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.

How we know

Boethius c. 480–524 CE; Roman consul in 510, then magister officiorum under Theodoric; arrested for treason c. 523, wrote The Consolation of Philosophy in prison, executed c. 524.

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.

How we know

Ignatius 1491–1556; wounded at Pamplona on 20 May 1521; the Society of Jesus was approved by Pope Paul III in 1540.

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.

How we know

Nicholas of Cusa 1401–1464; De docta ignorantia (1440), Book II; Copernicus's De revolutionibus, 1543 — 103 years later.

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.

How we know

Ambrose of Milan c. 339–397; governor of Aemilia-Liguria, acclaimed and consecrated bishop of Milan on 7 December 374 while still unbaptized (baptized about eight days earlier).

Surprising life

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.

How we know

John of the Cross 1542–1591; seized December 1577, imprisoned in Toledo, composed much of the Spiritual Canticle there, escaped August 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.

How we know

Pope Leo I (bishop of Rome 440–461) met Attila near the Mincio in 452 CE; Attila then withdrew from Italy. Leo also interceded with the Vandal king Genseric during the sack of Rome in 455.

He learned Rome had fallen from his monastery in Bethlehem

When Alaric and the Visigoths sacked Rome in 410 CE, Jerome was some 1,400 miles away in his monastery at Bethlehem, at work translating and writing. Recording his shock, he wrote that “the city which had taken the whole world was itself taken.”

How we know

Sack of Rome by Alaric, August 410 CE; Jerome (c. 347–420) lived at his Bethlehem monastery from c. 386; the line is from the preface to his Commentary on Ezekiel.

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.

How we know

Augustine 354–430, died 28 August 430 during the Vandal siege of Hippo Regius; The City of God begun c. 413 after the sack of Rome (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. When the city fell to the Ottomans in 1453, he responded not with a call to arms but by writing On the Peace of Faith within months — a work imagining a peaceful conference among representatives of many nations and religions.

How we know

Nicholas of Cusa 1401–1464; embassy to Constantinople 1437–38; Constantinople fell in May 1453; De pace fidei composed later that year.

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. He is credited with reintroducing the abacus and the armillary sphere to Latin Europe and with promoting Hindu-Arabic numerals in the Christian West.

The pope who placed the crown on Charlemagne

Pope Leo III crowned Charlemagne “Emperor of the Romans” in St. Peter's Basilica on Christmas Day, 25 December 800 — an act Western tradition marks as the rebirth of a Roman imperial title in the West.

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 April — so in the opening weeks of 1616 the cardinal, the astronomer, and the playwright were all living men at once.

How we know

Bellarmine 1542–1621 admonished Galileo (1564–1642) on 26 February 1616; Shakespeare (1564–1616) died 23 April 1616.

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. His own father sailed on Columbus's second voyage later that year.

How we know

Las Casas born Seville 1484; Columbus's return parade through Seville, spring 1493; his father Pedro sailed on Columbus's second voyage (September 1493).

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.

How we know

Dionysius Exiguus introduced Anno Domini dating c. 525 CE; Bede used and popularized it in De temporum ratione (725) and his Ecclesiastical History (731).

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.

How we know

Boethius d. c. 524 CE; his Latin translations of Aristotle's logic were nearly the sole basis for Aristotle in the Latin West until the later 12th century (~600 years).

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.

How we know

Papal bull Inter gravissimas (1582); Thursday 4 October 1582 was followed by Friday 15 October 1582, dropping ten days while keeping the weekday cycle unbroken.

Deep time

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.

How we know

Augustine's Confessions composed c. 397–400 CE — more than 1,600 years ago.

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 “the powers that be,” “the salt of the earth,” and “a law unto themselves” trace to his translation.

How we know

Tyndale's English New Testament (from the Greek) printed 1526; executed 1536; the King James Version (1611) carried over an estimated ~83% of his New Testament wording.

The court scholar behind our lowercase letters

Alcuin of York led the palace school of Charlemagne and helped drive a reform of handwriting. The clear, rounded script promoted in that revival — Carolingian minuscule — later became the model for Renaissance scribes and, through them, for the roman lowercase letters used in print and on screens today.

How we know

Alcuin of York c. 735–804 led Charlemagne's palace school; Carolingian minuscule (late 8th–9th c.) became the model for humanist minuscule and modern roman lowercase type.

From a Navarrese castle to an island off China

Born in the Kingdom of Navarre, Francis Xavier sailed east from Lisbon in 1541 and spent his next eleven years as a missionary along the coasts of Portuguese India, in the Spice Islands, and in Japan, which he reached in 1549. He died in 1552 on an island off the south China coast while trying to enter the mainland, having crossed tens of thousands of sea miles.

How we know

Francis Xavier 1506–1552; sailed from Lisbon 1541, reached Japan (Kagoshima) 1549, died on Shangchuan Island off Guangdong, China, in December 1552.

He produced the Latin Bible from a cave over three decades

Jerome, who produced the Latin Vulgate translation of the Bible, spent roughly the last 34 years of his life in Bethlehem, where tradition places his study in a cave beside the site venerated as the birthplace of Jesus. He learned Hebrew from Jewish teachers so he could work from the original texts.

How we know

Jerome c. 347–420; settled in Bethlehem c. 386 until his death; translator of the Vulgate who studied Hebrew under Jewish teachers.

He carried Egypt's desert monasticism to the south of France

Born around 360 near the Black Sea, John Cassian journeyed to Bethlehem and then to the monastic settlements of the Egyptian desert, studying under the Desert Fathers for years. After stops in Constantinople and Rome, he settled in Marseille around 415, where his writings transmitted Egyptian monastic practice to Western Europe.

How we know

John Cassian c. 360–435; studied among the Desert Fathers of Egypt, then founded monasteries at Marseille c. 415, transmitting Egyptian monasticism to the West.

A Christian theologian whose family served the caliph's treasury

John of Damascus lived his entire life within the Umayyad Caliphate; his family held senior posts in the caliphate's financial administration at Damascus before he withdrew to the monastery of Mar Saba near Jerusalem, where he composed his theological and hymn writings. He died around 749 — roughly a year before the Umayyad dynasty fell.

How we know

John of Damascus c. 675–749; his family (the Mansur) held fiscal posts in the Umayyad administration at Damascus; he became a monk at Mar Saba; the Umayyad Caliphate fell in 750.
