Come, thou who art burdened by so many great misfortunes, utter once more thy sad lamentations surpass the kingfishers and the sweet swift nightingales, for thy fate is more grievous than theirs. Dusk at the Domus Tiberiana on Palatine Hill. A bronze plate falls from the table. The guests in the dining hall hush. A man stumbles. His vision doubles as delirium slips him closer to the floor. He stammers for help. The most powerful man in the ancient world is dying, slain by a deadly little mushroom. But who poisoned him on the final night of his tumultuous life? I am Aaron J. Reardon and this is Plant Murder. Each episode we delve into the fascinating and deadly plants that have left their mark on human history in this Emperor Claudius of Rome and the Death Cap. Mushroom murder, though it have no tongue, will speak with most miraculous organ. As Claudius lay gasping for breath on the cold marble floor, his body racked with convulsions, the evidence of his murder was already slipping away. What killed him? The poison in the molten wine? The stuffed dormice? The oysters? Or his favorite, a tiny hidden killer slipped onto his plate of mushrooms. As we peel back the layers, ask yourself, was Claudius of such ill health that he was one of the rare emperors that died of natural causes, a so called syco mortem, a dry death? Or was he one of the many that died of foul play? It's 10-13-54 CE we're on Palatine Hill in Rome. A chilly night in autumn. The Domus Tiberianus, the house of the Emperor. And we're standing in the dining hall. A sprawling chamber with marble columns veined with purple and gold rising toward a painted ceiling. Flickering light from bronze sconces dance across frescoes, casting long shadows. Murals of Dionysian revelry. Nymphs and satyrs caught in celebration. Faces twisted into masks of joy mocking the tragedy about to unfold. Below the table, a low slab of dark wood. Platters of roasted dormice, honeyed figs and coated olives. The air heavy with spiced meat. A small mixed group of family and trusted staff reclining on the triclinium as they sip wine. Let's hold this moment. Let's stroll around the room and get a good look at everyone who is here with us in this dining hall. I see a wife, a soldier, a eunuch, a doctor, two sons and a plate of mushrooms tumbling to the floor. They are all looking at the sudden commotion raised by this man here at our feet, collapsing in front of them, our victim, Emperor Claudius. Before we get to the guests, let's take a look at this poor, quivering fool. His tunic disheveled and stained with vomit. His posture hunched. Thinning hair streaked with gray. Sallow skin stretched too tightly across his face. Deep lines etched into his brow, around his mouth. His eyes are bloodshot, watery. They search about in confusion and fear as the poison takes hold. His hand claws at the edge of the table as he pulls at the cloth collapsed on the floor, bent and cowering. This. This is the Emperor of Rome. The gods do not always smile upon those who are born into greatness. We're in the Palatine Gallery. We're not far from the house. It's 13 years earlier. A bright, crisp January, and in just a moment, right there, Claudius, obnoxious nephew, is about to be stabbed to death in broad daylight. And his nephew's wife and daughter smashed to bits. You might know his nephew's name. Caligula. I thought so. One emperor slumped in the dust, leading out with that why me? Look on his face. And where is Claudius right now? He's about to become Emperor because of his nephew and the Praetorian Guard, which is like the secret service for Roman emperors. While Caligula was still warm, they raced down the halls of the palace, found Claudius cowering behind a tapestry and yanked the poor fool into the imperial seat because they wanted to stay in power. Claudius was never supposed to be emperor. A tragic Figure I don't mean to be cruel. He had a very difficult life which shaped his character. Claudius entered the world with both immense privilege and crushing stigma. He was the grandson of Mark Antony, the war hero who shacked up with Cleopatra. Shakespeare has a great play about that. Claudius was born into a powerful and noble family. But unfortunately he was born with afflictions. Possibly Tourette's or maybe cerebral palsy. Claudius had a stammer, limp and uncontrolled outbursts of speech and uncontrollable laughter. In the shadow of more charismatic figures, Claudius was dismissed, mocked and left on the margins of Roman political life. He was taunted by everyone. His own family would mock him, throw food at banquets and tickle him awake with a feather. Whenever he fell asleep at the table, he had a difficult go of it. So are you getting the picture? It was an embarrassment to his rich and powerful family and so was pushed out of view and the butt of everyone's joke. But he persevered, writing histories mainly. Perhaps he found escape from an unkind world. Once