At the beginning of October 1347, 12
0:03
Genoese galleys pulled into the harbor
0:05
at Messina. The Franciscan chronicler,
0:07
Michele da Piazza, wrote that anyone who
0:10
only spoke to the sailors was seized by
0:12
a mortal illness. Within 2 years, some
0:15
Italian cities would lose about 60% of
0:18
their people.
0:19
The unexpected turn is not that death
0:21
arrived on ships. It is that the thing
0:24
that made the Black Death so deadly was
0:26
not a cartoon superbug.
0:28
Teeth from a London burial ground,
0:30
sequenced in 2011, carry Yersinia pestis
0:34
sitting near the ancestor of the strains
0:36
we still have. 12 galleys at Messina.
0:42
If you believe the famous version, the
0:44
story starts like this. The ships stink.
0:47
Men are already dying on the decks.
0:49
Messina tries to drive the galleys off.
0:51
It is too late. The sickness walks
0:54
ashore. Buboes, the size of a hazelnut,
0:57
then an egg in the groin, the armpit,
0:59
the neck. Fever, vomiting of blood. 3
1:03
days and the body is a problem for
1:05
whoever is left. Michele says the
1:07
pestilence ran from October 1347
1:10
into April 1348 on Sicily.
1:14
Fugitives take it to Catania. The island
1:16
empties in pieces. That is the chronicle
1:19
voice. Treat it as a public record of
1:21
panic, not a lab notebook. The ships
1:24
were real, the harbor was real, the
1:27
count of 12 is the number the Sicilian
1:29
text gives. Other versions say three or
1:31
four. Say about. What is not in dispute
1:34
is the direction, the Black Sea and the
1:37
Eastern trade. Then the Italian ports,
1:39
then the rest of the map. The story.
1:43
Everyone knows here is the version you
1:45
were handed in a classroom. Dirty
1:47
medieval cities, black rats, rat fleas,
1:50
a Mongol army at Caffa in 1346,
1:53
catapulting corpses over the walls, the
1:56
first bio-weapon, and then Genoese
1:58
sailors carrying the gift west. God's
2:01
arrows. Jews poisoning wells. Bad air,
2:04
miasma, a fog you could smell.
2:07
Flagellants whipping themselves in 1349
2:10
to buy a pardon.
2:12
If you believe it happened exactly that
2:14
way, you still have to explain the
2:16
speed.
2:17
Europe in the 1340s had on the order of
2:20
75 to 80 million people.
2:23
Common estimates put the dead between
2:25
about 30 and 50%. Some modern tallies,
2:29
working parish by parish, push the
2:31
European share toward about 60%. That is
2:34
not a winter flu. That is a society
2:37
losing every other person or worse in
2:40
about 5 years, 1347 to 1351.
2:44
The classroom rat is not nothing. It is
2:46
not the whole machine.
2:48
Three clocks in one body.
2:51
Yersinia pestis is a bacterium. In 1894
2:55
in Hong Kong, Alexandre Yersin isolated
2:58
it during a later plague. The same
3:00
organism, not a myth. It has at least
3:02
three clinical clocks. Bubonic, a flea
3:05
bite, an incubation of about two to six
3:08
days, swollen lymph nodes, untreated
3:11
case fatality often about 40 to 70%.
3:14
Septicemic, the blood, a faster crash,
3:17
very high fatality without treatment.
3:20
Pneumonic, the lungs, person-to-person
3:23
on breath, about 1 to 3 days, untreated
3:26
fatality near 100%.
3:29
The Black Death was not one cartoon. It
3:32
was a stack. A naive population with no
3:34
recent memory of this bug. Winter
3:37
crowding that helps a lung form. Summer
3:39
fleas that help a bubo form. Ships that
3:42
move a reservoir faster than a horse.
3:45
You in a 1348 room do not get a
3:48
diagnosis. You get a lump, a cough, or a
3:51
house that is suddenly quiet. Modern
3:54
antibiotics can break this. They did not
3:56
exist. That is not mystery. That is a
4:00
missing tool.
4:01
Five children
4:03
in Siena
4:04
in 1348, a Sienese chronicler named
4:08
Agnolo di Tura wrote that he buried five
4:10
of his children with his own hands. No
4:13
priest, no paid grave, pits in the city,
4:16
hundreds a day, earth thrown over, then
4:19
more.
4:20
Florence, in some counts, lost on the
4:22
order of 60%.
4:24
London, hit in late 1348, is often put
4:28
near half. Venice, Florence, Siena,
4:32
Avignon. The numbers in old tables run
4:34
to tens of thousands in single cities,
4:37
and they conflict because medieval
4:39
census is not a spreadsheet, say about.
4:42
The named case is not a legend. It is a
4:44
father in a specific year, in a specific
4:47
town, doing the last job himself. That
4:50
is what deadly looks like on the ground,
4:53
not a map with arrows, a household that
4:55
runs out of hands before it runs out of
4:57
bodies.
4:58
East Smithfield in London was opened in
5:01
late 1348 or early 1349 as an emergency
5:05
ground by the Tower.
5:06
Excavation in the 1980s recovered about
5:09
750 to 790 burials of an estimated
5:12
2,400.
5:14
Trenches and single graves still
5:16
ordered, which is not the movie of
5:18
bodies dumped like trash. It is a city
5:21
trying to keep a riot while the riot is
5:23
losing.
