How Did Cleopatra Die? The Snake Bite and the Ancient Evidence

Cleopatra VII died in Alexandria in August 30 BCE, aged 39, after Octavian’s forces took the Egyptian capital and her partner Mark Antony killed himself. In the fullest surviving account, her attendants Iras and Charmion were found dying or already dead beside her. The best-known story has Cleopatra dying from a venomous snakebite. Ancient writers, including some relatively close to the events, were much less certain about how she died.

She had governed Egypt for more than twenty years as its last effective Ptolemaic ruler. The Ptolemies were a Macedonian Greek dynasty established in Egypt after Alexander the Great. With Cleopatra gone, the kingdom lost its independence, and Octavian gained control of its grain, wealth and position in the eastern Mediterranean. Three years later he became Augustus, Rome’s first emperor. Octavian had political reasons to shape the account of her final days, long before the stories became legend.

There is strong ancient testimony that she took her own life. One early writer reports both a snakebite and a poisonous ointment as competing explanations. Others describe figs concealing a snake, a hollow comb, marks on the arm or a poisoned hairpin. Some of the authors openly admit that the truth was unknown. Toxicology offers reasons to question particular versions, but no surviving evidence identifies a definite substance, instrument or animal. The differences between these accounts matter as much as the details they share.

How Cleopatra lost Egypt to Octavian

Cleopatra’s reign had long been entangled with Roman political struggles. During the contest for the Egyptian throne, she allied herself personally and politically with Julius Caesar; their son Ptolemy XV Caesar was known as Caesarion. After Caesar’s assassination in 44 BCE, she joined forces with Mark Antony, one of the leading Roman commanders fighting for power. Antony controlled much of Rome’s eastern sphere and needed the money, ships and other resources Egypt could supply. Their partnership was also personal: the couple had three children together.

Octavian, Caesar’s adopted son and political heir, was Antony’s chief rival. Portraying the conflict as a war against the foreign queen Cleopatra allowed him to present a struggle with another Roman as a defence of Rome. Their forces met at the Battle of Actium off the western coast of Greece in 31 BCE. Marcus Agrippa played a central part in commanding Octavian’s victorious fleet. Antony and Cleopatra escaped the defeat, but Antony’s remaining military support began to fall apart.

Winning at Actium did not give Octavian immediate possession of Egypt. Antony and Cleopatra returned to Alexandria and tried to retain their position while he advanced through the eastern Mediterranean. In 30 BCE his invasion reached Egypt. Alexandria, founded by Alexander the Great and developed by the Ptolemies into a major Mediterranean capital, was the couple’s final base. Ancient writers differ about the last fighting outside the city, but agree that Antony’s remaining resistance broke down when Octavian arrived.

For Octavian, taking the treasury and throne was only part of securing Egypt. He also had to decide what to do with Cleopatra’s surviving children. Caesarion’s public association with Julius Caesar made him an especially awkward dynastic rival to a man ruling as Caesar’s adopted heir. According to Plutarch, Caesarion was killed after his mother’s death. Her children with Antony were instead taken into Roman custody. Caesarion’s death and the captivity of the other children reveal how Octavian dealt with possible dynastic rivals after the conquest.

Antony’s death and Cleopatra’s last negotiations

Much of the familiar account of Antony’s final hours comes from Plutarch, the Greek biographer writing about a century later. In Life of Antony, chapter 81, Antony hears that Cleopatra has died and falls on his sword. Still alive, he learns that the report was false and asks to be taken to the monument where she has taken refuge. Because its doors are closed, Plutarch says Cleopatra and her servants pull him up through an opening with ropes. Antony dies after they bring him inside. The physical details and reported dialogue belong to a later biographical narrative, not an eyewitness transcript.

After arranging Antony’s burial, Cleopatra initially tried to starve herself, Plutarch says. He names her physician Olympus, reportedly a member of her circle and the author of a now-lost account, in connection with her thoughts of suicide. If Plutarch accurately drew on Olympus, he may have had access to testimony close to the events. All that survives, however, is Plutarch’s report in chapter 82. We cannot establish which parts of the biographer’s account came from Olympus or check the lost book for ourselves.

Octavian had good reason to want Cleopatra alive for a triumph. A Roman triumph displayed the victor, plunder and conquered enemies in a ceremonial procession through Rome. Capturing the Egyptian queen, long depicted by his supporters as a threat, would make the victory particularly visible. In Plutarch’s account of their meeting, she bargains over her property and hopes for favourable treatment. Plutarch depicts Octavian believing he had persuaded her to stay alive, while she remained intent on avoiding his control. That portrayal of their private calculation is part of his later account.

