The flickering torches of Richmond Palace cast long, distorted shadows against the stone walls, dancing like specters in the corridors where the heavy scent of incense struggled to mask a more metallic, cloying odor. It was the winter of 1513, and the air inside the Queen’s chambers was thick with a silence so heavy it felt like a physical weight. Outside, the world believed a royal heir was being born—the future of the Tudor line, the hope of a king who viewed his own virility as a divine right. But inside, the scene was a descent into a waking nightmare. There were no joyful cries, no hurried whispers of “a prince.” Instead, there was the sound of a seasoned physician, a man who had seen the carnage of battle and the rot of the plague, dropping a silver basin as he recoiled in visceral, primal terror.
Some were buried at midnight in graves with no names, the earth packed down in frantic haste before the first light of dawn could expose the truth to a prying court. Others were erased from every document that ever recorded their existence, their names struck through with heavy ink or their birth records fed to the ravenous fires of the Queen’s hearth. The pregnancies of Catherine of Aragon produced children so disturbing that eyewitnesses were paid small fortunes—sums that could buy entire manors—to take what they saw to their graves. They were bound by oaths that tasted of copper and fear. By the time this narrative concludes, you will understand the harrowing medical reality of what was happening to these infants and the shocking, hidden truth of where the missing bodies actually ended up.
The records that somehow survived the systematic purge tell a chilling story of a dynasty at war with its own biology. Within hours of certain royal births at Richmond Palace in Greenwich, servants received frantic, whispered orders to feed specific documents to the fires burning in the Queen’s chambers. They watched as vellum curled and blackened, carrying the secrets of the Tudor bloodline into the chimney soot. But fire is an imperfect destroyer; it leaves behind fragments, charred reminders of things that were never meant to be remembered. A fragment recovered centuries later from the structural remains of Richmond Palace contained three words scratched in hurried, trembling Latin by a court physician:
“Contra naturam natus.”
Born against nature.
What could have been so profoundly disturbing that trained medical professionals, men who had witnessed death and disease in every conceivable form, would abandon clinical language entirely and reach for the vocabulary of the supernatural? The answer begins with a grim understanding: Tudor physicians were not strangers to tragedy. They had attended stillbirths and infant deaths throughout their entire careers. They possessed a detailed, if rudimentary, terminology for birth defects, premature delivery, and maternal complications. They knew the look of a child taken by the cord or a babe too small for this world.
Yet, when it came to certain of Catherine’s children, they discarded that vocabulary. They turned instead to the language of demonic aberration, of cosmic wrongness. This was not the product of simple ignorance or peasant superstition. These were the most educated men in the realm, struggling to describe something their years of university training and anatomical study had left them completely unprepared for. The trauma was so acute that court records reveal a startling trend: after certain births, multiple physicians submitted immediate, desperate requests for transfer to other noble households. They were willing to abandon prestigious positions at the royal court, forfeiting proximity to power and wealth, with no explanation given other than a desperate need to be elsewhere.
One physician in particular, Thomas Linacre—the man who had founded the College of Physicians and served as Henry VIII’s personal doctor—abruptly withdrew from court life after attending one of Catherine’s deliveries in 1513. A man at the pinnacle of his profession, he never practiced medicine again. He retreated into a silence that lasted until his death, a man haunted by a sight that no amount of medical logic could erase.
The apparatus of secrecy surrounding these births was systematic, cold, and extraordinarily costly. The Crown did not merely ask for silence; it purchased it. Midwives received payments ranging from 50 to 200 pounds—staggering fortunes at a time when a skilled craftsman might earn only 10 pounds in an entire year. These transactions appear in fragmentary financial records, hidden under vague, sterile descriptions such as “for services rendered to her majesty” or “for discretion in royal matters.” Yet, when historians overlay these payments with the known timeline of Catherine’s failed pregnancies, the synchronization is haunting.
The speed with which physical evidence was eliminated suggests a level of panic that went far beyond ordinary royal privacy. When Catherine’s pregnancies ended badly, the response was not one of mourning, but of erasure. Entire rooms would be gutted, the tapestries ripped down and the furniture removed as if to purge a contagion. Birthing chairs, usually prized heirlooms, were burned rather than stored. Linens and blankets, even those embroidered with gold thread, were destroyed rather than laundered and reused—a shocking waste in an era where even royal households practiced a degree of thrift.
Most tellingly, the household accounts show unusual, urgent orders for quicklime in the immediate aftermath of certain births. In Tudor England, quicklime served one primary, grim purpose: the rapid decomposition of organic matter. It was used in plague pits to ensure the dead did not linger. Its presence in a royal birthing chamber suggests a desperate need to make something disappear—not just to bury it, but to unmake it.
