Welcome to toldinstone. This video explores three ancient conspiracy theories: an outbreak
0:07
of hysteria in classical Athens, a plot at the court of Alexander, and a crusade against
0:14
a mysterious Persian cult. But before I tell those stories, I have an announcement.
0:20
I have started two new YouTube channels to complement my videos here on toldinstone.
0:27
One of the new channels is called Scenic Routes to the Past.
0:32
Scenic Routes is a travel channel, which follows my journeys to various historical destinations.
0:38
Unlike toldinstone, it is not focused exclusively on ancient history. The first two videos,
0:44
which you can view now, document my quest to find a railroad lost in the Alaskan wilderness.

My other new channel is called Toldinstone footnotes.
0:56
This channel hosts episodes of my podcast, in which I interview some of the most interesting
1:01
historians working today. It also features Q & A videos, livestreams, and much more.
1:09
If you could take a moment to subscribe to my new channels, I would deeply appreciate
1:14
it. Thank you for your time – and now, without any further ado, ancient conspiracy theories.
1:22
A conspiracy theory arises in the hazy gulf between suspicion and fact. It is discussed,
1:30
accepted, rejected, dismissed. It may be definitively debunked; it may even be proven. But it exists
1:38
independently of any verifiable source, living in the court of public opinion, feeding on
1:45
itself. Ancient history is full of conspiracies, in
1:49
the sense of coordinated plots against power. Famous examples include the Catilinarian Conspiracy,

an attempt – thwarted by Cicero – to overthrow the Roman Republic; the Pisonian Conspiracy,
2:02
which sought to supplant Nero; and the Barbarian Conspiracy, an apparently concerted attack
2:08
on Roman Britain by the Picts, Saxons, and Irish.
2:13
There are fewer instances of conspiracy theories in the most familiar sense – i.e., the assumption
2:19
that a secret organization is pulling strings behind the scenes. Speculation about those
2:25
in power, of course, is as old as civilization itself, and our sources reverberate with rumors
2:32
about the undue influence of courtiers and relatives of rulers. Claims that the whole
2:38
political system was being subverted, however, tended to emerge only in periods of acute
2:44
crisis. The affair of the herms in Classical Athens
2:48
is one of the best-documented examples. Athens, famously, had a democratic government, in
2:55
which a large part of the citizen body participated. In combination with a lively tradition of
3:02
criticizing public figures – epitomized by the comedies of Aristophanes – the immediacy
3:07
of the democracy made the schemes and scandals of prominent politicians a popular conversation
3:14
topic. The most talked-about of all Athenian politicians
3:19
was the brilliant, charming, and utterly unscrupulous aristocrat Alcibiades. A scion of the same
3:26
family that had produced Pericles, Alcibiades made his name by promoting an aggressive foreign
3:31
policy against Sparta and her allies. He was admired for his compelling speeches
3:37
before the Assembly, and for such political stunts as entering no fewer than seven awesomely
3:42
expensive chariots in the Olympic race. His dissolute private life, however, led many
3:48
Athenians to distrust him, and set the stage for the affair of the herms.
3:54
Herms were small statues placed at crossroads and beside doorways. They consisted of a simple
4:00
stone pillar, topped by a god’s head and garnished with a prominent erect phallus.
4:07
In the spring of 415 BC, just as the Athenian government, spurred by Alcibiades, was about
4:12
to launch a vast armada to conquer Sicily, nearly all the herms in Athens had their noses
4:18
and phalluses knocked off. While this might seem like a harmless prank,
4:24
the mutilation of the herms threw Athens into a frenzy. Herms, after all, were images of
4:31
the gods, and any injury to them was sacrilege. That so many divine images had been damaged
4:37
at the outset of the Sicilian expedition seemed a bad omen, and a conspiracy theory arose
4:43
that the herms had been broken by a secret cabal that sought to destroy the government.