5:24
The teeth under London.
5:27
And it gets worse if your picture was a
5:29
unique medieval monster.
5:32
On October 12th, 2011, Nature published
5:34
a draft genome of Yersinia pestis,
5:37
reconstructed at about 30-fold coverage
5:39
from East Smithfield victims securely
5:42
dated to 1348 to 1350.
5:45
The organism sits very close to the
5:47
ancestral node of the strains that still
5:49
infect people.
5:50
The 1347 wave looks genetically like the
5:54
main event that spread the ancestor of
5:56
later human plague. The bug was not a
5:58
cartoon super virulence that then
6:00
vanished. Host, climate, fleas, lice,
6:03
crowding, and three clinical forms did
6:05
the rest. Later work has argued that
6:08
human fleas and body lice, not only the
6:10
rat flea Xenopsylla cheopis, may have
6:13
carried more of the European burden than
6:15
the textbook drawing allowed. That is a
6:18
live argument. Mark it as about what the
6:20
teeth close is the older claim that the
6:23
Black Death was some other disease
6:25
entirely, anthrax or a mystery virus.
6:28
The pulp says pestis. The lethality was
6:31
the meeting, not a lost strain of magic.
6:34
The machine around the germ.
6:37
A bacterium does not empty a continent
6:39
by itself.
6:40
Trade did part of the work, grain,
6:42
cloth, furs, the Black Sea, Messina,
6:45
Genoa, Marseille by November 1347, then
6:49
overland. A person can move a pneumonic
6:52
case faster than a rat. A ship can move
6:55
both. Labor collapsed, fields went
6:57
unharvested. The Statute of Laborers in
7:00
1351 tried to freeze English wages after
7:04
the shortage made survivors expensive.
7:06
That is the economic scar, paper trying
7:08
to hold a market that had lost its
7:10
people.
7:11
Pogroms were the social scar.
7:14
In Strasbourg on February 14th, 1349, a
7:18
massacre of Jews. Estimates often near
7:21
900 to 2,000 burned on the charge of
7:24
well poisoning. The plague did not need
7:27
a well. It needed a story that named a
7:29
neighbor. Flagellant columns walked in
7:32
1349 as if pain could be a vaccine.
7:35
None of that treated a bubo. All of it
7:38
shows why the death toll is not only a
7:40
biological number, it is biology plus a
7:42
society with no germ theory, no
7:45
isolation that worked at first, and a
7:47
habit of turning fear into a weapon.
7:50
What they did instead,
7:52
Ragusa, later Dubrovnik, ordered a
7:55
30-day landing wait in 1377, then 40.
7:59
The quaranta that gives us quarantine.
8:01
That is later, after the first smash. In
8:04
1348, the tools were fires, vinegar,
8:07
flight, closed gates that opened again
8:09
when food ran out, and physicians who
8:11
still talked in humors. Flight spread
8:14
the map. Closed gates starved the poor
8:16
first. The caffa corpse catapult, told
8:19
by Gabriele de Mussi, may or may not be
8:22
how the port was seated. Siege,
8:24
overcrowding, and fleas would have been
8:27
enough. If you believe the catapult as
8:29
the whole origin, you still have 1338
8:32
and 1339 gravestones near Issyk-Kul in
8:36
Kyrgyzstan naming pestilence years
8:38
before Messina.
8:40
The second pandemic has an Asian
8:42
prologue. Europe met it as a surprise.
8:45
That surprise is part of the body count.
8:48
What does not happen?
8:50
The Black Death does not restart
8:51
tomorrow because you heard a galley
8:53
count. Modern plague still exists in
8:56
animal reservoirs. It is not 1348.
8:59
Antibiotics, hospital isolation, and
9:02
surveillance change the clock. A flea
9:05
bite in the American West is a case
9:06
report, not a continent. Pneumonic
9:09
clusters are still a medical emergency.
9:11
They are not an automatic 60%. Jews did
9:14
not poison wells. Miasma was not a gas
9:17
you could ban. Flagellation did not
9:19
lower a titer. A city with sewers is not
9:22
immune by cleanliness alone, and a city
9:24
without them was not doomed only by
9:26
dirt. Rats were a piece. People were a
9:29
piece. Ships were a piece. The genome is
9:32
not a prophecy. Europe's population
9:34
recovered over generations. Wages moved.
9:37
Some villages never came back. That is
9:40
history. It is not a forecast that your
9:42
street goes quiet in 3 days. The number
9:45
that was not magic. The number to keep
9:47
is not 12 galleys. It is about 30 to 60%
9:51
depending which ledger you trust of a
9:53
continent in 5 years from an organism we
9:56
can still name in a tooth. Agnolo's five
9:58
children are one house. East
10:00
Smithfield's 2,400 estimated graves are
10:04
one city's overflow.
10:06
The 2011 genome is the turn that kills
10:08
the legend of a lost superbug.
10:11
The deadliness was a stack. Three clocks
10:13
in one bacterium, a population that had
10:15
not met it, a trade net that moved
10:18
faster than any doctor, and a social
10:20
machine that buried, fled, and blamed. A
10:23
mass grave can still be orderly. A
10:26
chronicle can still be a father's hands.
10:28
If a video about a medieval plague left
10:30
you restless, that unrest