merely a consul to Caligula, never considered a true contender For Emperor, at 50 years of age, Claudius now stood as the unexpected ruler of Rome, yanked into the imperial seat. And now from that seat, he tumbles to the floor at our feet. Fetal. Brutal. Stomach cramps. Dying. Why, after 13 years as emperor, would the people around this table want him dead? Despite his accomplishments well into adulthood, Claudius was constantly mocked and manipulated. Was he simply a victim? Or did he know the conspiracy brewing around him? Let's look at the faces around the table. Which one of them looks the most guilty? A wife? A soldier? A eunuch? A doctor, his two sons and a plate of mushrooms tumbling to the floor? Let's start with the most obvious. His wife. Great power and greater ambition have nothing in common with self Estreit. This striking woman with a commanding presence at the end of the table is his wife, Agrippina the Younger. Her dark braids pinned up with a golden diadem, a rich adorned pleated stola. She is 39 years old at this dinner and she is one of the most compelling figures in history. It's 39 CE. We're on the volcanic shores of the island of Pontiac. The rocks are razor sharp and life is very difficult on this small island. One of the only ways to survive is to dive for sponges. And just under the waves over there, you can just make out Agrippina the Younger. She's not married to Claudius yet, she's just 24. Here she's been Exiled to this island after the plot of the Three Daggers, a conspiracy to assassinate her brother Caligula. And yes, if you're paying attention, that means that Claudius was her uncle. She'll be here for another two years before Claudius brings her back to Rome. She spends every moment on this island scraping to survive. It's a far cry from her upbringing in a wealthy family. Hunting for sponges is difficult work. They have to hold a stone known as a scandalopetra, which helps sink them quickly to the seafloor. She has to work swiftly, staying underwater for as long as her lungs will allow. She could drown. There's shark attacks, she can get the bends. She can get entangled in seaweed or cut herself on the coral. Agrippina is a tough one. And her story reads like something from a dark myth. A young girl thrust into the violent heart of Roman power. Listen to this. Life on campaign in Europe as a child, married at 13 to a violent 30 year old man. He dies. She marries again. He dies under odd circumstances. Her brother goes nuts. He's forced into a possible incestuous relationship. Conspiracy. Thrown to exile on this sharp, isolated island. Dies for sponges to survive. She's brought back. Marries a man mocked for his afflictions, practices dark magic rituals and has underworld connections. That husband dies. She continues her obsession with the elevation of her son to emperor, all while ruling in parallel. It's almost impossible to find an account of Agrippina without the words ruthless or ambitious. Throughout, she navigated her way from exile to empress, pulling public opinion along with her. Why is Agrippina the primary suspect for Claudius murder? Well, she lived an impressive life. Seemingly fearless, she survived a cutthroat family, dynasty, exile, abuse and even her own assassination attempts. These powerful families had purges. They killed anyone who might be a threat, especially the stakes of noble lineage. Any claim for the throne. Her father murdered, her mother died in exile. Tiberius killed two of her brothers. And the third, Caligula, was stabbed to death in public. Her sisters were both dead. She was the only surviving member of her family. And like one of those sharks, Agrippina felt that if she stopped ascending, she would meet her end. Maybe she was so conditioned to that bloody environment that that was all she knew. Agrippina was Claudius fourth wife and niece. A marriage suggested by the Senate. An incestuous relationship. He had to change Roman law to make it happen. A marriage of convenience to unite the two main families of the Julio Claudian dynasty. It's fair to say that Agrippina came back to Rome with the express Mission to marry an emperor to secure her future. The only way to survive. She once got attacked for being too forward. When she publicly made a pass at Emperor Galba, his wife clocked her in the face. She seemed driven and fearless by all accounts, but possibly without much choice. We are going to go around this table, and you are going to see that everyone else is connected to Agrippina. And she has been positioned as the ringleader of a conspiracy with favors, promises, threats. She was already an empress at this point. Why would she need to kill Claudius? Well, what if I told you that Agrippina had killed before? Are all the pieces falling into place as she sees Claudius tumble to the ground? Or is that a look of compassion in her eye? And did we see Agrippina eat from the same dish of mushrooms that