Who was Nostradamus really?

Michel de Nostredame, known as Nostradamus, is one of the most famous figures of the French Renaissance. Born in Saint-Rémy-de-Provence in 1503 and deceased in Salon-de-Provence in 1566, he was an apothecary, recipe writer, astrologer, almanac writer, and author of the Prophecies. His posthumous fame rests almost entirely on his quatrains, but the real man is far more interesting than the all-knowing prophet constructed by four centuries of commentary.

His era explains much of his success. In the 16th century, astrology, medicine, prognostication, and observation of the sky had not yet been separated according to modern categories. Astrological almanacs were widely read, wars and epidemics fostered a climate of uncertainty, and prophetic texts circulated widely. Pierre Brind’Amour placed Nostradamus back in this world: not as a seer isolated from his time, but as a Renaissance astrologer with a substantial literary culture and a remarkable ability to write formulations dense enough to support many interpretations.

This biography must therefore distinguish three Nostradamuses: Michel de Nostredame, the historical figure; the author of the almanacs and the Centuries; and the Nostradamus reconstructed after his death, to whom predictions about Henry II, Napoleon, Hitler, London, the world wars, and contemporary terrorist attacks would be attributed.

Birth in Saint-Rémy-de-Provence

Michel de Nostredame was born in Saint-Rémy-de-Provence on December 14, 1503. This date appears in historical works devoted to his family and in the early biographical tradition. His father, Jaume de Nostredame, belonged to a family of notaries and merchants. His mother, Reynière de Saint-Rémy, also came from an established family in Provence.

The National Library of France describes him as a physician, botanist, and astrologer. The word “Nostradamus” corresponds to the Latinized form of his name, a common practice among Renaissance men of letters. Nostradamus’s paternal family did indeed have Jewish origins and later converted to Christianity.

Research by E. P. E. Lhez in Provençal archives shows that Michel’s father and uncle appear among Christians from Jewish families converted less than fifty years earlier. This ancestry is historical. The tradition that traces him back to the biblical tribe of Issachar emerged later and belongs to the esoteric interpretation of his lineage.

Pierre-Joseph de Haitze asserted this in 1712, nearly a century and a half after Nostradamus’s death, relying on sources he did not document precisely. Nevertheless, it reveals how posterity associated his prophetic gift with a renowned biblical lineage believed capable of discerning the times and signs. Jean-Aimé de Chavigny, Nostradamus’s secretary and first major biographer, claimed that one of his maternal ancestors had given him an early taste for the “celestial sciences.”

This testimony was published in 1594, twenty-eight years after Nostradamus’s death. It may preserve a family memory, but it also contributes to constructing a learned genealogy intended to present the prophet as the natural heir to ancient knowledge. It is therefore prudent not to turn his maternal grandfather into an unquestionable master of medicine, Hebrew, Greek, and astrology without stronger contemporary documentation.

Studies in Avignon

As an adolescent, Nostradamus went to Avignon to study. There he pursued the liberal arts, mainly grammar, rhetoric, logic, and philosophy. An epidemic interrupted university activities and forced him to leave the city before completing this course of study. His subsequent years are less well documented. In his own writings, he claims to have traveled through French regions in search of plants and remedies.

During the 1520s, Nostradamus worked as an apothecary. This activity involved preparing and selling medicines, compounds, perfumes, and various substances. It required genuine knowledge of medicinal plants, raw materials, and preparation methods. An apothecary was not, however, a university-trained doctor of medicine. This distinction became decisive when he presented himself at Montpellier.

On October 3, 1529, Michel de Nostredame enrolled in the Faculty of Medicine at Montpellier. The university register preserves an exceptional document: Guillaume Rondelet, then the students’ prosecutor, crossed out his enrollment after learning that he had practiced as an apothecary, a manual occupation forbidden by the statutes to candidates for this program. The document also mentions remarks hostile to doctors. This expulsion is one of the few directly documented university facts from his youth. The answer remains uncertain. Nostradamus was later described as a “doctor of medicine” in several publications and by his contemporaries. His Opuscule of 1555 presents him as such.

