Nothing actually happened in the year 50

There is no identifiable event in that single year. The National Library of Medicine dates Dioscorides's composition of the work to approximately 50 to 70 CE, and 50 is only where that window opens.

About 60 is a midpoint, not a documented publication year. The work was assembled over time, and no manuscript of this period has a release date.

827 entries across five books

What Dioscorides produced was a five-book Greek treatise, now conventionally known by its Latin title, dealing with the preparation, properties and testing of drugs.

It covered plants, animal products and minerals. One scholarly reference counts roughly 827 entries — more than 600 plants, 35 animal products and 90 minerals.

A typical entry gave names, origin and physical characteristics, preparation instructions, medicinal uses, possible harmful effects, and sometimes tests for fraudulent preparations.

Almost everything about the author comes from his own preface

Dioscorides said he examined plants directly where he could, questioned people during his travels, and consulted earlier written authorities. In the preface he criticized recent writers for disorder, speculation and insufficient attention to practical experience.

The place of composition is not securely known. He was associated with Anazarbus in Cilicia, and nearly everything else claimed about his life derives from that dedicatory preface and later testimony — including the familiar claim that he was a Roman army physician, which is an inference from his remark that he lived a "soldier-like" life.

Blame, redirected

After the Great Fire of Rome in 64, Nero moved to suppress rumours that he had ordered it by accusing Christians and subjecting them to elaborate punishments.

Tacitus says authorities first arrested people who confessed, then used their information to convict a much larger group — more for an alleged hatred of humanity than for arson. No exact starting day survives; the punishments followed the fire of July 64.

What one source describes

Victims were reportedly wrapped in animal skins and killed by dogs, fixed to crosses, or burned as nighttime illumination. Nero opened his gardens for the spectacle and appeared among the crowd as a charioteer.

Every one of those details comes from a single surviving narrative. They belong to Tacitus's Annals 15.44 rather than to multiple corroborating sources.

Peter is not in the account

Tacitus does not name Peter. Later Christian tradition holds that Peter was crucified under Nero, but historians cannot establish that he died during these post-fire executions.

The episode was also local. The evidence establishes neither an empire-wide anti-Christian edict nor a coordinated imperial campaign in 64.

Even the episode itself is argued over: Brent Shaw has challenged its historicity, and Christopher P. Jones defended Tacitus's account against him.

Midnight in an empty palace

In the small hours of 9 June 68, Nero woke to find the palace guard gone. Friends, attendants and even caretakers had abandoned their rooms.

The freedman Phaon offered him refuge at a villa between the Via Nomentana and the Via Salaria, near Rome's fourth milestone. Nero rode there in disguise with four attendants.

A grave dug to his measurements

He got inside by crawling on all fours through a narrow passage cut into the villa wall.

There he learned that the Senate had declared him a public enemy, and that he faced the traditional punishment — stripped, fastened in a fork, and beaten to death.

While attendants dug a grave to his measurements, Nero reportedly wept over and over about the artist the world was losing.

Epaphroditus guided the blade

As mounted men approached with orders to take him alive, Nero drove a dagger into his throat with the help of his private secretary Epaphroditus, and died shortly afterwards.

The whole final-hour narrative comes principally from Suetonius, writing decades later; its dialogue and small dramatic details cannot be independently verified.

There was no vacant throne. Galba had already been proclaimed emperor by the army, the people and the Senate before Nero's death was confirmed.

A dream, an embassy, a temple

A later Chinese Buddhist tradition dates the foundation of White Horse Temple at Luoyang to 68 CE, the eleventh year of Emperor Ming's Yongping era.

In that narrative, Emperor Ming dreamed of a radiant golden figure identified as the Buddha and dispatched envoys westward. They returned with Buddhist texts and monks, for whom the emperor provided the temple.

The legend is younger than what it explains

Modern scholarship classifies the "official introduction" story as a pious legend that arose centuries after the alleged event, with its formation placed around the third century and development in the fourth and fifth.

The dates assigned to the western mission wander between 60, 61, 64 and 68 depending on the version. The two famous monks, Kāśyapa Mātaṅga and Dharmaratna, appear only in developed versions from the late fifth century onward.

Buddhism was already there in 65

An edict concerning Prince Liu Ying of Chu is regarded as the first undisputed Chinese reference to Buddhist monks, laypeople and practices — and it dates to 65, before the temple's traditional founding year.