What makes this conspiracy of silence even more disturbing is its international reach. Foreign ambassadors stationed in England were the eyes and ears of the world’s most powerful monarchs. Their professional function was to report every cough, every whisper, and every pregnancy at court back to their home governments. Their letters still survive in archives across Europe, from the Vatican to Venice. A Venetian ambassador, in a coded dispatch from 1514, referenced an event of such a nature that he dared not commit the full details to paper, even in cipher. He wrote of a “shadow over the cradle” that defied description.
The Spanish ambassador, who had direct access to Catherine and was there to serve her homeland’s interests, wrote to the successors of Ferdinand and Isabella. He described a tragedy that went beyond any normal understanding of birth complications. These were seasoned diplomatic observers who had navigated the bloody, scandalous courts of the Borgias and the Valois. They were not men easily unsettled. Yet, something about Catherine’s situation left them unable or unwilling to write specifics, even in private, encrypted correspondence. The silence was international, coordinated, and absolute.
But silence creates gaps, and gaps create questions that echo through the centuries. By 1516, when Catherine finally delivered a living child, Princess Mary, the relief at court was not simply about securing the succession. It was a collective exhale of breath from a court that had been holding its collective lungs for six years. It was about proving that Catherine could produce something normal—something that could be acknowledged openly, held in the light, and celebrated without the shadow of the “unnatural.”
But that relief would not last. Whatever was causing these catastrophic outcomes was not gone; it was latent, intensifying like a gathering storm. And what happened in Catherine’s next pregnancy would make all the previous horrors seem almost bearable by comparison.
The pattern began slowly, then repeated with terrifying, metronomic regularity. Catherine of Aragon’s first pregnancy came in early 1510, shortly after her vibrant marriage to the young Henry VIII. The Queen was 24 years old, healthy by every account, and hopeful about producing the male heir Henry desperately needed to solidify his father’s relatively new dynasty. But in January 1510, just months into the pregnancy, Catherine miscarried. The official announcement was brief and deliberately vague, stating only that the Queen had lost the child and was recovering. No details followed. There was no indication of how far along she was, what caused the loss, or whether the fetus displayed any abnormalities. At the time, this appeared to be ordinary royal discretion. In reality, it established a blueprint for the decade of tragedy to follow.
Eleven months later, in January 1511, Catherine gave birth to a living son. He was named Henry, Duke of Cornwall. For 52 days, England had its male heir, and the King was transformed by a manic, almost desperate joy. The celebrations were enormous—tournaments were held where Henry rode as “Sir Loyal Heart,” church bells rang throughout London, and wine flowed in the streets. Then, the infant died. The cause was recorded simply as infant mortality, a broad term in Tudor times that could encompass almost anything from SIDS to infection.
What followed, however, was strange. Tradition required a prince’s body to lie in state, allowing the nobility to pay their respects. Instead, the funeral was rushed, conducted within 24 hours with minimal attendance and no public viewing of the body.
“Why the hurry?”
Whispered a courtier in a letter that was quickly suppressed.
“Why the secrecy for a prince of the blood?”
Infant death was a common tragedy in the 16th century; there would have been nothing to hide unless there was something very specific about this infant—something that manifested in his final hours—that needed to be hidden from the eyes of the realm.
Between 1511 and 1514, Catherine had two further known pregnancies. The first, in late 1513, ended in a stillborn son delivered in December. Court records indicate the Queen was devastated, but once again, details are conspicuously absent. The second pregnancy in 1514 ended identically: another stillborn child in late December. Two consecutive December stillbirths, both sons, both buried rapidly and with minimal ceremony. The timing alone aroused suspicion. December births implied conception in March or April, meaning these pregnancies had progressed nearly to term before ending in death.
The Venetian ambassador wrote that the household staff appeared frightened and deeply reluctant to discuss what had occurred in the birthing chamber. The French envoy noted that the Queen’s ladies-in-waiting received unusually generous gifts following the 1514 stillbirth—the kind of payments that bore the unmistakable scent of hush money. Most revealingly, the Spanish ambassador, who had previously been Catherine’s most vocal supporter, stopped referencing her pregnancies in his correspondence after 1514 entirely. It was as if he had seen something that convinced him there was no longer any hope to be found in her womb.