But no clearly preserved doctoral diploma demonstrates that he completed the Montpellier course after his expulsion. Historians have proposed several scenarios: temporary exclusion, a later return, a degree obtained elsewhere, or simply the social use of a medical title. A rigorous biography must preserve this uncertainty.

Nostradamus and Plague Epidemics

Nostradamus's medical career is strongly associated with epidemics. He worked in several cities affected by contagious diseases, particularly in Provence. His posthumous reputation turned him into an extraordinarily modern physician who supposedly understood hygiene, prohibited bloodletting, required clean water, and saved thousands of people. The sources do not support going that far.

Plague remained poorly understood in the 16th century. The bacterium responsible would not be identified until the end of the 19th century. Renaissance physicians still worked with humoral theories, miasmatic conceptions, and plant-based or compound remedies. Nostradamus belonged to this world. He prepared medicines, perfumes, powders, and lozenges, but nothing demonstrates that his treatments effectively protected against plague.

Recent works of medical history recognize its place in the history of health practices, while recalling that he remains a physician of his time, not a forerunner with a microbiological understanding of contagion. A rose-based preparation is frequently associated with Nostradamus. It belongs to the world of aromatic remedies and substances reputed to purify or protect against miasmas.

Its historical interest is real: it shows the role of perfumes, plants, and fragrant preparations in plague medicine. It should not be presented as a medicine whose effectiveness against Yersinia pestis had been demonstrated.

At the beginning of the 1530s, Nostradamus stayed in Agen, where the humanist and physician Julius Caesar Scaliger lived. Their relationship has been embellished by several biographies, which portray Scaliger as a direct master or a lasting protector.

What is certain is that Nostradamus was then part of a humanist milieu where medicine, philology, and classical culture intersected. The relationship between the two men later deteriorated. Nostradamus married in Agen and had two children. The name of his first wife remains disputed. “Henriette d’Encausse” appears in several biographies, but the documentation does not allow this name to be treated as definitively established.

His wife and two children died in the 1530s. The plague is regularly cited as the cause, but contemporary sources do not establish this with certainty. After this family loss, Nostradamus left Agen. He traveled through France and, according to several traditions, Italy. The routes proposed by biographers do not all have the same level of evidence. This period helped shape the image of the traveling physician gathering plants, recipes, astrological observations, and local knowledge. Above all, it preceded his permanent settlement in Provence.

1547, settling in Salon-de-Provence

In 1547, Nostradamus settled in Salon-de-Provence. The city still preserves his house, now a municipal museum. The municipality notes that he founded a new family there with Anne Ponsarde. The couple would have six children. Salon became the center of his intellectual and professional life until his death.

Anne Ponsarde belonged to a family established locally. With her, Nostradamus built a stable home, far removed from the image of the solitary prophet shut away in his tower. Their son César de Nostredame would become a poet, historian, and painter. Around 1614, César produced the portrait of his father that is now the best known.

In 1555, the Excellent & moult utile opuscule, known today as the Traité des fardements et confitures, was published in Lyon. The Bibliothèque nationale de France preserves a copy of this edition.

The book brings together recipes for cosmetics, fragrances, food preparations, and preserves. This book reminds us that Nostradamus did not write solely about the future. He was fully part of the practical culture of the Renaissance, in which medicine, cooking, perfumery, and pharmacy overlapped.

The almanacs, the true driving force behind his fame

Before the Centuries, Nostradamus became famous through almanacs and annual prognostications. He published them from 1550 onward and continued this activity almost until his death. These works contained weather forecasts, political observations, astrological configurations, and omens for the year. They reached a much wider audience than the readers of his most obscure quatrains.

Nostradamus also worked for individual clients. Some of his astrological correspondence has survived. It shows that he calculated nativities and interpreted charts for high-ranking figures.

