Who Was Galileo Galilei?

1. Pisa, Padua and the making of a natural philosopher

Galileo Galilei was born on 15 February 1564 in Pisa, in the Grand Duchy of Tuscany, the eldest of seven children of Vincenzo Galilei, a musician and music theorist, and Giulia Ammannati. His father's work on music, which involved experiments with the pitch of strings, was an early influence: it showed the young Galileo that questions about nature could be answered by measurement rather than by authority. He was educated first at a monastery school and then at the University of Pisa, where he enrolled to study medicine at his father's wish and soon switched to mathematics and natural philosophy, the study of the physical world. He left Pisa without a degree, taught mathematics privately, and in 1589 was appointed to a chair of mathematics at Pisa, moving in 1592 to the University of Padua, in the Republic of Venice, where he would spend eighteen years, the most productive of his life.

At Padua, Galileo was a teacher, an inventor and an experimenter. He worked on the motion of falling bodies, on the pendulum, on the strength of materials, and on instruments such as the military compass, which he sold to students and soldiers. He also built a thermoscope, an early thermometer, and he corresponded with scholars across Europe. His teaching was famous: students came from many countries to hear him, and his lectures were known for their clarity and for their willingness to challenge the received wisdom of Aristotle, whose physics had dominated European universities for centuries. Aristotle had taught that heavy bodies fall faster than light ones, that the heavens are made of a perfect, unchanging substance, and that the Earth is at the centre of the universe. Galileo's experiments and observations would challenge each of these claims, and his method, the combination of careful observation, measurement and mathematical reasoning, would become the model for modern science.

The move to Florence in 1610, as court philosopher and mathematician to Cosimo II de' Medici, the Grand Duke of Tuscany, changed his life. It gave him a salary, a position and the patronage of one of the most powerful families in Italy, but it also took him from the relative freedom of the Venetian Republic, which was more tolerant of dissent, to a city where the Church's authority was closer and more immediate. The move was driven by ambition: Galileo wanted the leisure to write and the status of a court philosopher, and he believed that his telescopic discoveries had made him famous enough to be safe. The belief would prove mistaken, and the tension between his ambition and his safety is one of the threads that runs through the rest of his life.

2. The telescope and the discoveries of 1610

In the summer of 1609, Galileo heard reports of a Dutch invention, a spyglass that made distant objects appear near, and he built his own version, improving it until it magnified about twenty times. In the autumn of that year he turned it to the sky, and what he saw changed astronomy. The Moon, which Aristotle had taught was a perfect sphere, was covered in mountains and craters. The Milky Way, which had been thought to be a cloud, was made of countless individual stars. The planet Jupiter was accompanied by four small stars that moved around it, which Galileo called the Medicean Stars in honour of his patrons and which are now known as the Galilean moons: Io, Europa, Ganymede and Callisto. The discovery of moons orbiting a planet other than the Earth was a direct challenge to the idea that everything in the heavens orbited the Earth, and it was the first observational evidence that the Earth was not the unique centre of the universe.

He published these findings in March 1610 in a short book, Sidereus Nuncius, or The Starry Messenger, which became a sensation across Europe. The book was written in Latin, the language of scholars, and it was illustrated with his own drawings of the Moon's surface and of Jupiter's moons. It made him famous overnight, and it also made him enemies: some scholars refused to look through the telescope, arguing that the instrument deceived the eye, while others looked and claimed that what they saw was an artefact of the glass. Galileo responded by inviting sceptics to look for themselves, by repeating his observations, and by publishing his results quickly, a practice that would become standard in science. The speed of publication mattered: it established his priority, and it forced his critics to engage with evidence rather than with authority alone.