The standing complex cannot settle the question either: its surviving historic structures are from the Yuan, Ming and Qing periods.

Rome taken on 20 December 69

Flavian forces led in Italy by Antonius Primus captured Rome on 20 December 69. Vespasian himself was still in the East.

The 22 December in the entry does not match that chronology; Ronald Syme's reconstruction puts the capture, and Vitellius's death with it, on the 20th.

Down the Sacred Way with a sword under his chin

Soldiers found Vitellius hiding and bound his hands — Tacitus names the tribune Julius Placidus as the officer who dragged him out. He was marched in torn clothing through the Forum with a sword held under his chin so he could not hide his face from the crowd.

Tacitus says he was killed in a shower of blows at the Gemoniae. Suetonius adds that the corpse was dragged off with a hook and thrown into the Tiber. He was nearly 57.

Vespasian became emperor more than once

After Vitellius fell, the Senate bestowed the customary imperial powers and honours on Vespasian — who had already been counting his reign from his army's acclamation on 1 July.

There was no single uncontested moment when he became emperor. Military acclamation, the death of his rival, senatorial recognition and the imperial law were separate events, and the surviving bronze Lex de imperio Vespasiani is dated only broadly to late 69 or early 70.

Vespasian never invested the city in 69

In 69 Vespasian overran places near Jerusalem and returned to Caesarea, and then, Josephus says, stopped applying himself to the Judaean war after learning that Vitellius ruled at Rome.

Preparations, operations in the surrounding country, and an actual investment of Jerusalem are not the same event. He had three legions in Judaea and used them elsewhere.

Two oaths, two days apart

The Egyptian legions under Tiberius Julius Alexander swore allegiance to Vespasian on 1 July, and his Judaean army followed on 3 July according to Tacitus.

The sources disagree about which came first — Josephus gives the Judaean army priority and no exact dates — but the direction of travel is not in dispute. Vespasian redirected men and resources into the civil war against Vitellius.

A reprieve the city spent fighting itself

Jerusalem stayed in rebel hands through 69 and suffered fighting among rival factions, with Simon bar Giora and John of Gischala contesting control.

Only after the Flavian victory did Vespasian send Titus from Egypt to assemble the army that besieged Jerusalem in 70.

Eighteen days of earthworks, then the wall

Josephus dates the final fall of Jerusalem's Upper City to the night leading into the eighth of Gorpiaios, in Vespasian's second regnal year — 70.

The siege banks had taken eighteen days to build and were finished the day before. Battering rams opened the wall, and the defenders abandoned towers that Josephus considered effectively impregnable.

Standards on the towers, fires through the night

Roman troops planted their standards on the captured towers, went into the lanes, killed people they met, looted houses and set buildings alight. The fires burned on through the night.

Titus then ordered armed resisters killed and the rest taken prisoner, though Josephus says soldiers killed elderly and infirm inhabitants too. An officer named Fronto sorted the captives for execution, forced labour, arena spectacles, the triumph or enslavement.

What "8 Gorpiaios" does not settle

Josephus gives the date securely but never says which calendar he means — Macedonian, Julianized Macedonian, or Judaean lunar. Modern conversions include 2, 8, 20 and 26 September.

This was the fall of the Upper City, not the day the Temple burned; Josephus places that earlier, in the month Lous. Nor was Jerusalem the revolt's last stronghold — Herodium, Machaerus and Masada still had to be reduced.

A pine tree over the bay

Pliny the Younger, seventeen years old in 79, described the eruption column rising above Vesuvius in the early afternoon and spreading like the trunk and branches of a pine tree.

At Misenum his uncle, the fleet commander Pliny the Elder, first prepared to go and investigate. A plea from Rectina asking to be taken off by sea changed that: he ordered quadriremes launched and turned the trip into an attempted rescue.

Held at Stabiae

He reached Pomponianus at Stabiae, but falling pumice, earthquakes, a rough sea and a contrary wind kept the ships from leaving that night.

Pliny collapsed after a sulfurous smell and approaching fire drove the group from the shore. His nephew — who was not there — inferred that dust-laden air and poor respiratory health killed him; that diagnosis is not certain.

Which day, and what actually buried the towns

The first major phase ran 18 to 20 hours and deposited pumice and ash up to 2.8 metres deep at Pompeii. Pyroclastic density currents followed and devastated Pompeii, Herculaneum, Oplontis, Stabiae and their surroundings; a 2022 review reports total deposits at Pompeii of roughly 6 to 7 metres.