Plutarch then describes Cornelius Dolabella, a young associate of Octavian, warning Cleopatra that she and the children would soon be removed. She goes to Antony’s tomb and delivers a lament about the shame of being led through Rome as a captive. We cannot treat the speech as her exact words, since it survives through the biographer’s literary account. The danger of being paraded in a triumph was credible under Roman custom and recurs throughout the accounts of her death. Plutarch places the episode in Life of Antony 84.

Even Cleopatra’s final location is uncertain. Plutarch mentions her monument, Antony’s grave and guarded rooms; Cassius Dio speaks of a tomb and the palace. Both place the events in Alexandria without identifying a building archaeologists have located. Archaeological exploration of Alexandria’s submerged royal quarter has revealed important remains from the submerged Ptolemaic royal district, but none establishes where Cleopatra spent her final hours or where she was buried. Paintings that show a definite death chamber go beyond the physical evidence.

What the earliest ancient accounts say about her death

Strabo’s geographical work contains one of the earliest surviving accounts. He wrote while people who had known Cleopatra were still alive, and says that after Octavian took Alexandria she secretly killed herself either with an asp’s bite or by applying a poisonous ointment. In Strabo, Geography 17.1.10, the alternatives are part of Strabo’s own report. He says nothing about two attendants, marks on the arm or a basket of figs. The uncertainty was already present in an early account; modern doubts did not create it.

Horace wrote about Cleopatra soon after Octavian’s victory, but he wrote poetry, not a medical report. His Odes 1.37 begins with celebration of Rome’s escape from a threatening queen. Near the close he praises Cleopatra’s courage in choosing death rather than the humiliation of a triumph, and describes her handling fierce serpents. The poem demonstrates that the snake had become part of the Roman story quite early. It cannot tell us what was actually in the room where she died.

Strabo reported rival explanations. Horace gave his readers the serpent. Virgil’s depiction of Actium in the Aeneid 8.696–697 likewise gives deadly snakes a place in the queen’s imagined fate. Horace and Virgil wrote as Octavian’s victory was being incorporated into the political identity of the new regime. The asp offered an instantly recognisable image even without independent evidence of a snakebite. It was established as a literary symbol before the longest prose accounts of her death appeared.

In the early second century CE, Suetonius also reported that Octavian wanted Cleopatra alive for his triumph. In Life of Augustus 17.4, he describes calling for the Psylli after she died from what was believed to be a snakebite. Ancient authors credited this North African people with exceptional powers to counteract venom. The story shows how strongly the snake explanation had entered Roman tradition. Suetonius provides no medical confirmation that the Psylli possessed such powers or could have reversed the poisoning.

Plutarch’s basket of figs, and his admission of uncertainty

The detailed scene of Cleopatra’s death is told in Plutarch, Life of Antony 85. She bathes and eats, then receives a basket of figs from a man who has come from the countryside; guards examine it and allow it inside. After sending Octavian a sealed request to be buried beside Antony, she dismisses everyone except Iras and Charmion. Octavian sends men when he reads the message. They find the queen dressed in royal clothing on a golden couch, Iras dying at her feet, and Charmion attempting to straighten the diadem. Plutarch ends with an exchange attributed to Charmion, giving the scene the shape of a tragic final performance.

Yet Plutarch immediately acknowledges competing explanations in Life of Antony 86. Some said an asp was hidden in the figs; others put it in a water jar. Another version had Cleopatra carrying poison in a hollow comb concealed in her hair. No snake, he reports, was found inside, although people said traces appeared beside a window overlooking the sea. Reports also described two tiny punctures on Cleopatra’s arm. Plutarch refuses to choose among the versions. Later retellings often omit that uncertainty and present the figs as fact.

The reports of puncture marks are sometimes treated as physical proof. Plutarch did not examine Cleopatra’s body, and no contemporary medical report of its condition survives. He is passing on stories of marks that later readers have interpreted as either fang wounds or the result of a poisoned implement. The report that no snake was seen does not demonstrate that anyone carried out a complete search. Neither detail gives us a secure forensic observation.

Plutarch also says that Cleopatra appeared with an asp in an image displayed during Octavian’s triumph. A model or picture of the dead queen could take the place of the living prisoner Octavian had wanted to exhibit. If the account is accurate, the snake was already part of the public representation of her defeat. That does not prove it caused her death. Plutarch adds that Octavian ordered Cleopatra buried in royal fashion with Antony and allowed honourable burials for her attendants.

Cassius Dio and the poisoned hairpin

Cassius Dio wrote in the early third century CE, more than two hundred years after Cleopatra died. His Roman History 51.13 describes arrangements for her death, a sealed letter used to send away a guard, and her choice to wear royal ornaments. He stresses how her suicide thwarted Octavian’s wish to parade her alive through Rome. Dio gives the reader a connected account of the final hours, but one assembled from traditions already circulating for generations.