The discoveries continued. In 1610 and 1611 he observed the phases of Venus, which showed that Venus orbited the Sun rather than the Earth, a finding that was difficult to reconcile with the geocentric model of Ptolemy. He observed sunspots, dark patches on the Sun that moved across its face, which showed that the Sun itself changed, contradicting the idea of celestial perfection. He observed the rings of Saturn, which he could not resolve with his telescope and described as ears or handles, and he observed the changing appearance of the Moon and the planets over time. Each observation added to the case for a universe that was dynamic, imperfect and far larger than the ancient model allowed, and each made the question of the Earth's place in that universe more urgent.

3. Copernicus, the Church and the warning of 1616

Nicolaus Copernicus, a Polish astronomer, had published his heliocentric theory in 1543, in the year of his death, proposing that the Earth and the other planets orbit the Sun. The theory was mathematically elegant, but it lacked direct observational proof, and for decades it was treated by most astronomers as a useful hypothesis rather than as a description of physical reality. Galileo's telescopic discoveries changed that: they provided evidence that was difficult to explain on the geocentric model, and Galileo became the theory's most prominent advocate, arguing in his writings that the evidence pointed to a moving Earth and that the Bible, when it spoke of the Sun standing still, was describing appearances rather than physical truth. His argument about the interpretation of Scripture, made in his Letter to the Grand Duchess Christina in 1615, was that the Bible teaches how to go to heaven, not how the heavens go, a distinction that was theologically sophisticated and that many churchmen found threatening.

In 1616 the matter came to a head. A commission of theologians examined the Copernican propositions and declared that the idea that the Sun is at the centre of the universe and does not move was foolish and absurd in philosophy and formally heretical, and that the idea that the Earth moves was at least erroneous in faith. The Congregation of the Index issued a decree suspending Copernicus's book until it was corrected, and Cardinal Robert Bellarmine, one of the most respected theologians of the Church, met with Galileo and warned him not to hold or defend the Copernican theory. The exact terms of that warning became a central issue in Galileo's later trial: Bellarmine's own record said that Galileo was warned not to hold or defend the theory, while a second, unsigned record in the file said that he had been ordered not to teach it in any way whatsoever. The difference between the two formulations, whether Galileo was forbidden to discuss the theory at all or only to present it as established truth, would be decisive in 1633.

Galileo obeyed the warning for a time, turning to other work, but the election in 1623 of Cardinal Maffeo Barberini as Pope Urban VIII gave him hope. Barberini was a cultured Florentine who had admired Galileo and had written a poem in his honour, and Galileo believed that the new pope would allow a fair discussion of Copernicanism, provided that it was presented as a hypothesis and that the power of God was not limited by human argument. He spent years writing a book that would present the two systems, the geocentric system of Ptolemy and the heliocentric system of Copernicus, in dialogue form, and he obtained permission to publish it, with the condition that it treat the Copernican theory as a hypothesis and include the pope's own argument at the end. The book, when it appeared, did not do what the permission required, and the consequences were severe.

4. The Dialogue and the trial of 1633

The book, Dialogue Concerning the Two Chief World Systems, was published in Florence in February 1632. It was written in Italian rather than Latin, so that educated readers who were not scholars could read it, and it was structured as a conversation over four days between three characters: Salviati, who argued for Copernicus; Sagredo, an intelligent layman who asked questions; and Simplicio, who defended Aristotle and Ptolemy. The choice of names was unfortunate: Simplicio, whose name suggested simplicity, was given the pope's own argument about divine omnipotence to defend, and he was made to look foolish. Whether Galileo intended the insult or not, Urban VIII took it as one, and the political context made the matter worse: the pope was under pressure from his enemies, the Thirty Years' War was raging in Europe, and the publication of a book that seemed to defy the Church's authority was seen as a challenge that could not be ignored.

