How to Make Boys “Sing Like Angels”.
How many were abused like this? The full 340-year history of the church requesting these abused boys produces an estimated 700,000–800,000 boys, (almost a million) with roughly 600,000+ harmed without benefit of a career in singing. See the math below.
When Girls Are Forbidden to Sing: The Making of Castrati
By Victoria Siegel — Rational Body Publishing
There is a Saturday Night Live sketch where Ariana Grande plays a castrato. The bit involves someone casually describing the procedure as just tweeeesting the balls. The audience laughs. Grande's character sings in an impossibly high register while looking mildly inconvenienced.
It is funny. It is also one of the few times mainstream culture has mentioned this practice at all in the last century, which is itself a kind of answer to how thoroughly we have buried what happened.
Because what happened was not a twisting.
What happened was that the Catholic Church barred women from singing in sacred spaces — because their voices were too beautiful, too powerful, too distracting, too much — and then, in need of high voices for increasingly elaborate sacred music, turned to a solution: boys. Poor boys. Boys as young as seven years old, taken to surgeons, and castrated before puberty so their voices would not change.
And then the Church — the same Church that officially condemned the practice — employed them, celebrated them, and kept them in the Vatican choir until 1903.
The last famous castrato died in 1922. An Italian source title cited in biographical material calls him “L’angelo di Roma” — “the Angel of Rome.” He sang in the Sistine Chapel choir, recorded in 1902 and 1904, remained officially in the choir until 1913, and died in 1922.
This is not ancient history. This is within living memory of people alive today.
Pope Clement VIII is quoted in a medical-history account as saying the creation/use of castrati for church choirs was “ad honorem Dei” — “to the honor of God.” The mutilated boy’s voice was justified as sacred service.
They were treated as producing one of the most beautiful, sacred, and otherworldly sounds in Christendom — a beauty made possible by a violence the Church preferred not to name.
It all started with forbidding women’s voices, since they were treated as dangerously powerful.
Why Women Were Removed
The story begins, as so many of these stories do, with a misread line of scripture.
First Corinthians 14:34: "Women should keep silence in the churches."
Paul wrote that line in a specific context — scholars debate whether it referred to disruptive questioning during services, or to a particular congregational dispute in Corinth, or to women speaking in tongues. What it almost certainly was not was a blanket prohibition on female participation in sacred music for all time across all cultures.
But that is how it was used.
Over centuries, this passage and related texts were weaponized into a systematic exclusion of women's voices from church settings. In practice, the exclusion varied by time and place — women sang in convents, in some folk traditions, in certain regional exceptions. But in the formal sacred music of Rome, of the Sistine Chapel, of the great cathedral choirs, women were pushed out or never allowed in.
This is the same pattern I have traced in my book Playing With Fire: the frame drum held by women in every ancient image, the suppression timeline from 363 AD through the 6th century, the replacement of communal rhythm with delivered grandeur. Sacred music became something produced by men, for men, under male authority, in service of male institutional power.
But sacred music still needed high voices.
The human ear, and the human soul, wants to go up. High voices pierce something. They open something. The soprano line in sacred polyphony is not decorative — it carries. It soars. Medieval and Renaissance composers wrote music that required those upper registers, and as the music became more complex and more demanding, the need for powerful, trained, reliable high voices became acute.
Women could provide those voices. Women did provide those voices, in settings where they were permitted.
But the official Church said no. And then the official Church said: find another way.
The way they found was the knife.
The System
Boys were castrated before puberty — typically somewhere between the ages of seven and twelve, with medical-historical sources emphasizing seven to nine as the most common range for those intended for the finest musical outcomes. The goal was to intervene before the hormonal surge of testosterone that would transform the larynx, thicken the vocal cords, lower the voice, and produce the irreversible changes of male adolescence.
The operation was performed by surgeons, but it was almost never officially recorded as what it was. Families and doctors used euphemisms: the boy had suffered an accident. A fall. A horse kick. A pig bite. He had needed treatment for a hernia, and something had unfortunately gone wrong. The law was often formally against the practice. The Church condemned it in theory. Popes issued statements against castration.
And yet the Sistine Chapel had its first recorded castrato in 1562. Pope Sixtus V officially authorized recruitment of castrati into the papal choir in 1589. They sang at St. Peter's Basilica and throughout the Roman sacred music world for the next three centuries. The Vatican kept them until Pope Pius X finally ended their use in 1903 — three hundred and fourteen years after Sixtus authorized their employment.
This is what institutional evasion looks like at scale: condemn the means, celebrate the result, and let families and surgeons absorb the moral weight of the transaction.
The system worked because it distributed complicity across many hands.
Parents could tell themselves they were rescuing a son from poverty. A beautiful boy voice in a poor family could look like a lottery ticket — if the operation succeeded, if the voice developed properly, if the boy survived the training and found a placement, he might lift the whole family. Surgeons could take payment. Conservatories could accept students. Church officials could hire trained singers without asking too carefully where they came from. Audiences could weep at the beauty.
