Curiosities

Illusive Pietà

Gianni Sarcone

Uncovering the subtle visual tricks Michelangelo wove into his masterpiece.

We’re not very good at judging the true size and positioning of objects just by looking. Take Michelangelo’s Pietà—it hides some subtle, conceptual “illusions”:

  • If they were standing, the Virgin Mary would actually be much taller than Christ, which may be surprising.
  • Her knees are slightly off-center, forming a kind of base or pedestal that supports Christ’s body.
  • And while logically the Virgin should look older, her face is almost childlike, creating a striking contrast with the mature, somber face of her son.

Michelangelo himself explained this choice:
“The mother had to be young—young enough to appear forever a virgin. Meanwhile, her son, who took on our human nature, must, in the stripping away of death, be a man like any other.”

Art is full of illusions designed to meet the visual expectations of viewers—and sometimes to correct what might seem off or unnatural to the eye. Because reality, at times, doesn’t always feel quite real or right to those who look at it.

And one last curious detail: Pietà is the only work Michelangelo ever signed. Stung by whispers that another sculptor had made it, he returned one night and boldly carved his name across Mary’s sash— “MICHAELA[N]GELVS BONAROTVS FLORENT[INVS] FACIEBAT” (Michelangelo Buonarroti, the Florentine, made this). A rare flash of pride from an artist who usually let his work speak for itself.)

The First Hero’s Quest for Immortality

Gianni Sarcone

The Epic of Gilgamesh is the oldest known long-form poem in history—predating the Bible, The Iliad, and even the Mahābhārata. Often hailed as the first great work of world literature, this ancient Babylonian epic tells the story of a mighty hero, king of Uruk, who embarks on a quest for immortality. Its timeless themes—love, friendship, grief, the fear of death—still speak to us with surprising clarity.

Originally transmitted orally, the poem was later inscribed in cuneiform on clay tablets. The version we know today was written in Akkadian, the lingua franca of the Babylonian Empire, over four thousand years ago. For centuries, the text was lost to history—until its rediscovery in fragmented form during the nineteenth century sparked renewed interest.

The tale begins with Gilgamesh, a powerful yet restless king, and Enkidu, a wild man created by the gods to challenge him. After a dramatic contest of strength, the two become inseparable companions. They journey to the sacred Cedar Forest, where they slay its divine guardian, Humbaba. When Gilgamesh rejects the goddess Ishtar, she unleashes the Bull of Heaven. The two heroes kill the beast—an act that angers the gods, who punish them by taking Enkidu’s life.

Stricken by grief, Gilgamesh sets out on a perilous journey in search of eternal life. He ultimately meets Utnapishtim, a flood survivor granted immortality by the gods. From him, Gilgamesh learns a harsh truth: death is man’s destiny; immortality belongs only to the divine.

More than a heroic saga, The Epic of Gilgamesh established the prototype for later epic heroes—from Heracles to Odysseus—and continues to inspire writers and artists today. Its enduring influence stretches across millennia and cultures.

In Forests, Robert Pogue Harrison draws on The Epic of Gilgamesh to explore the symbolic power of forests in the Western imagination. Gilgamesh’s felling of the sacred cedars and slaying of Humbaba reflects humanity’s first mythic confrontation with nature—marking the forest not as sanctuary, but as territory to be mastered. For Harrison, this moment signals the dawn of civilization’s long, uneasy relationship with the wild.

To truly grasp the spirit of the ancient world, I encourage you to read The Aeneid by Virgil, Homer’s Iliad and Odyssey, as well as the timeless Mahābhārata and The Epic of Gilgamesh. These foundational texts continue to illuminate the hopes, fears, and questions that have shaped human thought across the ages.

A Hidden Time Machine

Gianni Sarcone

We all carry within us a time machine—hidden in plain sight, right in the middle of our face. It may sound unlikely, but the NOSE is the only sensory organ capable of transporting us into the past without our even realizing it.

Our sense of smell activates memories like no other. A single scent can unlock a precise moment from childhood or early adulthood: the fragrance of oranges at Christmastime, melting snow during your first school field trip in winter, the scent of your sweetheart’s sweater the day you met, your grandmother’s simmering tomato sauce during Sunday lunches, the waxed floor of your grandparents’ house, school glue in primary class, the sunscreen of beachside summers, old book ink in the town library, the leather of your first satchel, or the aroma of fresh coffee at dawn when everyone else was still asleep…

The nose is a powerful trigger for nostalgia because the olfactory bulb, where smells are processed, is directly connected to the limbic system—the brain’s emotional and memory center. This close link allows smells to summon vivid memories, often with startling clarity, and sometimes, with them, an unexpected flood of emotions.

Each smell opens a door to a suspended instant—fragile, vivid. It’s an inward journey to a hidden past, a place buried deep, that suddenly bursts forth like a firework of nostalgia.

