All true, and all a little hard to believe — collisions of time, faith, and empire across the Christian centuries.

Surprising life

Before he was pope, he wrote a bestselling erotic novel

In 1444, years before he was elected Pope Pius II, the humanist Aeneas Silvius Piccolomini wrote The Tale of Two Lovers (Historia de duobus amantibus) — an erotic tale of the affair between a married woman and a courtier, told largely through their exchanged love letters. It became one of the runaway bestsellers of the 15th century and is often cited as one of the earliest novels-in-letters in European literature. Later, as pope, he tried to disown the racy writings of his youth.

Surprising life

His own family kidnapped him to stop him becoming a friar

When the young nobleman Thomas Aquinas joined the new Dominican order in 1244, his aristocratic family was so appalled that his brothers seized him on the road and held him under house arrest in the family castles for about a year. According to his early biographers they even sent a woman into his room to break his resolve, and he drove her out with a burning stick from the fire. Released in 1245, he went straight back to the Dominicans — and became the most influential theologian of the Middle Ages.

A third-century scholar built a six-column Bible by hand

Around 235–245 CE, the Alexandrian scholar Origen laid out the Old Testament in six parallel columns — the Hebrew text, that same text spelled in Greek letters, and four different Greek translations side by side — so readers could compare them line for line. The result, called the Hexapla, was so enormous, by some estimates several thousand pages across dozens of volumes, that it was likely never fully copied; the original was eventually lost.

The Italian priest an emperor let bury in Beijing

Matteo Ricci sailed from Lisbon in 1578, reached China in 1582, and spent nearly twenty years working his way inland until he entered Beijing in 1601, where he presented the Wanli emperor with chiming clocks and a Chinese-language world map. Ming law required foreigners who died in China to be buried far away in Macau — but when Ricci died in Beijing in 1610, the emperor granted him a burial plot in the capital, an honor never before given to a European.

Two of the great Church Fathers were brothers from a family of saints

Basil the Great and Gregory of Nyssa — two of the three Cappadocian Fathers whose writing shaped the doctrine of the Trinity — were biological brothers in a single 4th-century household. Their older sister Macrina the Younger and another brother, Peter of Sebaste, are also venerated as saints, and their parents and grandmother are honored too. One family produced a remarkable cluster of the early Church's saints.

The philosopher who wrote his masterpiece on death row

Boethius was one of the highest officials of Ostrogothic Italy — a former Roman consul serving as master of offices under King Theodoric — when he was arrested on charges of treason around 523 CE. Imprisoned and awaiting execution, he composed The Consolation of Philosophy, which became one of the most widely read and copied books of the entire Middle Ages.

A cannonball to the leg launched the Jesuits

Ignatius of Loyola was a professional Basque soldier when a cannonball shattered his leg at the defense of Pamplona in 1521. Bedridden for months, he read the devotional books at hand and resolved to leave soldiering for religious life. Nineteen years later, in 1540, the pope formally approved the order he founded — the Society of Jesus.

A churchman argued the Earth moves — a century before Copernicus

In his 1440 work On Learned Ignorance, Nicholas of Cusa — later made a cardinal — argued that the universe has no fixed center, that the Earth is not at rest, and that the stars might be distant suns like our own. He wrote it more than a century before Copernicus published his heliocentric model in 1543.

From unbaptized governor to bishop in about eight days

When the see of Milan fell vacant in 374 CE, the Roman provincial governor Ambrose stepped in to calm a disputed election — and the crowd instead acclaimed him bishop, though he was still an unbaptized catechumen. He was baptized and, by tradition about a week later, consecrated bishop of Milan.

He wrote celebrated poetry while imprisoned by his own order

In 1577 the Spanish friar John of the Cross was seized by fellow Carmelites who opposed the reform he supported, taken to Toledo, and held for months in a cramped cell. During and after that confinement he composed some of the most admired verse in the Spanish language — including much of the Spiritual Canticle — before escaping in 1578.

The pope who rode out to meet Attila the Hun

In 452 CE, as Attila and his Huns pushed into northern Italy, Pope Leo the Great travelled north and met Attila near the river Mincio, by Mantua. Attila soon withdrew from Italy — ancient and later writers gave differing explanations for why. Three years later Leo led a similar embassy to the Vandal king during the sack of Rome.

Augustine died with an enemy army at the gates

Augustine of Hippo spent his final months in his North African city of Hippo Regius as the Vandals besieged it; he died there in August 430, about three months into the siege. His great work The City of God had been begun years earlier, in response to the sack of Rome in 410.

A peace treatise written in the shadow of a fallen city

Nicholas of Cusa had travelled to Constantinople on a Church embassy in the 1430s.

The mathematician who was pope at the year 1000

Gerbert of Aurillac — who studied mathematics and astronomy in Catalonia — became Pope Sylvester II and held the office from 999 to 1003, sitting as bishop of Rome across the turn of the year 1000.

The cardinal, the astronomer, and the playwright — all alive in 1616

In February 1616, Cardinal Robert Bellarmine delivered the Church's formal admonition to Galileo not to hold or defend the idea that the Earth moves. That same year, William Shakespeare died in the spring (23 April on England's old calendar, 3 May on the Gregorian calendar Rome used) — so in the opening weeks of 1616 the cardinal, the astronomer, and the playwright were all living men at once.

Old enough to watch Columbus come home

Bartolomé de las Casas, who would later become a prominent defender of Indigenous peoples, was a boy of about eight in Seville in the spring of 1493 when Christopher Columbus paraded through the city on his return from the first Atlantic crossing.

The monk who taught Europe to count the years

The AD system of numbering years was devised by Dionysius Exiguus around 525 CE, but it was Bede the Venerable who spread it. In works completed in 725 and 731 CE he popularized counting years from a date traditionally assigned to the birth of Jesus — and he was among the first writers to reckon years backward before that point as well.

For 600 years, he was the only Aristotle the West had

Boethius, the Roman official executed around 524 CE, translated and explained Aristotle's works on logic into Latin. Because the rest of Aristotle was lost to the West or not yet translated, his renderings were essentially the only Aristotle available in Western Europe for roughly six centuries — until a wave of new translations arrived in the late 1100s.

The pope who deleted ten days from the calendar

In 1582 Pope Gregory XIII reformed the calendar to correct the drift the old Julian system had let build up in the seasons. Under the new Gregorian calendar, Thursday 4 October 1582 was followed directly by Friday 15 October 1582 — so ten dates, the 5th through the 14th, simply never existed. That calendar is the civil standard used worldwide today.

The book often called the West's first autobiography

Around 397–400 CE, Augustine of Hippo wrote the Confessions, an intimate first-person account of his own life, doubts, and change of heart. It is frequently described as the first autobiography in the Western literary tradition, and has been read continuously for over 1,600 years.

The executed translator whose words still fill the English Bible

William Tyndale printed the first English New Testament translated directly from the Greek in 1526, and was executed for heresy in 1536. His phrasing endured: much of the wording of the 1611 King James Bible follows Tyndale — one common estimate puts its New Testament at roughly 83% his — and everyday English expressions such as “let there be light,” “the powers that be,” and “a law unto themselves” trace to his translation.

The court scholar behind our lowercase letters

Alcuin of York led the palace school of Charlemagne and helped drive a reform of handwriting.