In a letter, he mentions, for example, the work carried out for the nativity of Charles IX. It is therefore more accurate to present him as a professional astrologer than as an isolated prophet receiving only visions.

Pierre Brind’Amour studied Nostradamus’s astrological calculations in detail. His analysis shows that the man was well acquainted with the vocabulary and methods of the astrology of his time, but that he also made errors in coordinates, house division, and astronomical calculation.

His success therefore did not stem from exceptional mathematical perfection. It came largely from his writing, his sense of imagery, and his ability to express the collective anxiety of his time. The link between medicine and astrology was not unusual then. Many physicians took celestial configurations into account when choosing treatment dates, interpreting crises, or reflecting on epidemics.

The academic review of Nostradamus astrophile recalls that at the time of Nostradamus’s death, astronomy, astrology, and medicine were still closely associated. Our article Understanding divination through the ages places judicial astrology within this history.

1555, the first Centuries

In 1555, the Lyon printer Macé Bonhomme published the first edition of the Prophecies. Contrary to the current image of a book that immediately contained ten complete centuries, this first edition contains 353 quatrains. Pierre Brind’Amour established the modern critical edition. The texts are preceded by a letter addressed to César, Nostradamus’s young son.

A new edition appeared in 1557 through Antoine du Rosne. The surviving copies contain 639 or 642 quatrains, depending on the print run. The transmission of the text was therefore complex from the earliest years. Later editions added further collections.

The 1568 edition published by Benoist Rigaud, two years after Nostradamus’s death, contains 942 quatrains. It best corresponds to the modern image of the ten Centuries. Even so, not all the centuries contain one hundred quatrains. Speaking of “a thousand prophecies” is therefore an oversimplification.

The quatrains combine Renaissance French, Latinisms, geographical names, ancient references, martial imagery, and deliberately compact formulations. Anna Carlstedt has shown that their interest cannot be reduced to the search for a prophetic “key”: they must also be read as a form of 16th-century oracular poetry. This dense language produces a text that resists a single interpretation. It is precisely this resistance that would allow later generations to project events very far removed from their own time onto it.

Modern philological research has identified numerous borrowings or parallels with ancient, biblical, and historical texts. Jean-Paul Clébert aptly summarizes this method: Nostradamus regularly seems to recompose past events into images that could be read as the future.

This practice was not an exceptional fraud for its time. Renaissance prophetic texts readily used biblical typology, historical repetition, and analogy. The future was then understood as the repetition or transformation of events already inscribed in history.

The stay at court in 1555

The publication of the Prophecies and the success of the almanacs attracted the court’s attention. Nostradamus went to see Henri II and Catherine de’ Medici in 1555. Later accounts readily present this meeting as the prophet’s absolute triumph. The work of Brind’Amour and studies of the prognostications call for greater caution: the court was interested in his predictions, but also concerned by certain political formulations.

Catherine de’ Medici is the great patron associated with his memory. She was interested in astrology and commissioned works concerning the destiny of her children. Nostradamus was received several times in the royal circle. This proximity greatly enhanced his reputation: an astrologer consulted by the queen mother immediately gained an authority that almanacs alone could never have provided.

In 1564, the young Charles IX and Catherine de’ Medici passed through Salon-de-Provence during the great royal journey across France. Nostradamus was received in this context and met with the king.

Court sources subsequently describe him as an adviser and ordinary physician to Charles IX, a position that was mainly honorary toward the end of his life. This official recognition marked the height of his career.

Did he really predict Henri II’s death?

Quatrain I, 35 has become the most famous proof of his prophetic power. It evokes a “young lion,” an “old” one, a “single duel,” a “golden cage,” and a cruel death. Henri II died in 1559 after a lance splinter struck him in the eye during a tournament against Gabriel de Montgomery. The connection seems spectacular when the event is already known.