Claudius did? Was Agrippina the Younger, the Lady Macbeth of ancient Rome? Well, if she was, she couldn't do it alone. She would have had to recruit some accomplices. So, before we rush to judgment, a nation can survive its fools and even the ambitious, but it cannot survive treason from within. Here's the thing about Rome. It's a city built on indulgence, influence and blood. During the Julio Claudian dynasty, the palace is a place of paranoia. Dozens of poisonings have taken place. Purges, conspiracies and rivalries. The very figs on the trees have been coated in poison. And Tiberius Claudius Caesar Augustus Germanicus knew this better than anyone. The man lived his whole life in the shadow of sharper, crueler men. And this dinner had a few knives hidden behind their smiles. So let's look around this table again. A wife, a soldier, a eunuch, a doctor, two sons and a plate of mushrooms tumbling to the floor. The wife we know is Agrippina, who was the soldier in his purple cloak and shiny silver brooch that held it fast to the shoulder, the razor sharp gladius in its leather sheath, and a pugio dagger at the ready. This was not any soldier. This was Sextus Afranius Queres, the prefect of the Praetorian Guard, responsible for the Emperor's security and maintaining order in Rome. Burris is a career soldier who spent much of his time in politics. He tends to hover close to Agrippina and her son, almost like a surrogate father. He keeps a very close eye on the boy. He's 53 years old, his once dark hair turned mostly gray, cut short to match his neatly trimmed beard. Could the head of the Praetorian Guard have acted independently to remove Claudius? Possibly. Without Agrippina knowing No way. Burruss was fiercely loyal to Agrippina, who had positioned him to ensure her son's protection. However, Burrus owed his career to Agrippina, which complicates his role in Claudius death. As he watches Claudius falter, was he gripping his dagger to finish him off? Were his loyalties to the Empire or Agrippina? Why not just stab him like the others? We could assume that a violent death could destabilize the Empire and risk civil war. So it had to be something that looked like an accident. Burrus couldn't act alone, but he could have turned a blind eye. Maybe he loved her. Maybe they had an affair behind Claudius back and Burrus wanted him out of the way. I think he's wrapped around Agrippina's little finger and he's at the ready to do whatever she asks. Claudius wasn't despised the way Caligula was. Claudius did much good for the empire. So you couldn't just stab the guy to death at dinner. You'd have to make it look like an accident. So let's turn to the next in line. An accident like a poisoning is hard to prove, but you'd have to slip it past a key figure that every Emperor relies on. We're in the imperial kitchens. These are huge on the palatial grounds and they're staffed by dozens of slaves cooking day and night. It would be difficult to poison a dish in here because of the eunuch there. He's the trusted food taster. His name is Halotus and he's keeping a watchful eye on the preparation of all the dishes. He has a tenuous relationship with the Archimagirus, the head chef. Halotus would have sampled anything the Emperor would likely have eaten, especially his favorite dish of prepared mushrooms. Polotas almost blends into the decor. Now in his mid-40s, his deep set dark eyes seem perpetually watchful, scanning the surroundings with quiet intensity. His voice is higher pitched, lacking the deep resonance of most men. He's used to standing just out of view in the corner of your eye, confidently giving a nod that all the food has been tasted and tested and everything is set up exactly how Claudius likes. His slender, wiry frame moves quietly through the palace halls. His smooth, pale skin and lack of facial hair immediately mark him as a unit. Halodos was responsible for Claudius safety. How could Halodes Claudius, food taster, have let a poisoned dish slip past him unless he too was complicit? Halodus job was to taste every dish before Claudius ate it, ensuring the Emperor's safety Yet Claudius still died after consuming something. Was Halotus involved or did a savvy agent bypass him completely? While we don't have good reason to doubt Halotus loyalty, he was either complicit or someone else snuck a plate without him noticing. And since it was his job and he seemed quite good at it, we can assume that was less likely. However, there's one important thing about. Well, it's sort of an open secret. Claudius was an incredible glutton. He overindulged in vice, food, drink and gambling. He had bouts of indigestion so bad it drove him to near suicide side quite frequently. He had to be carried away from banquets, overstuffed to the point of being sick and stumbling drunk. Claudius also really loved snacks, so there was a constant stream of plates and goblets flowing past Helotus all day. See, if