The traditional 24 August comes from the oldest and strongest manuscript family of Pliny's letter. Archaeological, botanical, numismatic, inscriptional and wind-dispersal evidence has led other researchers to favour autumn instead, with one multidisciplinary review proposing a window between 24 October and 1 November.

A circular letter with seven named destinations

The 96 on this entry is a reconstruction: no manuscript or colophon supplies a composition date.

What the text supplies instead is an address list. It places John on Patmos and commands him to write what he sees and send it to Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia and Laodicea — a Greek work written at once as apocalypse, prophecy and circular message.

Where the conventional date comes from

Most ancient and modern commentators date the book's present form to the last years of Domitian's reign, conventionally around 95–96 CE. A substantial minority argues instead for around 64–70 CE, or for composition in stages.

Irenaeus's second-century discussion is normally read as placing the vision near the end of Domitian's reign, though its grammar has generated debate. The book itself does not name a reigning emperor.

666, or 616

One ancient textual variant changes the book's most famous number from 666 to 616.

Many scholars connect 666 and the wounded-and-returning beast with Nero. That does not by itself settle the date — Nero-return legends continued circulating after his death.

An heir already on the Rhine

Nerva's principate ended with his death in Rome on the conventionally accepted date of 27 January 98. Cassius Dio's epitome gives its length as one year, four months and nine days.

Because Nerva had publicly adopted Trajan in October 97 and associated him with imperial power, Trajan became emperor with no competitive election and no civil war. He was away with the German armies at the time — ancient accounts describe him as governor or commander there.

A letter, not a ceremony

Cassius Dio records that the new emperor sent the Senate a letter promising not to kill or disenfranchise any good man.

Trajan did not hurry to Rome. The peaceful handover also had an ugly prehistory: Praetorian guards had mutinied in 97 and forced Nerva's hand before he chose a soldier-heir.

How firm is the date, and what did not happen on it

Recent Oxford scholarship dates the end of the reign to 27 January 98, but older chronologies give 25 January and some reference works begin Trajan's reign on 28 January.

The circumstantial story — a stroke first, then a fever, in the Gardens of Sallust — is widely repeated by modern references but is less securely supported than the plain facts of Nerva's death at Rome and Trajan's succession.

Trajan's eventual entry into Rome, his welfare measures, conquests, building program and canal work were not events of 27 January 98.

Nothing is documented for 96

No consulted source records a Buddhist council, schism, proclamation or creation of a separate religion in 96 CE.

Scholarship dates early Mahāyāna only in broad terms, with evidence spanning roughly the first century BCE through the early centuries CE.

What the evidence actually consists of

The oldest datable evidence singled out by Oxford's survey is a first-century Prajñāpāramitā manuscript. It establishes neither an event in a particular year nor an origin in a particular region.

The first firmly dated Chinese evidence comes later still: Lokakṣema's translation of the Aṣṭasāhasrikā Prajñāpāramitā, completed in 179 CE.

Same monasteries, same ordination codes

Current scholarship describes early Mahāyāna as plural and institutionally intertwined with existing Buddhist ordination lineages, not as a sect that broke away on a known date. Adherents kept their established lineages rather than adopting a distinct Mahāyāna Vinaya.

Mahāyāna and Mahāsāṃghika are not interchangeable either; the simple Mahāsāṃghika-offshoot theory has largely been abandoned. Nothing can be shown to have changed in India specifically during 96 CE.

Nothing begins in 100

No consulted archaeological or textual source records the Chinese general populace taking up paper in 100 CE. There was no launch, no decree, and no sudden replacement of bamboo, wood and silk that year.

Archaeological analyses place genuine hemp paper in China in the second and first centuries BCE, so manufacture predated the listed year by generations.

Much of it was not writing paper

Some early Han specimens were coarse and unsuitable for writing — one of the larger primitive-paper sheets from Juyan measures 21 by 19 centimetres.

The surviving objects also come from tombs, frontier sites and official contexts. They cannot establish what proportion of ordinary people used paper, and "general populace" has no measurable definition in the claim.

105, and then the third century

The traditional textual milestone falls later: the Book of the Later Han credits the court official Cai Lun with making paper from bark, hemp waste, cloth and fishing nets, conventionally dated to 105 CE. That is a court report about improved materials, preserved in a later official history.

Institutional sources place widespread Chinese use later still, at around the third century CE.