5:58
Back to Classical Athens. A public investigation brought additional information to light: shortly
6:04
before the herms were mutilated, a group of young men had broken other religious statues
6:10
and mimicked the Eleusinian Mysteries, the most sacred Athenian ritual. One of the participants,
6:16
it was said, had been Alcibiades. It began to be whispered that Alcibiades had also been
6:22
responsible for smashing the herms, and that his acts of sacrilege were part of a plot
6:27
to overthrow the democracy. As one of the leaders of the Sicilian Expedition,
6:33
Alcibiades was forced to leave the city before he could clear his name. In his absence, the
6:39
conspiracy theory continued to grow, connecting the mutilation of the herms and violation
6:44
of the mysteries with an aristocratic scheme to replace the government. When a small Spartan
6:49
force was reported in the vicinity, it was immediately assumed that they had been summoned
6:54
by the conspirators. Arrests were made; armed patrols were posted in the city center; and
7:00
finally, Alcibiades himself was summoned back to Athens to be tried for his supposed crimes.
7:07
Although it’s entirely plausible that Alcibiades mimicked the mysteries with his friends, and
7:12
not impossible that he was associated with the men who mutilated the herms, there is
7:17
no reason to think that he was plotting to overthrow the democracy. Aristocratic coups
7:22
were a legitimate threat – there would be two within a decade of the Sicilian Expedition
7:27
– but Alcibiades had little to gain from overthrowing a government that had just awarded
7:32
him an important command. In this case, he seems to have been nothing more or less than
7:38
the victim of a conspiracy theory. To a degree that a democratic leader like
7:44
Alcibiades could only envy, monarchs dominated both public discourse and popular suspicion
7:51
in antiquity. The most familiar examples are the Roman emperors, whose plots, perversions,
7:58
and peccadilloes pervade our sources. Emperors were frequently implicated in conspiracy theories,
8:05
especially – and understandably – when their predecessors perished under suspicious
8:10
circumstances. Perhaps the most interesting conspiracy theory involving a classical ruler,
8:17
however, centers on the death of Alexander the Great.
8:20
Alexander died at Babylon on June 10, 323 BC, aged 32. According to his most reliable
8:28
ancient biographers, he had fallen ill ten days before, during or shortly after a wine-soaked
8:34
banquet. His illness began as a fever, mild enough – at first – for the king to ignore
8:40
as he prepared to invade Arabia. Within a few days, however, he had become too weak
8:46
to sit up or speak. Still burning with fever, he lapsed into a coma, and never woke.
8:52
An alternative tradition added dramatic details. At the final banquet, according to this version
8:59
of events, Alexander was draining a goblet of wine when he cried out in pain. Collapsing,
9:06
he was carried away by his friends, and lay in agony until the final coma overtook him.
9:12
Almost as soon as Alexander died, it began to be rumored that he had been poisoned. The
9:17
culprit, it was said, was Antipater, the king’s regent in Europe, who had sent his young son
9:23
Iollas to dose Alexander’s cup with a potion prepared by Aristotle.
9:28
Aristotle certainly had reason to resent Alexander. He had been the king’s tutor; and when the
9:34
Persian campaign began, he sent his nephew Callisthenes to accompany the Macedonian army
9:39
and write a history of its conquests. Alexander, however, proceeded to execute Callisthenes
9:46
on a trumped-up treason charge. As might be imagined, this did not improve his relationship
9:52
with the young historian’s uncle. According to the rumors that sprouted after
9:57
Alexander’s death, Aristotle had procured water from the bitter springs of the river
10:02
Styx, whose deadly water would dissolve any container besides the hoof of a mule. With
10:08
the connivance of Antipater, Antipater’s son Cassander, and a very literal drug mule,
10:14
the poison made its way to Babylon, and to the king’s cup.
10:17
The Styx water is legendary, and the involvement of Aristotle supremely unlikely. That Alexander
10:23
was poisoned, however, is not beyond the realm of possibility. Alexander’s mother Olympias
10:30
believed – or claimed to believe – that Antipater was responsible for her son’s
10:35
death. She executed several men on charges of involvement in the plot, and dishonored
10:40
the supposed poisoner Iollas by exhuming his body and scattering the bones.
10:45
Antipater’s son Cassander, Iollas’ brother, returned the favor by executing Olympias and
10:51
leaving her body to rot unburied. He also took vengeance on Hyperides, an Athenian orator
10:58
who had dared to propose honoring Iollas for poisoning Alexander. After Hyperides was captured
11:04
by Cassander’s bounty hunter, his tongue was cut out, he was executed, and his body
11:09
– like that of Olympias – was left to be devoured by the birds and beasts.
