Palmistry, the Science of the Hand

The Fortune Teller, painted by Caravaggio at the end of the 16th century, depicts a gypsy woman reading the lines of a young man’s hand. This scene illustrates the ancient and enduring appeal of palmistry, the divinatory art based on interpreting the palms. A practice spanning millennia, palm reading has never truly disappeared. History.

Eastern origins: India and classical Antiquity

The roots of palmistry reach back to the ancient East. According to tradition, the art of reading hands took shape several millennia ago in the Indian subcontinent. Ancient Hindu texts associate palmistry with the Samudrika Shastra, a corpus studying the marks of the human body, with the palm (hast-samudrika) occupying an important place. From India, this divinatory practice is said to have spread to Central and East Asia, particularly China and Tibet, before reaching the Mediterranean world.

Authors of classical Antiquity also mention palm reading. The word palmistry comes from the Greek kheir (hand) and manteia (divination), suggesting that the Greeks may have been familiar with this art. Tradition holds that Anaxagoras (5th century BC) took an interest in it. A famous legend further relates that the philosopher Aristotle one day discovered a treatise on palmistry placed on an altar of Hermes, and offered it to Alexander the Great. The Macedonian conqueror is then said to have examined his officers’ hands to infer their character and destiny. Although this story is apocryphal - the text in question does not belong to Aristotle’s authentic corpus - it illustrates the ancient belief that the hand could “engrave readable characters” revealing an individual’s fate or nature.

Arab knowledge and medieval transmission to the West

After Antiquity, palmistry fades from Western sources until the High Middle Ages. It is in the medieval Arab-Muslim world that we again find practices of palm reading that would form a bridge to Christian Europe. Medieval Arab scholars classified palmistry among the popular occult sciences, alongside physiognomy (facial analysis) and astrology. In Arabic, a distinction was made between ʿilm al-kaf (“the science of the palm,” studying the shape of the hand) and ʿilm al-asārīr (palmistry in the strict sense, interpreting the lines of the hand). Although the Quran and hadiths discouraged divination, these techniques persisted in tolerated or underground forms depending on the period, forming part of the rich esoteric heritage of the medieval Islamic world. The knowledge thus accumulated would, through translations and travel, prepare palmistry’s return to the Latin West.

In Europe, palmistry resurfaced in texts around the 12th century. The English cleric John of Salisbury, in his Policraticus (1159), mentions it as a new art that had appeared in his time, evidence that the practice had only recently been introduced into Christendom. He gives an unequivocal definition: “Palmists are those who predict hidden things by inspecting the lines of the hand.” Shortly afterward, around 1160, the first Latin treatise on palmistry was written in England - possibly adapted by the itinerant scholar Adelard of Bath - and copied in the Canterbury scriptorium. This manuscript, inserted at the end of the Eadwine Psalter, attests to the recording in writing of a tradition probably transmitted orally until then. Notably, its content seems intended for a cleric, since it explains that a certain c-shaped mark at the bottom of a line on the hand foretells that a man “will become a bishop.” This early English development coincided with the first mention of a famous client: John of Salisbury reports that his correspondent Thomas Becket, then chancellor of King Henry II, consulted a palmist in 1157 before a military expedition. This anecdote shows that the art of the hand, although on the margins of official knowledge, had intrigued the powerful from the moment it appeared in Europe.

The medieval Church’s position toward these practices was critical from the outset. John of Salisbury himself, while documenting the emerging practice of palmistry, classified it among superstitious errors lacking a rational basis. In the Policraticus, he condemned the belief that “truths are hidden in the folds of the hands,” considering it unnecessary to refute by reason since “those who boast of it do not rely on reason.” Implicitly, this severity suggests that palmistry, associated with pagan divinatory arts, violated Christian orthodoxy. Over the 13th-14th centuries, the Church multiplied prohibitions against divinatory practices: councils and local synods notably denounced judicial astrology and sorcery, categories that implicitly encompassed palmistry. Despite these condemnations, palm reading continued to be practiced diffusely. It circulated in popular tales of wonder, but also within more learned esoteric currents - among certain Jewish Kabbalists of the early 13th century, who developed an esoteric palmistry connected to their mysticism of letters.