Halotus tasted everything on this table, how did he survive the tasting? Think through the scenarios. And while you do that, I'm going to give you one other possibility. What if it wasn't a dish? What if Claudius stuffed himself with food, got indigestion and it was used to hide what really killed him? See, there's something else mentioned in the historical accounts. A long poisoned bird's feather. What if the murder weapon was slipped down Claudius throat by a malevolent doctor, a wife, a soldier, a eunuch, a doctor, two sons and a plate of mushrooms tumbling to the floor? The doctor at this table is Claudius personal physician Xenophon. He has measured and sharp blue eyes set deep under heavy brows that give him an air of quiet authority. He's in his early 50s. Not much is known about Xenophon from history, but there's a very specific account of Xenophon slipping a feather down Claudius throat just before he died. So maybe it wasn't a poison dish of food at all. Maybe Claudius was held down, his jaw wrenched open and a poison feather pushed into his throat. Xenophon had been treating Claudius ailments throughout his life, and in middle age, Claudius health was degrading significantly. It's possible that instead of poison in the dishes, Xenophon gave Claudius something that reacted badly. Was it a conspiracy that Xenophon delivered the fatal poison to subvert Halotus? Or did he accidentally overdose Claudius on medicine? Or was it possible that Xenophon and Agrippina had colluded to slowly poison Claudius over time and tonight was just the night he said succumbed? We're not sure. Let's see what other details come to light to help us decide what we are Going to see is that with Claudius in declining health, it's very possible that the cunning people around the table saw the writing on the wall, secured their alliances, to set their fate. A fate, when Claudius, inevitably passed, would be in the hands officially of one of his two sons. Agrippina could move the chess pieces around, but the title of emperor had to go to one the boys. A wife, a soldier, a eunuch, a doctor, two sons and a plate of mushrooms tumbling to the floor. This is Britannicus, his youngest, just shy of his 14th birthday. He has not grown yet into. His full stature is framed by his short, tousled dark hair, his eyes wide and innocent. He carries a shadow of uncertainty, knowing his fate hangs in the balance. Tis an unweeded garden that grows to see things rank and gross in nature possess it. Mirleght. It's 48 CE. We are in the gardens of Lucullus, crawling over nearly 20 acres on the slope of the Pincian hill, a masterpiece of Roman landscaping. They're fed by a series of aqueducts that provide water to the numerous fountains over there. And these streams, they feed the figs and the olive and the pomegranate trees. And alongside all of this blooming jasmine and the roses, the grandeur is unmatched in all of Rome. An ultimate symbol of wealth and luxury. Carefully tended terraces and statues that reflect power and elegance of the Empire. Britannicus. Here, he's just nine years old. He's a scared little boy trying to make sense of the world around him. Something terrible is about to happen. His mother has been sentenced to take her own life. There she is, there, strikingly beautiful. Her usual solid veneer is shaking. Her name is Valeria Messalina. She comes from a rich and powerful family and she truly captured the dark imagination and gossip of Rome. While married to Claudia, she threw lavish orgies here in these imperial gardens, flaunting her sexual prowess and indulgences. And then, in a move that could only be described as utterly reckless, she married Gaius Syllis while still married to Emperor Claudius in a mock ceremony that was instigating a type of soft couple. Claudius, embarrassed cuckolded, ordered her death. And as you can see, she doesn't have the courage to take her own life, so that enormous centurion will do it for her. Britannicus is a relatively mild and stable individual compared to the wild and bloodthirsty members of his family. Grew up in palace life only to watch his father execute his mother. And he was, for a while, the only successor to the Empire. Did Britannicus resent his father for effectively killing his mother. It seems very reasonable. Did he look across this dining table every night at his stepbrother who hated him and a scheming stepmother and felt his own father couldn't protect him anymore? It's unlikely, but not impossible that Britannicus poisoned his father or the revenge of his mother Valeria, and then hoped he could curry enough favor to quickly install himself. But that's a lot for a 13 year old boy. And also by this time, Claudius was starting to show Britannicus more favor. But he's just a boy. He lost his mother. His father is a drunk who's now on the ground in pain. He's being intimidated by his vicious older brother and he never stood a chance. He must have lived