Nobody had to hold the knife except the surgeon.
What the Knife Actually Did
The popular version — just tweeesting the balls — gets the site right but misses the reality. Surgical castration before puberty meant the removal or destruction of the testicles, eliminating the primary source of testosterone production. Chemical castration and other methods were not typically used in this historical period; surgical removal was the standard. Some accounts describe tying off the spermatic cord; others describe direct removal. Boys were sometimes given opium or alcohol before the procedure. Many died from infection. The sterile operating conditions of modern medicine did not exist.
Those who survived faced a body permanently altered by the absence of testosterone during development.
Testosterone does not only change the voice. It regulates skeletal maturation. It drives the closure of growth plates — the areas of cartilage near the ends of long bones that allow them to lengthen during childhood. Without normal testosterone levels, the growth plates of castrated boys stayed open longer. Their bones kept growing past the point where they would normally have stopped.
The result was a body that was strange by the standards of the time: often unusually tall, with long limbs, a large rib cage, a broad chest. The chest cavity and lungs grew to full adult size — or beyond — while the larynx did not. That combination is what gave the great castrati their famous power: the high, clear register of a child, driven by the lung capacity and trained breath control of a large adult.
Musically: extraordinary.
Physically: the documented consequences were significant.
Medical and skeletal studies of eunuchs and castrated individuals describe several documented effects of prepubertal castration:
Delayed epiphyseal closure — bones continue growing longer than normal
Altered skeletal proportions — unusually long limbs relative to the trunk
Reduced bone density — testosterone normally promotes bone mineralization; without it, bones become less dense
Early onset osteoporosis — fragile bones, spinal compression, fractures in later life
Kyphosis — spinal curvature, particularly in the upper back, as the spine weakens
Gynecomastia — development of breast tissue, as estrogen activity is no longer counterbalanced by testosterone
Reduced or absent prostate development
Complete infertility
Altered fat distribution — more typically female fat distribution patterns
Modern examination of the remains of Farinelli — the most famous castrato of the eighteenth century — found skeletal abnormalities consistent with the long-term effects of prepubertal castration. He was not alone. Studies of other eunuch remains across different historical periods and cultures show the same constellation of effects.
The body the Church prized was a body that had been broken in specific, documented ways to produce a specific, marketable sound.
The Fame and the Failure
At the peak of the castrato phenomenon — roughly the seventeenth and eighteenth centuries — historians and medical writers estimate that as many as four thousand boys per year were castrated in Italy. Some older medical-historical accounts give a range of four thousand to five thousand annually. These numbers cannot be verified precisely because the operation was disguised, records were incomplete, and the practice was geographically distributed across a country with no unified record-keeping. But the order of magnitude is supported by the scale of the institutional demand: dozens of conservatories, hundreds of church choirs, a thriving opera circuit, and wealthy patrons all wanted these singers.
Most of the boys came from poor families in Naples and other parts of southern Italy, where poverty was severe and the church and opera houses represented real routes to advancement.
The odds were brutal.
A tiny minority became what we might today call global superstars. Farinelli (Carlo Broschi, 1705–1782) sang for royalty across Europe, spent decades as a confidant of the King of Spain, was reportedly paid the equivalent of a modern fortune, and was treated as something close to miraculous. Senesino, Caffarelli, Crescentini — a handful of others — became the first true international music celebrities, the ancestors of every rock star and pop idol who came after them.
Below that tier, perhaps ten percent found sustainable careers as professional singers in churches, cathedral choirs, chapels, conservatories, minor opera circuits, or private noble households. They were not famous. They were employed. That was already more than most poor boys of the era could expect.
The remaining majority — the overwhelming portion of the boys who went under the knife — received none of the promised reward. Some died from the operation itself. Some survived the surgery but never developed the voice that was anticipated. A boy castrated at eight would not know until his mid-teens whether the gamble had paid off, and by then the decision was irreversible. Some emerged from training unable to compete for professional positions. Some found their bodies too altered, too visibly different, too marked. Infertility was universal. Social belonging was complicated or foreclosed.
They could not father children. They were often barred or strongly discouraged from marriage. Their bodies did not fit the gender categories of the world that had made them.
The Church and society had made them strange, and then punished them for the strangeness.
The Worship and the Mockery
The most successful castrati were treated with a kind of worship that was also always, underneath it, a kind of freak show.
Audiences were said to shout "Evviva il coltello!" — "Long live the knife!" — at performances of the great virtuosos. Whether this was literal or apocryphal, it captures something real: Europe did not simply tolerate the wound. It celebrated the wound. It paid to see the wound perform. It wept at the beauty the wound produced.
And then it went home and tried not to think too hard about where the beauty came from.