Humanist Renaissance: between occultism and learned knowledge

During the Renaissance, palmistry experienced notable growth, driven by the humanist enthusiasm for ancient occult sciences. Between the 15th and 17th centuries, numerous works devoted to it appeared in Europe, in connection with astrology and physiognomy. These treatises sought to legitimize the art of the hand by integrating it into the learned knowledge of the period, while also confronting the persistence of religious prohibitions.

From the beginning of the 16th century, publications laid the foundations for a “learned” palmistry. In Bologna in 1504, Bartolomeo della Rocca, known as Coclès, published a Compendium of physiognomy and palmistry (Chiromantie ac physionomie anastasis). In it, he combined the examination of facial features and hands to establish diagnoses concerning health and destiny, even directing his predictions at princes (Coclès thus dared to draw up a dark palmistic portrait of King Louis XII of France in his book). In 1522, the German scholar Johannes ab Indagine, a monk converted to humanist ideas, published an influential work in Strasbourg: Introductiones apotelesmaticae, a treatise merging palmistry, physiognomy, and astrology into a single system. Indagine proposed a genuine synthetic method: he assigned each mount of the hand a ruling planet, connected the morphology of the palm with the four temperaments of humoral medicine, and used the lines to detect both a person’s character and future tendencies. The ambition was to encompass the human being in their entirety - body, temperament, and astral influences - through the study of the hand. Translated into German as early as 1523 and then into French in 1556, Indagine’s book shows how this occult knowledge was received in France: it was published in Lyon by the prestigious printer Jean de Tournes and prefaced by the humanist Antoine Du Moulin, proof of Lyon’s elites’ interest in these divinatory arts.

This integration of palmistry into the knowledge of the period was accompanied by close links with medicine and astrology, disciplines that were then intertwined. Renaissance authors sought to present palmistry not as superstitious magic, but as a “natural” art based on physical correspondences. Thus, Indagine’s treatise devotes lengthy passages to the “astrological and medical rules” used to determine an individual’s state of health and the appropriate remedies according to the signs observed in their hand. The work explains, with diagrams, how an expert palmist can determine a person’s complexion and “nature” from the dominant planet indicated by their palm, then advise the physician on the regimen to follow according to the horoscope at that moment. The hand was thus regarded as a condensation of the human microcosm - “the mother of all organs, the organ of organs,” Coclès would write - whose careful examination complemented that of the pulse or urine in medical diagnosis. By blending palmistry with astrological and physiological knowledge inherited from Hippocrates and Galen, humanists hoped to elevate it to the status of an auxiliary science of medicine and the emerging study of psychology.

Despite these attempts at legitimization, palmistry remained contested and was frequently repressed during the Renaissance. From a religious standpoint, it continued to be associated with occult divination prohibited by the Church. In 1560, the Council of Trent and the Catholic Inquisition strengthened censorship of the artes magicae: palmistry was listed among the seven prohibited divinatory arts, alongside necromancy, geomancy, hydromancy, and other suspect forms of divination. As early as 1559, Pope Paul IV placed several books on palmistry on the Index librorum prohibitorum, describing them as “diabolical divinations” contrary to the faith. An author such as Indagine, although a monk, saw his treatise placed on the Index and owed his later reputation to copies discreetly preserved in princely libraries. Likewise, in 1583 the Spanish Inquisition condemned Jean Taisnier’s Opus Mathematicum (1562), which combined astrology, palmistry, and sacred arithmetic, and ordered it purged. The witch hunts then raging also fueled suspicion: people began examining the hands of accused women in search of the marks of the Devil, spots or natural signs that inquisitors interpreted as the seal of a satanic pact. Paradoxically, palmistry thus served as a tool for the very persecutions that condemned it.