these moments in such fear and insistence, certainty. And you would too if you had a stepbrother like Lucius. Look at him glare across the table, toying with a sharp silver knife. Let's look at the adopted son. He's 16 years old and he hates his little brother. He's pompous, self absorbed and spoiled and has inherited all of his mother's guile. His hair is light blonde, his eyes blue and somewhat menacing. His neck is over thick, his belly prominent, his legs slender. A spoiled older bully of a brother. Agrippina fawns over him and Burrus is very protective of him. His name is Lucius, but you might know him better as Nero, future Emperor of Rome. Yes, the burning, fiddling Nero. He is the adopted son of Claudius. Agrippina had him before she was exiled to a different father at just 16. He was already showing signs of impatience and cunning. He knew Claudius was on the decline, his health in trouble. It would only be a matter of time. His mother was already aligning the support he would need to take the imperial seat. And there was just one person in the way. His whiny little brother, Britannicus. Claudius biological son. Nero could have been impatient and gone around his mother's back. He could have bribed porters. It's entirely possible that Nero and Agrippina had discussions about how to rid the world of Claudius together. But maybe Agrippina wanted to wait and Nero made other plans and Agrippina was just witness. We can imagine Agrippa Pina realize in what's happening, while Nero has a smirk as his stepfather falls to the ground. Rome is a superstitious and mystical place. Sacrifices to gods, rituals and spells and Agrippina practiced magic herself are reflections of the sorceress Morgana and her son Mordred from Arthurian legend. Both pairs deeply entwined and using sorcery for lust, betrayal and manipulation. Enchantments, rituals and offerings to the gods. You see this snake bracelet on Nero's upper arm? That's a protection charm. When Valeria Messalina was still alive, she actually sent assassins to kill Nero. But they were scared off by a snake under his pillow. Well, it turned out it was just a snakeskin and Agrippina had it changed into a magic charm. She met with soothsayers and made sacrifices. Did they predict Claudius death? She also had contacts in the underworld. And this is where things get very interesting. Did Agrippina turn to dark magic to rid Rome of her husband? There's someone else at this banquet that we didn't see before. They're looking at us from the shadows. We're in the back streets at the tabernacle, the shops at the central marketplace, the Forum Romanium in the valley between the Capitoline and Palatine hills. Normal trade of wares are out in the daylight, as you can see, but in the back rooms and undercover are clandestine dealings. There was one collaborator in that dining hall and we couldn't see her. But in a room in the back of this innocent herbarium is one of the most dangerous women in ancient Rome. She's a professional poisoner and her name is Locusta. How much for these figs? 2. 2. Locusta is an enigmatic figure in Roman history. She is believed to have been born in Gaul. Emerging from the city's criminal underworld in the first century, she became an expert in the deadly craft of poisoning, mastering the use of herbs, venoms and toxins to create concoctions that could kill efficiency. Maybe Agrippina hired her. Or maybe Nero went behind his mother's back. Or maybe Xenophon got his more potent elixirs from the dark markets. Locusta was so good at her trade that in the future, Nero and Agrippa. Agrippina will hire her again to craft a poison to kill poor little Britannicus. And then Nero, when he finally gets sick of his mother, will hire Locusta to poison her. But it doesn't work. So we're pretty sure that Claudius, growing attachment to Britannicus, threatened the future Agrippina had fought to secure for Nero. With Claudius alive, Britannicus would be his successor. The banquet, surrounded by those Claudius trusted, offered the moment for Agrippina to act decisively and ensure Nero's place on the throne. Locusta tainted a dish of mushrooms Claudius favorite, laced with a carefully crafted poison. The Emperor, unaware of the danger ate the meal that would lead to his slow and painful death, clearing the way for Nero's rise. If Agrippina knew that mushrooms were Claudius favorite meal, they would be the subtle delivery device for his undoing. A wife, a soldier, a eunuch, a doctor, two sons and a poisoner looking from the shadows. So we've met all of the dinner guests, but we haven't been introduced to this deadly plate of mushrooms. So exactly what is it that we're looking at spilling on the floor? Let's have a look at this little mushroom. What if I told you that the death cap mushroom isn't even a plant, but an alien species from space bent on world domination? Plant Murder will return after these special messages. Welcome back to