The castrati were praised as angels. They were also sexualized, feminized, exoticized, and insulted. Satirists mocked their bodies. Aristocrats treated them as ornaments. Some were involved in romantic and sexual relationships with both women and men — their social position was ambiguous enough that normal rules sometimes did not apply. Some found this freedom, such as it was, meaningful. Most did not choose any of it freely.
Farinelli was rich, admired, and connected to courts across Europe. He was also a man who could not father children, who had been altered before he could consent, who spent decades serving at the pleasure of a foreign king, and who retired to a villa in Bologna where he collected keyboard instruments and reportedly grew melancholy in his final years.
The winner's life was still a life shaped entirely by a decision made when he was a child.
How It Ended — And How Long It Took
By the late eighteenth century, taste was shifting. Enlightenment thinkers found the castrato increasingly grotesque. New ideals of heroic masculinity on stage favored tenors and baritones. Women were gradually allowed back into public musical performance in secular settings. The great age of castrati in opera faded.
But the Church was slower.
The Church is always slower.
The Vatican's Sistine Chapel kept castrati in the choir long after opera had moved on. This is perhaps the most damning fact in the entire history: the institution that created the demand was the last to relinquish it.
Alessandro Moreschi was born in 1858. He was castrated as a child — the exact age and circumstances are not fully documented. He trained, developed his voice, and joined the Sistine Chapel choir, eventually becoming its director. He sang at the Vatican for decades, performing at the funerals of popes and for heads of state.
In 1902 and 1904, he made recordings. They are the only known recordings of a castrato voice in history.
Listen to them and the experience is difficult to name. The recording technology was primitive — early cylinder recordings, thin and crackled. Moreschi was older by then, well past his prime. The sound is not the superhuman vocal spectacle that eighteenth-century audiences described. It is high, strained, devotional, human. It sounds like a man carrying something for a very long time.
Pope Pius X ended the use of castrati in the Sistine Chapel in 1903. Moreschi retired in 1913. He died in 1922.
Nineteen twenty-two.
The year the BBC was founded. The year T.S. Eliot published The Waste Land. The year Mussolini came to power in Italy. The year insulin was first used to treat a human patient.
A man whose testicles had been removed as a child for sacred music lived and died in the modern world.
This is not medieval history.
The Argument I Am Making
The castrati are almost always presented as a music history curiosity: strange, baroque, a little titillating, ultimately harmless because it was all so long ago.
I want to argue something different.
The castrati are what happens when you remove women from a position they legitimately hold — here, the position of singer, musician, voice — and then scramble to replace what you destroyed.
Women's voices were treated as dangerous because they were powerful. They could move congregations. They could command attention. They could rival the emotional authority of the priest. In a patriarchal religious order, that kind of power in a female body was not neutral. So the Church removed it.
And then it needed what it had removed. It needed the high voice. It needed the beauty. It just needed it without the woman attached.
So it found a way to have women's voices without women. It altered boys' bodies until those bodies could produce a sound adjacent to what female voices produced naturally. It trained those bodies for a decade. It employed those bodies. It celebrated those bodies.
And then it looked away from what it had taken.
This is the pattern I trace throughout Playing With Fire: the frame drum removed from women's hands, replaced by the pipe organ played from above. The feminine spirit in the Trinity grammatically erased through translation. The women's leadership roles in early Christianity stripped out by councils and canon. The sacred associated with the feminine — voice, body, rhythm, birth, cycle, nature — pushed out and replaced by something male, vertical, institutional, controlled.
The castrati are one chapter in that story. A particularly horrifying chapter, because here the violence against the female was so complete that when it could not be sustained — when you actually need a high voice and you have banned the people who have high voices — the institution turned to children's bodies as the next best substitute.
Women's voices were too powerful to remain.
Boys' bodies were disposable enough to use instead.
That is the sentence the music history books soften. I am not going to soften it.
The Last Recording
You can find Moreschi's recordings online. They have been digitized and uploaded. They are public. Anyone can listen.
I recommend listening before reading any description of what you are about to hear. Let the sound arrive without context first.
Then let the context arrive.
Behind the crackle of an early cylinder recording is a man who was a boy when someone held a knife over him. Who trained for a decade to produce a sound the world wanted. Who sang at popes' funerals. Who retired in 1913 and spent nine years living out the rest of a life he never chose.
His recordings are sometimes called a curiosity. A footnote. An artifact.
They are evidence.
Evidence of what the institution wanted. Evidence of what the institution took. Evidence that the beauty it prized was not separate from the wound it caused — that the beauty was the wound, dressed in robes, placed in a choir loft, called sacred, and applauded until it died.
No voice is angelic enough to excuse what was taken.
And the girls who were silenced so this could happen — the women whose voices were called dangerous, distracting, improper, too lovely, too much — they never got to make a recording.