Then came 1516, and finally, a fragile success. Catherine delivered a living daughter, Mary, on February 18th. The relief at court was palpable. Even though the child was female and Henry had wanted a son, Catherine had at least proven she could carry a pregnancy to term and produce a child that lived. Princess Mary was healthy and normal in every respect. But that single success was surrounded by failure on every side—a failure that was becoming impossible to ignore.
In 1518, Catherine became pregnant for what would be the final time. She was 33 years old. In November of that year, she delivered a stillborn daughter. This time, there was no public announcement at all. The birth went entirely unrecorded in official chronicles. We know about it only through private correspondence between Henry’s closest advisers and fragmentary traces in household accounts. The baby’s body was never placed in any royal tomb. No record survives of where or how it was buried. It simply disappeared from history as though it had never existed.
Six pregnancies in eight years. One living child. Five dead.
What makes Catherine’s reproductive history truly disturbing is not the failure rate itself—many women of the era suffered similar losses. It is what happened to the bodies of those dead children and what the people who witnessed those births were forbidden to ever say aloud. Because by 1518, the whispers circulating through Europe’s courts had taken on a specific and horrifying character. People were no longer simply murmuring about stillbirths. They were whispering about monsters.
The birth that truly changed everything—the one that broke the spirit of the physicians—occurred in the winter of 1513. Catherine was eight months along, and the court physicians were cautiously hopeful when labor began in early December. But something went wrong almost immediately. The labor was punishing, lasting over 18 hours, and Catherine’s cries were said to be so harrowing they could be heard throughout the palace, echoing off the cold stones.
When the child was finally delivered, those waiting in the outer chambers reported an unusual, terrifying response from inside the birthing room. It was not the recognizable sounds of grief over a stillborn—the weeping or the prayers. It was something else entirely. There was a stunned, absolute silence. Then, frantic whispered conversations. Then, the unmistakable sound of someone being violently ill.
Three midwives had been present along with two physicians. Within an hour of the delivery, one of the midwives was removed from the palace, physically carried away by guards while she wept uncontrollably, her mind seemingly shattered. The senior midwife, a woman named Agnes, remained, but she refused to speak about what she had witnessed for decades.
It was only years later, on her deathbed in 1563, that she finally broke her silence in a confession to a priest. That priest’s personal writings survived, concealed in church archives for centuries, escaping the Tudor purges. According to the priest’s account:
“Agnes described the 1513 stillbirth as an infant whose form was not as God had intended.”
She said the child had been full-sized and fully formed in most respects, but with abnormalities so severe that everyone in the room understood immediately why it had not survived. She described a skull that was not properly closed and limbs that were “not right,” twisted in ways that defied the natural order.
Modern medical historians, reading this centuries-old account, believe she was describing severe neural tube defects, possibly anencephaly—a condition in which the brain and skull fail to develop correctly. Infants born with these conditions rarely survive more than hours after birth, and in Catherine’s case, the child was already dead at delivery.
Agnes also noted that this was not the first time she had witnessed such abnormalities in royal births, and she feared it would not be the last. She specifically mentioned attending Catherine again in 1514 and encountering similar malformations, though of a different character.
In the 16th century, neural tube defects could stem from various causes—folic acid deficiency, genetic predisposition, or exposure to toxins. But in Tudor England, none of these causes were understood. This lack of knowledge created a question that was impossible to suppress: Was Catherine cursed? Or was something wrong with the royal bloodline itself?
The religious interpretation of Catherine’s reproductive failures became impossible to ignore by 1527, when Henry VIII began seriously pursuing an annulment. His argument, presented to the Pope, centered on a passage from Leviticus: “If a man shall take his brother’s wife, it is an unclean thing… they shall be childless.”
Catherine had previously been married to Henry’s older brother Arthur, who died in 1502. Henry declared their marriage had been cursed from its very beginning, and Catherine’s dead children were proof of divine displeasure. Catherine could conceive easily; she had done so at least six times. But she could not carry healthy children to term, except once.
To the Tudor mind, this did not look like bad luck. It looked like divine judgment. And if God was punishing this marriage, then the physical form of that punishment—the dead and deformed infants—were understood as signs and warnings from the Almighty. This interpretation directly shaped how the bodies were handled. Children perceived as evidence of a divine curse could not be given proper royal funerals, nor buried in consecrated ground in prominent locations. They had to be hidden. They were interred quietly, their existence minimized or erased from the official record to prevent the public from seeing the “evidence” of God’s anger.
Physical evidence that has outlasted the centuries tells a different story. Peterborough Cathedral is the true burial place of Catherine of Aragon, where she was laid to rest on January 29th, 1536. Henry VIII ordered she be buried not as a Queen, but as “Princess Dowager of Wales,” a title Catherine had always refused to accept. Her tomb is marked today by a simple stone slab.