Each of us holds a palette of scents capable of bringing us back—suddenly, vividly—to a time that’s gone. Mine carries rustic, earthy tones: my maternal grandparents were farmers, and I spent much of my early childhood with them in the mountains of Irpinia.

I remember the sticky perfume of freshly harvested tobacco leaves, the white film of yeast clinging to wine grapes, the wild asparagus gathered by riverbanks, the unmistakable sweet scent of the ceuze—what we called mulberries in dialect—and the zenzifero, a local mint that gave ricotta ravioli its delicate fragrance…

I doubt I’ll ever stumble across those long-lost smells again—or perhaps they’re just dormant, waiting. But if they do return, that would be the most beautiful time travel I could ever hope for.

And you? What scents carry you away to other times, other worlds?

Smelling the Color 9: When Numbers Take Shape and Color

Gianni Sarcone

In English, the expression to smell the color 9 describes something completely impossible…

And yet, some people have the unusual ability to mentally visualize colors or spatial patterns when thinking about units of time—or more broadly, numbers. This phenomenon, known as synesthesia (from the Greek syn, “together”, and aisthēsis, “sensation”), occurs when stimulation of one sense involuntarily triggers sensations in another. It’s not a figure of speech—these perceptions feel very real to those who experience them.

The first documented case in medical literature appeared in 1710. Dr. John Thomas Woolhouse (1650–1734), an ophthalmologist to King James II of England, reported a blind young man who claimed he could perceive colors induced by sounds.

Neuroscientist Vilayanur S. Ramachandran and his team at the University of California, San Diego, observed that the most common form of synesthesia links “graphemes“—letters or numbers—to specific colors. Since my work bridges art and mathematics, I’ll focus here on number-based synesthesia.

People who experience synesthesia in its pure form are relatively few. However, many report strikingly similar associations between numbers and colors or spatial layouts, suggesting these perceptions aren’t just products of imagination or attention-seeking. For example, number–form synesthesia may result from cross-activation between brain regions in the parietal lobe that handle numerical and spatial processing. In contrast, number–color synesthesia likely stems from an overabundance of connections between adjacent areas that interfere with each other when triggered (see fig. 1 below).

brain synesthesia

Figures 2 and 3 illustrate common synesthetic patterns—either as color associations (fig. 2) or spatial arrangements (fig. 3, based on observations by Sir Francis Galton). Statistically, people often associate the digits 0 or 1—and sometimes 8 or 9—with black or white. Yellow, red, and blue are typically linked to smaller digits like 2, 3, or 4, while brown, purple, and gray tend to be tied to larger ones like 6, 7, or 8. Curiously, it’s not the idea of the number but the visual form of the digit that seems to trigger the sensation. For instance, when the number 5 is shown as the Roman numeral V, many synesthetes report no color at all.

The Word: From Incantation to Influence

Gianni Sarcone

In the beginning, whether real or invented, certain words—many from a distant past—formed a bridge between humans and the great Mystery. One such word that survived the ages, still cloaked in a strange aura of power, is Abracadabra. Even today, magicians use it to conjure effect, echoing its ancient weight.

Originally, Abracadabra wasn’t just theatrical. It was an apotropaic charm—spoken or inscribed to ward off harm. The earliest record, from the 2nd century CE in a medical treatise by Serenus Sammonicus, describes it as a remedy for fever. Written in a tapering triangle, the word visually dissolved with each line, symbolizing the illness retreating. Its origins are uncertain. Some link it to Aramaic or Hebrew—“I create as I speak” (אברא כדברא). Others see it as a coded sequence from the Greek alphabet (ΑΒΓΔ), or a variant of another potent name: Abraxas.

An incantation born of another—what a journey through a world woven in magic.

Abraxas (Greek: ἀβραξάς), central to the Gnostic teachings of Basilides, named a powerful being ruling over 365 heavens. Engraved on amulets, Abraxas was thought to hold innate power. These stones, often cited in magical texts, show a belief system where sound and symbol merged—where the right word could invoke protection, healing, or cosmic order. Its earlier spelling, Abrasax, likely morphed through transliteration. With seven letters, the name was also tied to the seven classical planets, deepening its cosmic charge. Whatever its true roots, one idea persists: properly arranged, words carry force.

Across time, this belief shifted but never vanished. Ancient incantations gave way to new forms of verbal power.

Antiphon of Athens (5th century BCE) stripped speech of ritual but kept its essence. Considered a forerunner of psychotherapy, he used dialogue to ease emotional suffering. His method wasn’t mystical—it was precise, rooted in rhetoric and clarity. Where once words summoned the divine, now they served insight and balance.

Language, even without the trappings of magic, remains transformative. In the 20th century, thinkers like Paul Watzlawick showed how communication doesn’t just reflect our world—it shapes it. A change in phrasing can shift perception. A word can open or close a mind.

From Abraxas to Abracadabra, from spell to speech, the thread continues: words influence, connect, heal. What began as incantation lives on as conversation—still crafting reality, still carrying power.