Galileo was summoned to Rome. He arrived in February 1633, ill and elderly, and was examined by the Inquisition over the following months. The tribunal produced the unsigned record of 1616, which said that he had been ordered not to teach Copernicanism in any way whatsoever, and argued that the Dialogue violated that order. Galileo maintained that the book did not defend heliocentrism but merely presented arguments on both sides, and that he had acted in good faith under the permission he had been given. The tribunal rejected this defence. On 22 June 1633, in the church of Santa Maria sopra Minerva in Rome, Galileo was found vehemently suspected of heresy, required to abjure the Copernican theory, and sentenced to formal imprisonment at the pleasure of the Inquisition, a sentence that was commuted almost immediately to house arrest. The Dialogue was placed on the Index of Prohibited Books, where it remained until 1835.

The trial has been debated ever since, and scholars disagree about how to interpret it. Some have argued that it was primarily a matter of theology, a defence of the authority of Scripture against a scientific claim that seemed to contradict it. Others have argued that it was primarily political, a demonstration of papal authority at a moment when the pope felt threatened, and that the theological issues were secondary. Still others have pointed to Galileo's own conduct, his provocative tone, his willingness to present the Copernican theory as more certain than the evidence allowed, and his failure to appreciate the political constraints under which the pope operated. The most careful modern scholarship, exemplified by the work of historians such as Maurice Finocchiaro, treats the trial as a combination of all three: a genuine theological disagreement, a political crisis, and a personal conflict, in which each side misunderstood the other. What is not in doubt is the outcome: Galileo was silenced, his book was banned, and the Church's authority over the discussion of cosmology was asserted in a way that would shape Italian science for generations.

5. House arrest, blindness and the Two New Sciences

Galileo spent the remainder of his life under house arrest, first in Rome, then in Siena with the archbishop, and finally at his villa at Arcetri, near Florence, where he lived from late 1633 until his death. The conditions were less harsh than a prison cell, but they were real: he was forbidden to publish, to teach, and to receive visitors freely, and his movements were restricted. He was also required to recite the seven penitential psalms once a week for three years. Despite these restrictions, he continued to work, corresponding with scholars across Europe, receiving visitors who came to see him, and writing the book that would become his most important contribution to physics. His eyesight, which had been failing for years, deteriorated, and by 1638 he was effectively blind, a condition he bore with a mixture of resignation and frustration, dictating his work to his son and to his students.

The book he wrote in these years, Discourses and Mathematical Demonstrations Relating to Two New Sciences, was published in Leiden in the Netherlands in 1638, beyond the reach of the Inquisition, and it is now regarded as his masterpiece. It returned to the questions of motion that he had studied since his youth in Pisa: how bodies fall, how projectiles move, how the strength of materials can be calculated. In it he set out the law of falling bodies, that in the absence of air resistance all bodies fall at the same rate, and the principle of inertia, that a body in motion will continue in motion unless acted upon by a force, ideas that would be taken up by Isaac Newton and built into the laws of motion that still bear Newton's name. The book was written as a dialogue, like the Dialogue of 1632, but its subject was physics rather than cosmology, and it was therefore less dangerous to the Church. It was, in effect, the founding text of the modern science of mechanics.

Galileo died on 8 January 1642 at Arcetri, at the age of seventy-seven, and was buried in a side chapel of the church of Santa Croce in Florence, rather than in the main body of the church as his admirers had wished, because the Church would not allow a full honour for a man condemned by the Inquisition. His remains were later moved to a tomb in the main church, and his reputation, which had been damaged by the trial, began to recover in the decades after his death, as the heliocentric theory became accepted and as the scientific revolution he had helped to start transformed European thought. The house arrest had not stopped his work; it had, in a sense, concentrated it, forcing him to turn from the heavens to the more fundamental questions of motion that would prove his most lasting contribution.