We will never know what we lost when we lost them.
Data Summary
Practice: Castration before puberty to preserve a high male singing voice for sacred music and opera.
Primary justification: Women barred or discouraged from sacred singing by misapplication of Pauline scripture; castrati supplied upper vocal lines without female singers.
Common age at castration: Approximately 7–12 years old. Medical-historical sources often emphasize 7–9 as the target range for optimal vocal results.
Method: Surgical removal or destruction of the testicles. Chemical castration was not used in this period. Operations were dangerous; boys died from infection and surgical complications.
Peak period: Late sixteenth century through the eighteenth century in Italy; some continuation in sacred music through the nineteenth century.
Estimated scale at peak: Historians and medical writers commonly cite approximately 4,000 boys castrated annually in Italy at the practice's height; older medical-historical accounts give a range of 4,000–5,000. These figures are estimates, not verified census data, but are supported by the documented scale of institutional demand.
Career outcomes: Only a tiny minority became international stars. A larger group found modest professional work in churches, chapels, or minor musical circuits. The majority did not achieve the reward promised and faced lifelong consequences. The popular shorthand of 1% famous / 10% modest career / 90% failed or harmed reflects historian consensus about the shape of outcomes, not a verified statistical breakdown.
Physical consequences: Infertility. Altered skeletal growth from delayed epiphyseal closure. Unusually long limbs. Expanded rib cage. Reduced bone density. Early osteoporosis. Kyphosis (spinal curvature). Gynecomastia (breast tissue development). Absent or reduced prostate development. Altered fat distribution. Effects more severe when castration occurred before puberty.
Church role: Sistine Chapel admitted first recorded castrato in 1562. Pope Sixtus V authorized recruitment of castrati into the papal choir in 1589. Castration was formally condemned but the Church continued employing, training, and celebrating castrati.
Vatican end date: Pope Pius X ended the use of castrati in the Sistine Chapel in 1903.
Last famous Vatican castrato: Alessandro Moreschi, born 1858. Made the only known recordings of a castrato voice in 1902 and 1904. Retired 1913. Died 1922.

Appendix: The Scale — Attempting the Math
What follows is an attempt to quantify the human cost. The inputs are estimates and historical ranges, not verified census data. The method is transparent so the reasoning can be challenged.
The documented range: Historians commonly cite approximately 4,000 boys castrated annually in Italy at the practice's height. Some older medical-historical accounts give 4,000–5,000. I will use 4,000 as the working annual figure for peak decades, and 2,000 as the working figure for the earlier and later decades of the practice.
The timeline: The castrati tradition ran from approximately the 1560s to 1903 — roughly 340 years. The practice was not uniform across that period:
Early period (~1560–1650): growing, perhaps 500–1,000 boys annually
Peak period (~1650–1800): approximately 3,000–5,000 boys annually, centered around 4,000
Declining period (~1800–1903): falling, perhaps 500–2,000 boys annually
A rough calculation by period:
Period Years Estimated annual castrations Period total 1560–1650 90 ~750 average ~67,500 1650–1800 150 ~4,000 average ~600,000 1800–1903 103 ~1,000 average ~103,000 Total 343 years ~770,000
This produces an order-of-magnitude estimate of roughly 700,000 to 800,000 boys castrated across the full history of the practice in Italy. This is Italy only — similar but smaller practices existed in Spain and other Catholic European countries.
The 100,000 in a single year figure: At the peak, if estimates of 4,000–5,000 per year are correct, a single decade at peak would have seen 40,000–50,000 boys. One hundred thousand would represent approximately 20–25 years at the highest estimated rate. That figure is therefore plausible as a multi-decade cumulative total during the peak, not a single-year figure. A single peak year would be 4,000–5,000, not 100,000.
Outcomes applied to the total:
Using the historian consensus shape — tiny minority became stars, modest minority achieved careers, the large majority bore costs without proportionate reward:
~1% who achieved significant fame or wealth: approximately 7,000–8,000 boys
~10% who achieved modest professional careers: approximately 70,000–80,000 boys
~89% who were harmed without achieving the promised benefit: approximately 620,000–690,000 boys
The majority of boys who went through this procedure received none of the benefit and all of the consequences: infertility, altered bodies, skeletal damage, and social marginalization — in service of a sound the Church wanted but refused to allow women to provide.
The bottom line: The total number of boys whose bodies were permanently altered for sacred and operatic music across the full history of the European castrato tradition is estimated in the range of 700,000 to 800,000, concentrated heavily in Italy, with the peak of harm occurring between 1650 and 1800. Of those, the overwhelming majority — perhaps 600,000 or more — bore permanent consequences without the professional reward that justified the gamble in their families' minds.
These are estimates, not census figures. The operation was hidden, euphemized, and under-recorded. The real total may be higher. It cannot be lower than the documented institutional demand requires.