Dio himself concedes in 51.14 that no one knows clearly how Cleopatra died. An asp was supposedly smuggled in a water jar or flowers, according to one version. Another attributed her death to a hairpin coated with poison, which entered the body when it scratched her arm. Dio also describes Octavian examining her body and sending for the Psylli, who could not revive her. His account of the poison’s effects cannot identify its chemical composition.

Modern retellings sometimes merge Plutarch’s hollow comb and Dio’s poisoned hairpin into one concealed needle, although the ancient accounts describe different objects. The objects and the Greek words used to describe them have prompted scholarly discussion; neither was recovered and neither writer identifies a poison. The hairpin remains a proposed explanation for the reported marks. Nor should two late accounts automatically be counted as separate eyewitness confirmations when both depend on a long history of retelling the same event.

Despite their disagreements about the means of death, the accounts point toward suicide. Strabo says Cleopatra killed herself; Horace honours her refusal to submit to a triumph; Plutarch and Dio describe preparations for her death; and Suetonius reports that Octavian wanted her alive. Their authors had different aims and many wrote within the victors’ tradition. Together, they make suicide the leading historical explanation, while providing no comparable agreement about the method.

Could an Egyptian cobra have killed Cleopatra?

The ancient word asp cannot confidently be translated into the name of one modern snake species. Greek and Roman categories for venomous snakes were not zoological classifications. Egyptian royal symbolism included the rearing cobra or uraeus, a sign of protection and kingship. Because of that association, Cleopatra’s snake has often been identified as the Egyptian cobra, Naja haje. It is a plausible identification within the story, but the word used by ancient authors cannot by itself establish the animal’s species.

Concealing a live cobra also presents a practical problem. An adult Egyptian cobra can be large enough to be difficult to hide in a small basket of fruit without alarming a carrier or guards. François Retief and Louise Cilliers argue in their 2005 study of Cleopatra’s death that the idea of one snake killing Cleopatra and both attendants is especially hard to explain. They favour another means of poisoning. Their reasoning tests the plausibility of the traditional narrative, but it does not supply direct evidence of what happened in Alexandria.

The problem of concealing a cobra does not eliminate every snakebite scenario mentioned in the sources. Plutarch also mentions a water jar, while Dio includes flowers. Neither requires a single snake to have bitten all three women or provides reliable timings for the attendants’ deaths. It is possible to propose a snakebite for Cleopatra and another poison for her servants, but there is no direct support for that combination either. Such a reconstruction would require assumptions the surviving accounts do not substantiate.

Cobra venom can attack the nervous system, producing paralysis or respiratory failure, but its effects and timing are not uniform. A 1976 clinical report by Warrell, Barnes and Piburn records different courses after bites attributed to Egyptian cobras, including one fatal case within two hours and another in which neurological symptoms developed later. The report does not allow a diagnosis of Cleopatra from the literary descriptions, and it does not make death from a cobra medically impossible. Plutarch’s queen lying composed on a couch is a narrative image rather than a clinical examination.

Similar limits emerge in a 2021 review in Toxicology Reports, which discusses species, venoms and Ptolemaic traditions while identifying difficulties with the standard story. Snakebites vary greatly; statements that all fatal bites involve severe swelling, prolonged agony or a slow death may confuse cobra poisoning with the effects of vipers. Modern toxicology can test whether proposed scenarios are plausible. Without Cleopatra’s remains, a contemporary clinical record or an identifiable toxin, it cannot determine the cause of her death.

Why poison is plausible, but the substance is unknown

Poison through another means was already suggested in antiquity. Strabo named an ointment, Plutarch described a hollow comb and Dio mentioned a pin. Each alternative removes the difficulty of smuggling a live snake past the guards. A vessel or implement could conceivably have held poison beyond the guards’ notice. The descriptions of Cleopatra and two attendants dying around the same time fit the possibility of coordinated poisoning, but the sources do not establish exactly when each died or how the substance might have been administered.

Alexandria was known for physicians, intellectual activity and exchanges of knowledge throughout the Mediterranean. Cleopatra’s court could plausibly obtain medicinal and poisonous substances in such a city. Access to these substances would tell us neither which poison she used nor whether she understood its effects. In Life of Antony 71, Plutarch claims she experimented on prisoners with different poisons and venomous animals when considering methods of death. The claim might preserve knowledge from court circles, reflect hostile traditions or foreshadow the ending in Plutarch’s narrative. There is no surviving independent record of those alleged experiments.

Suggestions of plant poisons, mixtures of drugs or substances swallowed or introduced through wounds remain speculative. No ancient author supplies a recipe, dose or finding from an examination of the body. Dio’s description of a poison that was harmless on intact skin but deadly once it entered through a scratch is itself a literary report, not a sound chemical specification. Hemlock, aconite and opium have all figured in proposed mixtures, but no named combination has been established as the agent that killed Cleopatra.