6. The legend, the evidence and what scholars now say

Two legends about Galileo are so well known that they are often mistaken for fact, and both deserve to be examined. The first is that he dropped two balls of different weights from the Leaning Tower of Pisa to prove that they fall at the same rate. There is no contemporary evidence that he performed this experiment, and the story comes from a biography written by his student Vincenzo Viviani decades after his death. Galileo did argue, on the basis of thought experiments and of experiments with inclined planes, that bodies fall at the same rate, but the tower story is almost certainly a later invention. The second legend is that, after abjuring the Copernican theory in 1633, he muttered Eppur si muove, and yet it moves, under his breath. There is no contemporary evidence for this either, and the phrase first appears in accounts written more than a century later. Both legends are appealing because they present Galileo as a defiant hero, but the historical Galileo was more complicated: a man who abjured because he had no choice, and who continued his work in the only way available to him.

The scholarly debate about Galileo has also changed over time. Earlier histories presented him as a martyr of science, persecuted by a Church that was hostile to reason, and the trial as a simple conflict between truth and dogma. More recent scholarship has emphasised the complexity of the affair: that many churchmen were themselves interested in astronomy, that the Church's position in 1616 was based on the state of the evidence as it then stood, since the Copernican theory lacked the proof that would later come from stellar parallax and from Newton's physics, and that Galileo's own presentation of the theory was more certain than the evidence warranted. This does not excuse the trial, which was unjust by any modern standard, but it does make it more intelligible as a historical event rather than as a morality tale. The Catholic Church itself acknowledged the error in 1992, when Pope John Paul II, speaking to the Pontifical Academy of Sciences, said that the theologians who condemned Galileo had erred and spoke of a tragic mutual incomprehension.

The question of what Galileo proved, and what he did not, is also worth stating clearly. He did not prove that the Earth moves around the Sun: the proof of stellar parallax, the apparent shift in the position of nearby stars as the Earth moves, was not observed until the nineteenth century, and the full physical explanation of the Earth's motion required Newton's theory of gravitation. What Galileo did was to provide strong evidence that the ancient geocentric model was wrong, that the heavens were not perfect and unchanging, and that the telescope had opened a new world of observation that could not be ignored. His contribution was not a single proof but a method: the combination of observation, experiment and mathematical reasoning that would become the foundation of modern science. That is why he is called the father of modern science, not because he settled the question of the Earth's motion, but because he showed how such questions should be answered.

7. Legacy: the father of modern science

Galileo's legacy is visible in every laboratory and observatory in the world, because the method he practised is the method that science still uses. The idea that a theory should be tested by observation, that an experiment should be repeatable, that a result should be published so that others can check it, and that authority, whether Aristotle's or the Church's, is not a substitute for evidence, all owe something to his example. His influence on later scientists was direct: Isaac Newton, who was born in the year Galileo died, built his laws of motion on Galileo's work on falling bodies and on inertia, and the history of physics from Newton to Einstein can be traced back to the questions Galileo asked in Padua and at Arcetri. His influence on astronomy was equally direct: the moons of Jupiter, the phases of Venus and the mountains of the Moon are still observed by amateur astronomers with telescopes not very different in principle from the one he built in 1609.

His legacy is also a cautionary tale about the relationship between science and authority. The trial of 1633 is often cited as a warning about what happens when institutions try to settle scientific questions by decree, and the fact that the Church took until 1992 to acknowledge the error is a reminder of how slowly institutions correct themselves. But the trial is also a reminder that science does not advance by heroism alone: it advances by the slow accumulation of evidence, by the willingness to publish and to be corrected, and by the institutions, universities, academies and journals, that Galileo helped to create. The most useful lesson of his life may be that the conflict between science and authority is not inevitable, but that it becomes likely when either side claims a certainty that the evidence does not support.

For readers who want to understand the scientific revolution, Galileo is the best place to start, because his life contains the whole story in miniature: the challenge to ancient authority, the new instrument that opened a new world, the publication that made the discovery public, the conflict with an institution that felt threatened, and the final work, written in confinement, that proved more lasting than the controversy. He was not a saint, and he was not a simple hero, but he was a man who looked through a telescope, saw what no one had seen before, and refused to pretend that he had not seen it. That is why, almost four centuries after his death, his name is still the first that comes to mind when we think of the birth of modern science.