11:15
The dramatic sequence of accusations and murders that followed Alexander’s death does not,
11:21
of course, prove that the king was poisoned. Our most reliable ancient sources roundly
11:26
reject the theory, which seems to be a product of popular suspicion and political maneuvering.
11:33
Although we’ll never know for certain, malaria – exacerbated by alcoholism and old battle
11:38
wounds – is a far more likely culprit for Alexander’s death than poison.
11:45
Not far from Babylon, but more than half a millennium after the death of Alexander, the
11:49
deadliest of all ancient conspiracy theories began in a small Mesopotamian village, where
11:55
a prophet named Mani started to preach a new religion.
11:59
Mani’s creed, which we call Manichaeism, proclaimed a universal conflict between the
12:05
powers of Light and Darkness. To ensure the ultimate triumph of the Light, a chosen few
12:11
– the Elect – were called upon to renounce all worldly possessions and devote their lives
12:17
to rituals combatting the Darkness. It was the duty of all other believers – the Hearers
12:23
– to support the Elect with alms, and so gain a chance to be reborn as an Elect, and
12:29
finally escape the prison of the flesh. With the personal support of the shah, Mani
12:34
proselytized throughout the Persian Empire, proclaiming a religion that perfected and
12:39
replaced the teachings of Jesus, Zoroaster, and the Buddha. Missionaries were sent to
12:45
India, to the steppes of Central Asia, and into the Roman Empire.
12:49
Adda, one of Mani’s chief disciples, led the first Roman mission, which established
12:55
communities in the provinces of Syria and Egypt. Equipped with translations of Mani’s
13:01
scriptures and trained to engage philosophers and priests in theological debate, Manichaean
13:07
preachers gained converts rapidly, sowing cells of believers from Alexandria to Rome.
13:12
Traditionally, the Romans were tolerant of any religion that respected the established
13:17
social and political order. Sects that seemed to encourage rebellion or disloyalty, however,
13:24
were repressed. The most famous example is the Christian Church, but instances stretched
13:29
back to the Roman Republic, which had crushed the cult of Bacchus for inciting immoral behavior.
13:35
In 302, Diocletian was notified of disruptions caused by Manichaean preaching in the province
13:41
of Africa. The more the emperor learned about the new religion, the more alarmed he became.
13:47
Mani had been a friend of the Persian shah, the arch-enemy of all things Roman. To Diocletian
13:54
and his advisors, this seemed a clear indication that Manichaeism was nothing less than a Persian
14:00
plot intended to overthrow the Roman Empire. In an imperial edict, Diocletian proclaimed
14:07
that the Manichaeans were seeking to infect the “innocent, orderly, and tranquil Roman
14:14
people” with the “damnable customs and perverse laws of the Persians, as with the
14:20
poison of a malignant serpent.” Any Roman who converted to Manichaeism would be executed;
14:28
any official who supported the cult would be sent to the mines; and the Manichaean preachers
14:33
themselves were to be burned alive atop piles of their scriptures.
14:38
As the Great Persecution of the Christians would soon demonstrate, the provincial governors
14:43
responsible for enforcing imperial edicts were not always enthusiastic about doing so,
14:48
and most Manichaeans seem to have escaped punishment. Throughout the fourth century
14:53
and beyond, however, emperors continued to issue edicts stripping Manichaeans of their
14:58
civil rights, declaring them outlaws, and condemning them to death.
15:03
As the Roman Empire became Christian, the Manichaeans were branded heretics and corrupters
15:08
of the faith. St. Augustine – a former convert to Manichaeism – was the most famous of
15:14
the many Christian thinkers who attacked the so-called Persian heresy. Increasingly savage
15:20
penalties drove the sect underground, and eventually expelled it from the empire.
15:25
Manichaeism was never actually a Persian plot. Although Mani had indeed enjoyed court patronage
15:32
for a time, he had died in prison, and his religion was being persecuted in its native
15:36
land by the Zoroastrian priesthood long before Diocletian issued his edict.
15:42
Yet the Roman crusade against the Manichaeans lasted, with interruptions, for more than
15:47
two centuries. In keeping with the late imperial synthesis of church and state, it became an
15:53
issue of both policy and belief. But it had its origins in the fatal simplicity of a conspiracy
16:00
theory. Click the link in the upper right for the