The quatrain clearly predates the king’s death, ruling out a forgery written after 1559. But several details of the modern interpretation were reconstructed after the fact. There is no proof that Henri II and Montgomery had been identified before the tournament as the “old lion” and the “young lion.” The royal helmet is not simply a “golden cage,” and the meaning of “two classes one” remains debated.

Above all, no solid contemporary source shows that the quatrain had been publicly recognized before the accident as a precise prediction of Henry II’s death. It is therefore a good example of retrospective reading: a vague text acquires new precision once the event is known.

Napoleon and the French Revolution

Many quatrains have been applied to the French Revolution and then to Napoleon. The methodological problem remains the same: the associations become famous after the events. A quatrain describing an emperor near Italy may seem to refer to Napoleon to a 19th-century reader, but Nostradamus’s Europe already knew the Italian Wars, emperors, princes, and dynastic upheavals. The text’s strength comes from the possibility of reusing its images in new contexts.

A quatrain referring to London, fire, and the numbers twenty-three and six is regularly associated with the Great Fire of 1666. Interpreters have searched these numbers for operations that could produce 1666. But the text does not explicitly give that year in a clear form. The connection becomes convincing mainly because the reader already knows about the fire.

Nostradamus never writes the name Hitler. The word “Hister” appears in certain quatrains and was associated with Hitler in the 20th century. However, Hister is an ancient geographical name for the lower Danube used in ancient and Renaissance texts. Turning every occurrence of Hister into Adolf Hitler is therefore an anachronistic reading.

Nostradamus’s reputation experiences a new expansion during the Second World War. Propagandists use or fabricate interpretations of his quatrains to support political narratives about the outcome of the war.

This story shows how an obscure work can be mobilized when societies are going through a crisis. The phenomenon is not new: editions and commentaries on Nostradamus regularly resurface during periods of war, revolution, or catastrophe.

During every major contemporary crisis, texts circulate under his name. Some do not appear in any authentic edition of the Prophecies. The mechanism is simple: a few lines written in an archaizing style are attributed to Nostradamus, then shared as if they came from the 16th century. Before interpreting a prophecy, the first step should therefore always be to verify that it actually exists in an old edition. Nostradamus does not present himself simply as an astrologer mechanically calculating the future. In the epistle to Caesar, he mentions the “nocturnal and celestial lights” and the “spirit of prophecy.”

He thus combined natural astrology, prophetic inspiration, and references to the ancient tradition. This ambiguity was part of his success: he was enough of an astrologer to seem learned and enough of a prophet to go beyond the limits of calculation.

Did Nostradamus practice magic?

The word itself also requires some nuance. Nostradamus was familiar with ancient texts and divinatory traditions, but his documented activity focused mainly on astrology, almanacs, prognostications, and recipes.

His surviving work does not show him practicing ceremonial magic in the manner of an Cornelius Agrippa; his occultism mainly took the form of astrology, calculations, signs, and prophetic inspiration. This does not erase his occult aura: astrological calculation, prophetic inspiration, symbolism, and deliberately obscure language constantly come together in Nostradamus.

Almanacs and prognostications enjoyed considerable success. They were translated, imitated, counterfeited, and published under his name, sometimes without his consent. Nostradamus's fame therefore did not begin after his death. During his lifetime, he already had an international clientele and an editorial brand powerful enough to attract forgers.

Jean-Aimé de Chavigny worked with Nostradamus during the final years of his life. After his death, he became one of the first architects of his legacy. In 1594, Chavigny published La première face du Janus françois, in which he linked Nostradamus's texts to historical events that had occurred since their publication. This approach inaugurated a method that would become central: searching retrospectively for the event corresponding to the quatrain.

Nostradamus suffered from gout, a disease that progressively limited his mobility. During his final years, however, he continued to write, correspond, and receive visitors. He drew up his will in June 1566. Death approached in the context of health that had already been deteriorating for several years.