But it is Westminster Abbey that holds the most troubling connection to Catherine’s story. Architectural surveys conducted in the 19th century revealed at least three small, unidentified burial sites in areas of the Abbey associated with Tudor infant burials. These anonymous infant interments were set deeper than normal, placed in simple wooden coffins rather than the lead-lined caskets used for royalty. They were positioned away from the main family groupings—present, but entirely unacknowledged.
Westminster Abbey officials have refused all requests to investigate these sites, citing preservation concerns and respect for the dead. If modern forensic technology could examine those remains, it might finally answer questions that have haunted historians for 500 years. Were these children showing evidence of genetic disorders? Are there patterns of skeletal abnormality pointing to specific medical conditions? The answers may be there, sealed beneath the stone.
Secret burials were not limited to Westminster. Research into parish records around London and royal residences has uncovered suspicious gaps and irregularities. At Greenwich Palace Church, records show a payment for the burial of a royal infant in 1514, but no corresponding entry exists in the burial register itself. At Richmond Palace, a churchwarden’s personal account book from 1515 mentions providing materials for the “quiet burial of a child of royal blood” in December of that year, yet no royal birth is recorded that month in any official chronicle.
Even more unsettling are documents connected to Hampton Court, which reference an infant of noble birth buried beneath a chapel floor at night in 1513. The entry states that the burial was conducted with all Christian rites, but without public observation, noting:
“The child’s appearance made a closed casket service necessary.”
A dispatch from the Spanish ambassador to King Ferdinand in 1514 states that the Queen had been delivered of another child that did not live, adding that:
“The circumstances were such that he could not detail them in writing even to his sovereign, but would report in person at the earliest opportunity.”
This is extraordinary. What could be so disturbing that it could not be set down even in a confidential dispatch to a King? The French ambassador, writing to Francis I, mentioned that rumors of “unfortunate peculiarities” surrounded Catherine’s failed pregnancies, suggesting that matters of state security were involved. Why would stillbirths be classified as matters of state security? Unless, of course, what they revealed was politically dangerous—something that could be weaponized against Henry’s claim to the throne.
We must discuss what modern medicine tells us was actually happening inside Catherine of Aragon’s body, because the truth is less supernatural, but perhaps more tragic than Tudor observers ever imagined. The leading medical theory among historians who have studied Catherine’s case is Rh blood incompatibility.
This condition was not discovered until 1940, but it explains her pattern of pregnancies with devastating precision. Blood types include not just A, B, AB, and O, but also a marker called the Rh factor, which can be positive or negative. If a mother is Rh negative and the father is Rh positive, their children have a 50/50 chance of being Rh positive. During pregnancy, a small amount of the baby’s blood can cross into the mother’s bloodstream. If the baby is Rh positive and the mother is Rh negative, her immune system identifies the baby’s blood cells as foreign and begins producing antibodies against them.
This typically has limited impact on the first pregnancy because the antibody buildup takes time. But in subsequent pregnancies, if the baby is again Rh positive, the mother’s immune system is already primed and attacks the infant’s blood cells aggressively. This is called hemolytic disease of the newborn, and it deteriorates with each successive pregnancy.
The first baby might be healthy. The second might present with mild anemia. By the third, fourth, fifth, and sixth pregnancies, the babies frequently die in utero or are born so severely affected that survival is impossible. This matches Catherine’s pattern exactly.
Her first recorded pregnancy ended in miscarriage. Her second produced Prince Henry, who was born alive but died at 52 days. Infants with hemolytic disease often appear healthy at birth before declining rapidly as complications take hold. The third and fourth pregnancies ended in stillbirths, increasingly likely as antibody levels escalated. Then came Mary in 1516.
Why did Mary survive?
Possibly because Mary was Rh negative like her mother, meaning no blood type conflict existed. Catherine’s final pregnancy in 1518 ended in stillbirth—almost certainly another Rh positive child overwhelmed by the massive antibody load now present in Catherine’s system.
But here is where the medical explanation becomes truly disturbing. Severe hemolytic disease does not merely kill. It causes specific, visible physical abnormalities. Babies with this condition frequently develop hydrops fetalis, a condition in which fluid accumulates throughout the body, producing severe and widespread swelling. They can appear grotesquely enlarged with distended abdomens, distorted features, and skin that takes on disturbing coloration—yellow or even greenish from profound jaundice. Their skulls can appear misshapen from fluid accumulation and brain damage. Their internal organs, especially the liver and spleen, become massively enlarged and can be visible through the stretched skin of the abdomen.
