of cultural beliefs about people who quite literally experience the world differently.

Ancient and Modern Myths Surrounding Synesthesia

1. The Medieval Witchcraft Connection

During the Middle Ages, individuals who claimed to see sounds or taste colors were sometimes accused of witchcraft or demonic possession. Legend has it that several women in 15th-century France were brought before ecclesiastical courts for describing religious hymns as having specific colors. These accounts suggest that synesthetes may have been persecuted for their neurological differences, though historical records remain fragmentary and difficult to verify. Some folklore scholars believe these tales were exaggerated or entirely fabricated during the witch-hunting hysteria, but they persist in local legends across Europe.

2. Pythagoras and the Music of Colored Spheres

Ancient Greek legends attribute synesthetic experiences to the philosopher Pythagoras, claiming he could see the colors of musical notes and planetary movements. According to these tales, he taught his followers that each celestial body produced a specific tone with its own corresponding hue, creating a cosmic symphony visible only to those with special perception. While there’s no concrete historical evidence that Pythagoras actually experienced synesthesia, this myth has endured for over two millennia and influenced countless mystical traditions.

3. The Russian Composer Who Tasted Symphonies

A peculiar legend surrounds the claim that composer Alexander Scriabin could taste entire orchestral arrangements. Stories passed down through musical circles suggest he would refuse to perform certain compositions because they had an unpleasant flavor. While Scriabin did genuinely experience color-sound synesthesia and created his “color organ,” the tales about tasting music appear to be embellishments added by romanticizing biographers and eager students seeking to mythologize their teacher’s already remarkable abilities.

4. The Artist Who Painted Sounds from the Dead

Victorian spiritualism gave rise to legends about artists who claimed to paint the colors they heard emanating from spirits during séances. One particularly persistent story involves a London painter who allegedly created portraits based entirely on the sonic signatures of deceased individuals. These tales merged the era’s fascination with both synesthesia and the supernatural, though no verifiable evidence supports the existence of such paranormal synesthetic abilities.

5. Indigenous Shamanic Color-Hearing Rituals

Various legends describe indigenous shamans across different cultures who purportedly developed synesthesia through specific ritual practices. These stories claim that certain ceremonial dances, chants, or plant medicines could temporarily or permanently grant practitioners the ability to see sound. While some entheogens can indeed create temporary cross-sensory experiences, the legends often exaggerate these effects and attribute mystical powers to naturally occurring neurological variations that likely existed independently of any rituals.

6. The Mathematical Savant Who Felt Numbers

A recurring legend in mathematical circles tells of a 19th-century calculating prodigy who claimed each number had a distinct texture and emotional quality. Stories suggest this individual could solve complex equations by “feeling” the smoothness or roughness of numerical relationships. While some synesthetes do experience number-form or ordinal linguistic personification, these tales have been embellished to the point where separating fact from fiction becomes nearly impossible.

7. The Poisoning Theory of Acquired Synesthesia

Dark legends from the Renaissance period suggest that certain noble families used specialized poisons to induce synesthesia in their children, believing it would grant them superior artistic or musical abilities. These myths claim that controlled exposure to mercury or lead compounds could “open the mind’s eye.” This dangerous folklore has no scientific basis and likely arose from observations of individuals who developed neurological symptoms—possibly including synesthetic experiences—from accidental heavy metal poisoning.

8. The Blind Prophet Who Saw Colors in Voices

Multiple cultures share variations of legends about blind prophets or oracles who could identify people by the colors they “saw” when hearing voices. These stories typically describe individuals who used this alleged ability to detect lies or predict future events. While some blind individuals do report synesthetic experiences, the prophetic elements of these legends clearly belong to the realm of mythology rather than documented neurological phenomena.

9. The Literary Curse of Lord Byron’s Circle

A peculiar literary legend suggests that several members of Lord Byron’s social circle developed synesthesia after participating in the famous ghost story competition that produced Mary Shelley’s “Frankenstein.” According to this myth, the intense creative atmosphere and possibly opium use during that fateful summer somehow “infected” participants with crossed sensory perceptions. No historical evidence supports this romantic tale, though it continues to circulate in literary folklore.

10. The Ancient Egyptian Color Hieroglyphs Theory

Some fringe theories, bordering on legend, propose that ancient Egyptian hieroglyphs were designed by synesthetes who encoded the colors they associated with specific sounds into the writing system. Proponents claim this explains certain color choices in temple paintings and tomb decorations. Mainstream Egyptologists dismiss these ideas as unfounded speculation, but the legends persist in alternative archaeology circles.

11. The Mirror-Touch Epidemic of 1518

An unusual legend connects the famous Dancing Plague of 1518 in Strasbourg to mass mirror-touch synesthesia, where witnesses allegedly began physically feeling the dancers’ movements in their own bodies. This myth suggests the phenomenon spread like a contagion, causing hundreds to join the dance involuntarily. While the dancing plague was a real historical event, the synesthetic explanation is a modern invention with no period documentation to support it.

12. The Telepathic Twins with Shared Synesthesia

Perhaps the most persistent modern legend involves identical twins who allegedly share identical synesthetic experiences and can communicate through colored thoughts. Various versions of this story circulate online, sometimes claiming the twins were studied by secret government programs or prestigious universities. Despite thorough investigation by skeptics and researchers, no verifiable cases matching these extraordinary claims have been documented, though the legend continues to evolve with each retelling.

Separating Myth from Reality

These twelve legends demonstrate how synesthesia has captured human imagination across centuries and cultures. While synesthesia itself is a real and well-documented neurological condition affecting approximately 4% of the population, the myths surrounding it reveal more about human fascination with unusual perception than about the condition itself. Modern neuroscience continues to unravel the genuine mysteries of synesthesia, providing explanations far more interesting than the legends—even if less supernatural. Understanding these myths helps us appreciate both the remarkable nature of true synesthetic experiences and humanity’s eternal tendency to embellish the extraordinary into the mythological.