Died on July 2, 1566

Michel de Nostradame died in Salon-de-Provence on July 2, 1566. The date is confirmed by several historical studies and by Provençal documentation. He was sixty-two years old. The famous claim that he told his secretary that he would not be found alive at sunrise belongs to biographical tradition and does not have the same level of evidence as his will or his date of death.

Several texts were attributed to him after the fact to prove that he knew the exact date of his death. As with Henry II, the difficulty lies in retrospective selection. An elderly, sick astrologer suffering from gout could write about his death or predict a worsening condition without possessing supernatural knowledge of the exact time. The legend of the last prophecy belongs above all to the posthumous construction of the character.

Nostradamus was initially buried in the church of the Cordeliers convent in Salon. His tomb quickly became a place associated with his memory. His son César and his admirers helped cultivate the image of an extraordinary man. The French Revolution directly affected his burial place.

The City of Salon-de-Provence confirms that in 1791, National Guardsmen from a battalion from Marseille desecrated the tomb in the Cordeliers convent. The mayor, Jean André David, then had the remains of Nostradamus, along with his portrait and that of his son César, transferred to the Saint-Laurent collegiate church.

This transfer is therefore historical. A famous legend claims that when his tomb was opened in 1791, soldiers discovered a plaque on the skeleton bearing precisely the year of the desecration. The city confirms the desecration and the transfer of the remains, but not this spectacular prophecy. The prophetic plaque must therefore remain in the realm of legend.

Why do his quatrains remain so effective?

Their power comes from several characteristics. They are short, vivid, and loosely dated. They use wars, plagues, fires, princes, cities, rivers, famines, and political upheavals: events that recur throughout history. Readers can therefore easily connect a new catastrophe with an image that is several centuries old.

The prophetic reputation also rests on a simple mechanism: similarities are remembered, while the thousands of lines that do not correspond to any remarkable event are forgotten. Interpreters can also change the translation, the way words are divided, or the identities of the characters to improve the match. A genuinely precise prediction should be understandable before the event, not only afterward. The Centuries rarely withstand this test.

The best way to read it is not to search each quatrain for the next global event. His texts are major documents on the fears, expectations, and astrological culture of the Renaissance.

They also reveal an author capable of condensing historical and ancient references into extraordinarily enduring poetic images. Reading Nostradamus historically does not diminish his interest; on the contrary, it makes it possible to understand why his texts survived while so many almanacs of his time disappeared.

Sources and reference points

The Bibliothèque nationale de France confirms Nostradamus’s identity as Michel de Nostredame, born in 1503 and deceased in 1566, and describes him as a physician, botanist, and astrologer. It preserves a very large number of editions of his works.

The fundamental critical edition on the beginnings of the Centuries is Pierre Brind’Amour, The First Centuries or Prophecies: The 1555 Macé Bonhomme Edition, Droz, 1996. The BnF confirms that this first edition contains 353 quatrains.

Pierre Brind’Amour, Nostradamus astrophile, Presses de l’Université d’Ottawa / Klincksieck, 1993, remains the major study of his astrology. A review published in Provence historique highlights the precision with which the author places Nostradamus in the world of Renaissance astrologers while also showing the calculation errors in his horoscopes.

Anna Carlstedt, The Oracular Poetry of Nostradamus, studies the language, style, and genre of the Centuries. Her work confirms the major textual stages: 353 quatrains in 1555, approximately 640 in 1557, and 942 in the 1568 edition.

Denis Crouzet, Nostradamus: A Medicine of Souls in the Renaissance, places the author within the religious and political culture of the mid-16th century. The Presses universitaires de Provence point out that his Prophecies must be understood within the anxious atmosphere of an era when astrological and prophetic discourse was widely disseminated.

The Nostradamus House in Salon-de-Provence preserves the material memory of his second family life, his works, and the house he purchased in 1547. The town also documents the transfer of his remains after his tomb was desecrated in 1791.