The Interrogation Mark: From Greek Semicolons to Spanish Twists

Gianni Sarcone

In ancient Greek, questions were marked by a semicolon (Ερωτηματικό) rather than a question mark. This practice faded over time, and no special punctuation indicated questions in antiquity. The modern question mark emerged in the Middle Ages when scribes used “qo” (from Latin quaestio). To avoid confusion, they stacked the letters, turning the Q into a curl and the O into a dot, creating the question mark (“?”). In Spanish, the question mark was placed only at the end until 1754, when the Ortografía de la Real Academia introduced the inverted opening question mark (¿), as in: ¿Qué edad tienes? (How old are you?).

The Silent Orbit of Thought

Gianni Sarcone

The circle, a timeless symbol of wholeness, is found at the core of human thought. In the West, it evokes the Pythagorean harmony of the cosmos, the eternal return of Nietzsche, the indivisible unity of Being. A form without beginning or end, it embodies the perfect balance between presence and absence, the finite and the infinite.
In Eastern traditions, the ensō (円相)—literally “circular form”—is a distilled gesture of perception, a visual echo of clarity. Not merely a shape, but an experience, it is drawn in a single stroke, capturing the ephemeral moment where thought and movement dissolve into pure expression. It is said that the earliest Zen painting was an ensō, traced to offer a student something tangible yet elusive, a paradox to ponder.
A circle can be brushed on paper, traced in sand, drawn on a misted window, or merely imagined. It lacks nothing, needs nothing, yet contains all things. In its quiet completeness, it is not an answer, but an opening—an invitation to see beyond the limits of form.

Umbrella Illusion

Gianni Sarcone

One of my illusions from the late ’90s. Take a look at the colorful umbrellas in Figures A and B of the table below—are they the same or different? About 80% of people will say that Umbrella A has jagged, zigzag edges, while Umbrella B has a smooth, wavy outline. But here’s the trick—you’ve been fooled by the brightness contrast of the rays inside the umbrellas. In reality, both umbrellas are identical in shape, perfectly congruent.

This illusion works even when only the lines of the shapes are emphasized. As demonstrated in the table below, the outline of Umbrella A appears jagged and zigzagged, while Umbrella B seems to have, once again, a smooth, wavy outline.

This illusion shows a phenomenon called curvature blindness, which was rediscovered in 2017 by Japanese psychologist Kohske Takahashi. He created a powerful variant and studied its impact on how we perceive shapes.

The Soul of Books: A Journey from Bark to Pages

Gianni Sarcone

I must have been born in a library, for the love I hold for books is immeasurable. A book awakens all the senses in me: the visual pleasure, the tactile warmth, the scent of cinnamon or vanilla from old pages, the soft rustle of turning leaves, and even the taste… To me, no digital book will ever replace the presence of a real one, with its soul and essence.

But the journey from tablet to scroll, to codex, and finally to the modern book spans millennia. The codex, the direct ancestor of today’s book, introduced a revolutionary format—pages bound along one edge—laying the foundation for how we read and store knowledge today.

Books, as we recognize them, became widespread during the Middle Ages, largely due to Gutenberg’s invention of the printing press. However, the codex itself dates back much further. It was made of sheets folded multiple times, often twice, to form a bifolio. These bifolia were sewn together into gatherings, allowing for binding and, when needed, rebinding. The most common structure consisted of four bifolia—eight sheets, totaling sixteen pages—known in Latin as quaternio. This term later gave rise to quaderno in Italian, cahier in French, and quire in English. Interestingly, the Latin word codex originally meant a block of wood, a nod to the materials once used for writing.

Even the word book has deep roots—its Old English form, bōc, likely stems from the Germanic root bōk-, meaning beech. This isn’t just a linguistic coincidence; early writings may have been carved into beech wood. In Slavic languages, the word for “letter,” буква (bukva), shares this origin. In Russian, Serbian, and Macedonian, букварь (bukvar’) or буквар (bukvar) refers to a child’s first reading textbook.

Similarly, the Latin word liber, which gave rise to libro in Italian and livre in French, originally meant “bark,” reinforcing the deep connection between books and trees. The Greek root biblio, is believed to be derived from βύβλος (búblos), meaning “papyrus,” named after the ancient Phoenician city of Byblos, a major hub of the papyrus trade.

From carved wood and tree bark to bound pages and printed volumes, books have always been deeply rooted in nature—both in language and in form.

Sphere of Influence of Our Ego

Gianni Sarcone

Imperialism is not limited to a group or a country. In fact, each of us is, in essence, an imperialist, striving—whether subtly or forcefully, skillfully or clumsily—to expand his / her sphere of influence in the world. The methods we employ vary from person to person: some are conciliators, while others are more combative.
When I was 25, I empirically explored how these spheres of influence, which I termed ECFs, interacted between two individuals. To make the concept understandable, I employed the metaphor of colors. This brief is discussed in my book, “Le Voile d’Iris” (French edition, see image below). Perhaps one day, I will revisit this study to develop it into something more rigorous.