plant murder. Claudius vs. The Death Cap Mushroom 10.13.54 CE Roman Emperor Claudius of failing health forces a lining against him. The stresses of managing a growing empire on his shoulders indulged his appetites in a great dinner. And it is well known that at that dinner he was poisoned by a plate of death cap mushrooms. We're in the Ciminian forest on a moonlit night. It's an ancient woodland located to the north of Rome, near modern day the Turbo. It's dense and mysterious. The death cap mushroom, which thrives in wooded areas with broadleaf trees such as oak and chestnut, is found here. And we need to be quiet as that hooded figure there is collecting them under the COVID of night. If you're the type of person who might scold me for calling a mushroom a plant and we're in the right place. They are a fungus and they have their own kingdom. Mushrooms are closer to animals than plants. These cell walls of the mushroom are made of chitin, the same substance found in the exoskeletons of insects. They breathe in oxygen and exhale carbon dioxide. Unlike plants, which produce their own food, mushrooms lack chlorophyll. They get nutrients from organic matter. So we'll carry forth and we'll treat this little mushroom as a plant pro tempore for the purpose of this episode. So this is Amanita phyllodes. I'm not casting a spell. It's a deadly death cap mushroom. They're easily mistaken from edible varieties. And they're responsible for 90% of all mushroom related fatalities. The poison works slowly, often taking days to claim its victims. They have been transported around the world, spreading this little lethal fungus far beyond its native forests, expanding its empire. Are you ready for a conspiracy? Did aliens kill Claudius? Don't laugh. Recently they hooked up a mushroom to a robot body, and it quickly figured out how to crawl. Mushroom spores have been found at every layer of our atmosphere, and they are so resilient, they could survive in the vacuum of space. If you entertain the theory of panspermia, you might wonder if spores traveled here from distant galaxies. Alien invaders quietly establishing a foothold on Earth. And if you enjoy a good paranormal conspiracy, perhaps you'll indulge in the idea that mushrooms have a vast underground network, a biological telegraph system through which they can communicate and manipulate events on a global scale, even by Roman intrigue. It's a stretch of any imagination, but who am I to dismiss the mysteries of the natural world? What I do know is this. Never forage for mushrooms unless you know what you are doing. The death cap has led to countless fatalities throughout history. These guys have taken down figures as prominent as Pope Clement vii, King Charles VI of France and composer Johann Schobert, among others. Now, you might want to pay attention to this part. The poisoning from death cap mushrooms begins with mild symptoms. They usually appear 6 to 12 hours after ingestion. The initial signs include nausea, vomiting and pain in the abdomen. So these symptoms may subside for a brief period, which is a false sense of recovery. As the toxins continue to damage the liver and kidneys, more symptoms emerge, including jaundice and confusion. Without treatment, liver and kidney failure can occur. They lead to coma and death within seven to 10 days. But something doesn't completely add up, does it? Hold on to that for later. To Romans, the hedonists, food was a celebration and the rich loved to eat mushrooms. So was it Claudius, fourth wife, the calculating and mysterious Agrippina, which orchestrated the deadly feast in which she slipped the death cap mushrooms into the dining hall. Lurking poison and treacherous wounds are more to be feared than open warfare. A wife by political convenience, his niece, an awkward, incestuous relationship. And a woman that ruled in parallel, obsessed with placing her son as emperor. A soldier, Burrus. Not just a soldier, his bodyguard, guard, in charge of his personal safety, loyal to Nero. And Agrippina, the lotus, not just a eunuch, but the royal food taster in charge of his safety, who might have looked the other way. A doctor, A physician. Xenophon, in charge of his failing health and might have delivered the killer blow. A biological son, Britannicus, 13, who was threatened by his older brother being pushed out and was shrewd enough to know the writing was on the wall. An adopted son, 17, Nero, cunning and impatient and ended Claudius to get his hands on the imperial seat. Locusta, a poisoner in the shadows who loved her trade, and a mushroom that's not a plant but a lethal fungus. The circumstances of Claudius death were recorded by three historians, Tacitus Suetonius and Cassius Dio. Much later than the events in question, Tacitus tells us the tale of conspiracy that Agrippina, Helotus and Locusta, and even Xenophon the court physician, are all embroiled. And here is the actual account from Tacitus.