Retief and Cilliers consider non-snake poisoning more likely, partly because the attendants reportedly died with Cleopatra. Others also doubt the snake story, without reaching agreement on a specific poison. Some writers have suggested that Octavian ordered her killed because her death served his interests. Yet the principal narratives say he intended to keep her alive, and no contemporary evidence demonstrates a murder order. His political advantage is not evidence of assassination. Suicide remains better supported than either murder or any particular method of self-poisoning.

Why the snake became Cleopatra’s enduring image

The snake story also drew strength from symbols that audiences already understood. Egyptian royal crowns carried the uraeus, associated with the protective goddess Wadjet. Cleopatra belonged to the Macedonian Ptolemaic dynasty while also using Egyptian sacred imagery and associations with Isis. A cobra could suggest Egypt and legitimate kingship at once. We have no evidence that Cleopatra selected an asp to make a religious statement. That reading comes from the symbolism later associated with her death.

Roman interpretations gave the serpent a different setting. Octavian’s supporters had presented Cleopatra’s wealth and eastern royal power as threats to Rome. Horace’s poem belongs to that political atmosphere, despite ending with admiration for her courage. Scholarship on Octavian’s portrayal of Antony and Cleopatra explores the way Antony and Cleopatra were depicted in contrasting Roman and eastern terms. We cannot show that Octavian invented the asp account. We can trace how the snake became prominent in representations associated with his victory.

Plutarch’s account of the triumph suggests that the image of the queen with an asp reached public display early, if his testimony is accepted. Later writers and artists could show a serpent against Cleopatra’s arm or breast and make the subject instantly identifiable without recounting her negotiations, Actium or the disputed causes of death. The same animal also carried Egyptian royal associations and, in European painting, became part of a frequently eroticised portrayal of Cleopatra inherited from earlier traditions.

The later artworks show how the story spread, but offer no medical evidence about her death. Guido Cagnacci’s Death of Cleopatra, dated by the Pinacoteca di Brera to 1660 to 1662, arranges the figure for dramatic effect. Painted more than sixteen centuries after Cleopatra’s death, it reflects seventeenth-century interests in classical subjects, the human body and death. It supplies no independent testimony for a snakebite in Alexandria.

Edmonia Lewis made a strikingly different Death of Cleopatra in marble in 1876. Cleopatra is already dead on her throne, with an asp in her hand. The Smithsonian American Art Museum notes that Lewis broke with idealised depictions by confronting the physical reality of death. The sculpture attracted controversy before coming to be recognised as an important work of nineteenth-century American art. Lewis still included the snake because the established story made its meaning immediately clear.

Juan Luna’s large 1881 painting Cleopatra, now at the Museo del Prado, also presents the queen’s final hours. The museum notes the serpent and the artist’s use of Plutarch, alongside his additional dramatic inventions. Alongside the works of Cagnacci and Lewis, Luna’s painting shows how artists gave visual certainty to an ancient narrative whose details were disputed. These works document Cleopatra’s later image, while offering no way to resolve the ancient medical uncertainty.

What Cleopatra’s death changed

Cleopatra’s death completed Rome’s takeover of the independent Ptolemaic kingdom. Octavian governed Egypt through Roman officials, and its wealth and agricultural output became important to the emerging imperial regime. Caesarion, presented as Julius Caesar’s natural son, was killed. The children Cleopatra had with Antony went to Rome; Cleopatra Selene later married Juba II of Mauretania. The dynasty no longer ruled Egypt, though members of Cleopatra’s family continued their lives and political connections within the Roman world.

Octavian celebrated his victories in Rome in 29 BCE. Because Cleopatra was dead, traditions about the triumph describe an image of the queen displayed in place of a living prisoner. Roman poets and historians presented her defeat as liberation from a dangerous foreign ruler, supporting Octavian’s new political standing. In 27 BCE he was granted the name Augustus. He preserved many outward institutions of the Republic while establishing a system in which decisive authority rested with him.

Plutarch reports that Octavian granted Cleopatra a splendid burial with Antony, and other ancient accounts also describe them as buried together. No securely identified tomb has been found. An excavation producing structures or artefacts near Alexandria is not equivalent to a burial securely tied to the couple by inscriptions or context. Without identified remains, there is also no possibility of examining Cleopatra’s body to test the competing explanations of her death.

Cleopatra most likely arranged her own death to avoid captivity and humiliation in Octavian’s triumph. Several ancient authors support that broad conclusion, even while reporting incompatible methods. A snakebite remains possible, as do the ointment, hollow comb or poisoned pin mentioned in the sources. None has been demonstrated. The asp gained its apparent certainty through Roman literature and later art. The precise cause of her death remains unknown.