If you were a Tudor midwife or physician, and you delivered an infant with severe hydrops fetalis, what would you see? You would see a child monstrously swollen with discolored skin and a grotesquely enlarged belly. You would have no framework to understand this was a blood disorder. You would only know that the baby looked “unnatural” and “cursed.” The Latin phrase “Contra naturam natus” makes complete sense in this context. The physicians were describing what they saw as accurately as their knowledge allowed.
There is another medical theory that some historians consider even more disturbing—one that points the finger not at Catherine, but at Henry VIII himself. Evidence suggests Henry may have been infected with syphilis, possibly from early in his adult life. Syphilis was epidemic throughout Europe during this period, frequently called the “Great Pox,” and it was not uncommon among nobility who maintained multiple partners.
If he contracted the disease and transmitted it to Catherine, it would explain her reproductive catastrophes with brutal clarity. Congenital syphilis, passed from mother to infant during pregnancy, produces a horrific range of birth defects. Infected infants may be stillborn or die shortly after delivery. Those who survive often present with severe abnormalities: skeletal deformities affecting the skull, skin lesions, enlarged livers, and profound neurological damage.
Infants with congenital syphilis can develop what is known as “saddle nose deformity,” in which the nasal bridge collapses and the face takes on a disturbing flattened appearance. They may develop “saber shins,” where the bones of the lower legs bow grotesquely outward. Their skulls can show severely abnormal development with prominent, misshapen foreheads.
The syphilis theory draws support beyond Catherine’s failed pregnancies alone. Henry’s later wives also struggled to carry pregnancies to term. If Henry was the source of infection, it would explain why multiple, entirely different women all experienced comparable reproductive failures when married to him. Henry’s own health problems in later life—the leg ulcers that never healed, the dramatic personality shifts, the violent mood swings—are all consistent with tertiary syphilis.
Tudor physicians would have recognized syphilis in adults; they treated it with mercury, which Henry is known to have received. But they may never have connected the King’s disease to the Queen’s reproductive failures, particularly since drawing that connection would have been political suicide. If this theory is correct, the truly terrifying aspect of the cover-up is not what it was hiding about Catherine—it is what it was hiding about the King. The deformed infants were physical proof that something was corrupted at the heart of the Tudor dynasty.
By 1527, Catherine of Aragon was 42 years old and had not been pregnant for nine years. Henry’s patience had been exhausted. He wanted a son, he wanted Anne Boleyn, and he wanted Catherine gone. The annulment proceedings were a slow-motion car crash of theology and politics. The Pope delayed for six years, caught between Henry and Catherine’s powerful nephew, the Holy Roman Emperor.
Catherine fought to preserve her marriage throughout all of it, because she understood that if the marriage were annulled, her daughter Mary would be declared illegitimate and stripped from the succession. The final humiliation came in 1533, when Henry broke from Rome entirely and annulled his own marriage. Catherine was stripped of her title as Queen and reduced to “Princess Dowager.” She was separated from Mary and relocated to a succession of increasingly remote and uncomfortable residences.
Out of six wives and numerous known pregnancies, Henry VIII produced just three living children who reached adulthood: Mary, Elizabeth, and Edward. This extraordinarily low success rate across entirely different women is a powerful argument that the problem resided with Henry. But Catherine bore the full weight of the blame. Her body and her dead children were used as evidence of divine displeasure.
Catherine died on January 7th, 1536, at Kimbolton Castle. She was 50 years old, worn down by decades of grief and stress. The official cause was recorded as “cancer of the heart.” Her embalmer reported that her heart was blackened and covered with an unusual growth—consistent with either cancer or, as some whispered, damage from toxic substances.
The ultimate irony is that her daughter Mary would eventually become Queen of England, despite everything Henry had done to prevent it. But Mary’s reign was haunted by the same shadows. Like her mother, she was consumed by the need to produce a Catholic heir. Like her mother, she experienced “phantom pregnancies” that ended in humiliation. Twice her abdomen swelled, and she reported feeling movement. Twice, no child materialized. History had repeated itself in the cruelest possible way.
The truth about Catherine’s children remains partially buried because the full evidence no longer exists. We are left with fragments, implications, and the testimonies of people who witnessed things they could not explain. Modern medical knowledge allows us to reconstruct what probably happened, but we cannot prove it definitively without examining remains that no institution will permit us to access.
Until the day those graves are opened, we are left with a story that is part history, part medicine, and part enduring cover-up—one that continues to shield the truth about what was happening in the royal bedchamber 500 years ago.
