The Last Ptolemaic Queen of Egypt Who Killed Herself at Alexandria in August 30 BCE With Either an Asp or a Mixture of Hemlock, Aconitum, and Opium

Cleopatra VII Philopator (69–30 BCE) had been co-ruler of Ptolemaic Egypt with three successive male relatives (her brothers Ptolemy XIII and XIV, then her son Caesarion) from 51 BCE. She had been the political and military partner of the Roman triumvir Mark Antony from 41 BCE. The 31 BCE Battle of Actium off western Greece — where the combined Egyptian-Antonian fleet was defeated by Antony’s fellow triumvir Octavian — had effectively ended the Hellenistic Mediterranean order.

Antony and Cleopatra retreated to Alexandria. Octavian’s army arrived outside the city in late July 30 BCE and entered Alexandria on 1 August 30 BCE essentially without resistance. Antony, who had received false reports that Cleopatra was already dead, stabbed himself in the abdomen the same day. He was carried, still living, to Cleopatra’s mausoleum, where he died.

Cleopatra was negotiating with Octavian for the next eleven days. The negotiation appears to have been substantively two-sided: Octavian wanted her alive so he could parade her in his Roman triumph, while Cleopatra wanted either favourable surrender terms or sufficient time to arrange her suicide. Both got partial outcomes.

The asp story

The conventional account — the one that appears in Plutarch’s Life of Antony (written approximately 110 CE, almost 140 years after the events) and in Cassius Dio (3rd century CE), and that William Shakespeare used in Antony and Cleopatra (1607) — is that Cleopatra concealed an Egyptian cobra (Naja haje) in a basket of figs brought into her bedchamber on 10 or 12 August 30 BCE and presented her arm to the cobra. She died of cobra envenomation alongside two of her ladies in waiting (Iras and Charmion), all three within a few minutes.

The story has several physical problems.

— The Egyptian cobra is not small. An adult specimen is approximately 1.8 metres long. Concealing it in a fig basket is physically difficult. — Cobra envenomation in human subjects is not normally simultaneous or rapid. Symptoms develop over thirty minutes to several hours, with the victim conscious and progressively unable to breathe. Plutarch’s “all three women died in a few minutes” is inconsistent with the venom’s pharmacokinetics. — The Egyptian cobra has a single venom yield per strike of approximately 175 mg, which can kill one adult human reliably. Killing three women — Cleopatra and her two attendants — would require either three separate strikes (requiring the cobra to maintain envenomation capacity across all three) or a different mechanism for the attendants.

Modern toxicological consensus is that the asp story is at least partly mythological. The asp is the kind of detail that 1st-century CE Roman literary tradition was likely to apply to a death scene; the cobra had specific Egyptian religious associations (it was the symbol of pharaonic divinity, the uraeus on the pharaonic crown).

The Schaefer hypothesis

The German classical historian Christoph Schaefer published in 2010 the most-debated modern reconstruction of Cleopatra’s death. Schaefer argued from a combination of textual reanalysis (early sources closer to the events than Plutarch) and pharmacological analysis (the symptoms recorded in the sources fit several alternative mechanisms better than cobra envenomation) that Cleopatra most plausibly killed herself with a deliberately-prepared poison mixture.

The proposed mixture: hemlock (Conium maculatum), the classical Greek Socratic poison, which produces paralysis and respiratory failure; aconitum (Aconitum napellus, wolfsbane), which produces cardiac arrhythmia; and opium (from Papaver somniferum), which produces sedation and respiratory depression. The combination would produce a quick, calm, painless death — exactly the kind of death the contemporary sources describe Cleopatra as having arranged in advance.

The mixture would also explain the simultaneous deaths of all three women. They could have shared the same vessel.

The Schaefer hypothesis is not universally accepted. The pharmacological reconstruction is plausible but cannot be confirmed without physical evidence; Cleopatra’s body has never been located.

What Octavian got

Octavian had wanted Cleopatra alive for his Roman triumph. He arrived at the mausoleum on the morning of (probably) 12 August 30 BCE to find her dead. According to Plutarch she was lying on a gilded couch in full pharaonic regalia. Charmion was still alive and was adjusting the queen’s diadem; Iras was dead at her feet. Charmion died moments after the Roman guards entered the room.

Octavian arranged for Cleopatra’s body to be buried alongside Antony’s in her mausoleum, in keeping with what he understood to have been her instructions. The mausoleum’s location at Alexandria has never been securely identified by modern archaeology. The 21st-century excavations at the Taposiris Magna temple complex outside Alexandria, led by Kathleen Martínez, have produced extensive evidence consistent with an elite Ptolemaic burial complex but have not yet confirmed it as Cleopatra’s site.

Cleopatra’s son Caesarion — Cleopatra’s child by Julius Caesar — was executed on Octavian’s orders within weeks. Her three children by Antony (Alexander Helios, Selene II, and Ptolemy Philadelphus) were spared and transported to Rome, where they were raised in the household of Octavian’s sister Octavia. Selene married the Numidian prince Juba II and became Cleopatra Selene II of Mauretania.

Octavian was declared Augustus by the Roman Senate in January 27 BCE. He had become the first Roman emperor. The Hellenistic Mediterranean world had ended.

Was she beautiful?

The contemporary visual record — the Egyptian and Roman portrait coins of Cleopatra’s reign, including coins minted at Alexandria, Cyprus, and Antioch under her authority — depicts a woman with a strong aquiline nose, a heavy chin, and a fairly thin face. The portraits are stylised but not flattering. They do not match the conventional Renaissance and modern Hollywood depiction of Cleopatra as a notable beauty.

Plutarch records that her contemporaries described her as not exceptionally beautiful but as exceptionally charismatic — “the contact of her presence was irresistible; the attraction of her person joined with the charm of her conversation.”

The 21st-century historical consensus is that the Cleopatra-as-great-beauty identity is a substantially Renaissance and modern construction with limited basis in the contemporary visual record. She was politically formidable, multilingual (she reportedly spoke nine languages), and the only Ptolemaic ruler to speak Egyptian as well as Greek. The beauty narrative is a separate question.