However, far from disappearing, the art of the hand took root both in popular culture and among certain learned people until the classical period. In France, several works on palmistry appeared in the 16th-17th centuries, attesting to a practice straddling erudition and oral tradition. The Compendion de chiromancie by the monk Robert Fludd (1603) and the Instruction familière pour apprendre les sciences de chiromancie (1619) by the priest Jean Belot show that even clerics practiced this art, sometimes rationalizing it within an acceptable Christian framework. Under the reigns of Louis XIII and Louis XIV, the physician and philosopher Martin Cureau de La Chambre incorporated palmistry into his studies of physiognomy (L’Art de connaître les hommes, 1660), seeking to distinguish the natural reading of hands (to reveal the inclinations of the soul) from an illicit divination of the future. These “scientific” appropriations by respected authors - sometimes members of the Academy or royal physicians - reveal a degree of intellectual tolerance: stripped of its more prophetic aspects, palmistry could be reclaimed as an art of observing human temperament, akin to metoposcopy (reading forehead lines) or the phrenology that would emerge later. Nevertheless, in the dominant opinion of the Enlightenment, it remained relegated to the rank of superstition. Diderot and d’Alembert, in the Encyclopédie (1751), firmly rejected judicial astrology and, by extension, all divinations of destiny, describing them as a “ridiculous prejudice” still widespread among the ignorant. By the end of the 18th century, rationalism was in fashion, and palmistry survived chiefly in cabinets of curiosities or among fortune tellers, perpetuating a traditional skill on the margins of enlightened science.

The fortunes and misfortunes of palmistry in France

Despite its scientific disrepute, palmistry experienced a surprising revival in the 19th century, particularly in France and England. Interest in occultism, extremely strong under the Second Empire and the Third Republic, was accompanied by an attempt to scientize palm reading. In 1839, a retired French captain, Casimir d’Arpentigny, published La Chirognomonie, a foundational work that laid the groundwork for modern “chirology.” D’Arpentigny developed a systematic classification of hand types (square, conical, spatulate,...) and inferred correspondences with individuals’ abilities and character. His non-predictive approach aimed to give palmistry the appearance of an empirical discipline studying the correlation between hand morphology and personality - free from accusations of magic. Following in his footsteps, Adolphe Desbarolles, mentor of Madame de Thèbes, a French artist and esotericist, published Les mystères de la main (1869), synthesizing ancient art and contemporary observations. Desbarolles popularized the reading of the major lines (life, head, heart, Saturn,...) and minor lines, while mixing in anecdotes about the hands of famous figures of his time. Thanks to these authors, palmistry - renamed chirology - entered the fashionable salons of the 19th century. It fascinated part of the educated bourgeoisie, seeking mystery and self-knowledge in a century captivated by spiritualism. In England, the Irishman William John Warner, known as Cheiro, became the favored palmist of London’s elite around 1900, adding to the European craze.

In France, palmistry also remained firmly rooted in popular culture. Itinerant Romani people, nicknamed fortune tellers, perpetuated the practice at fairs and markets from the modern period onward, contributing to its folklore. From Victor Hugo’s gypsy woman reading Esmeralda’s hand to advertisements for female fortune tellers published in 19th-century newspapers, palm reading took its place alongside cartomancy among the divinatory arts accessible to the general public. The authorities continued to watch it with suspicion: in 1835, a French law concerning vagrancy and fraud made it possible to prosecute unregistered card readers and palmists, who were treated as charlatans. Nevertheless, these popular divinatory practices flourished even in the most remote rural areas, where fortune-telling formed part of the advice secretly sought for matters of love or fortune.

With the 20th century and the triumph of positivist science, palmistry declined as a learned form of knowledge but continued to exert a tenacious appeal. Psychiatrists and psychologists occasionally took an interest in it from the perspective of character: Carl Jung, for example, saw it as a rich reservoir of archetypal symbols, without validating its predictive claims. Overall, the scientific community now classifies palmistry among the pseudosciences, noting that no rigorous study has corroborated its principles. Nevertheless, the human hand, as an object of study, does reveal certain objective realities - signs of age, occupation, or health (calluses, tremors, coloration) - without any need to see in it a magic of destiny. It may be this element of real observation, combined with the suggestive nature of interpretation, that explains palmistry’s longevity. Between seriousness and playfulness, the “science of the hand” has reinvented itself in every era to adapt to changing mentalities. In this sense, the ancient art of palm divination remains a fascinating object of cultural history: that of a universal human practice seeking to elucidate the mystery of our destiny inscribed... in the palm of the hand.
