This queen was said to be as fair as Helen of Troy—but she was no political pawn

After Alexander the Great’s death in 323 B.C., the generals who had supported him on his campaigns carved up his vast empire to create new dynasties in Egypt, Syria, Macedonia, and Thrace. But warmongering and dissent soon took hold among these new kingdoms; alliances were as capricious as they were short-lived. Women of various royal families were occasionally used as bargaining chips in the negotiations necessitated by these volatile political maneuvers. This was to be the fate of Arsinoe, daughter of Ptolemy I: onetime general under Alexander and, later, first Hellenistic king of Egypt.

Arsinoe grew up in the lap of luxury in the royal court of Alexandria and likely received a thorough education. At about 16 years old, she was married off to Lysimachus, ruler of Thrace and much of Anatolia, and her father’s former military comrade. By this time Lysimachus was approaching 60, had been married several times, and already had adult children, including Agathocles, whom he had named his successor. Arsinoe went on to have three children with her aging husband: Ptolemy, Lysimachus, and Philip. She held the title of queen of Thrace for almost 20 years and assumed the mantle of queen of Macedonia after her husband’s invasion of the land in 285 B.C.

Palace intrigues

In a dramatic turn of events in 283 B.C., Lysimachus was implicated in the execution of his own son and heir, Agathocles. The story goes that Lysimachus had Agathocles killed for conspiring against him with Seleucus I Nicator, another of Alexander’s generals, but some ancient sources point to Arsinoe as the instigator. Perhaps she wanted to get rid of Agathocles to clear the way for one of her own sons to inherit the throne, or perhaps, fearing that when Agathocles succeeded his father he would view her sons as potential rivals, Arsinoe acted preemptively to protect them from a grisly fate. Whether or not the queen was involved, Agathocles’ death triggered a series of tragedies that would culminate in the same gruesome fate from which the queen purportedly tried to save her sons.

Along with her children and supporters, Agathocles’ widow, Lysandra, fled to Seleucus, who was in Babylonia, and entreated him to avenge her husband’s murder. Seleucus jumped at the chance, and invaded Lysimachus’s territories in Asia Minor. At the Battle of Corupedium in Lydia, Lysimachus fell. Fearing for her safety and that of her children, Arsinoe took refuge in the city of Cassandreia in Macedonia. It was there that she received an unexpected offer of protection from her half brother Ptolemy Ceraunus.

“The Thunderbolt”

Before marrying Berenice, Arsinoe’s mother, Ptolemy I had been married to a distant cousin of Berenice’s, Eurydice, with whom he had several children. One of these children, Ptolemy Ceraunus, was convinced that, as the eldest son of Ptolemy I, he was the rightful heir. His father, however, appointed the son he would later have with Berenice, the future Ptolemy II, as co-ruler. Ptolemy Ceraunus left Egypt for Syria, where Seleucus welcomed him into his circle of confidants. But Ceraunus repaid the welcome with treachery, murdering Seleucus in a sudden attack that would earn him his epithet Ceraunus (“the Thunderbolt”).

With Seleucus out of the way, Ceraunus presented himself to his half sister Arsinoe as her savior, and asked her to marry him. Although Arsinoe had doubts about his intentions, she ultimately accepted the proposal, believing Ceraunus’s promises to protect her children. In reality, Ceraunus wanted to take over the kingdom of Lysimachus, and there was no better way to legitimize this aspiration than to marry his widow.

After the wedding ceremony, Arsinoe invited Ceraunus to the city of Cassandreia, which was still under her control. She made sure that the town’s temples, altars, and houses were decorated in honor of the distinguished visitor. When Ceraunus arrived, Arsinoe sent her two youngest sons to welcome him at the city gates. But as soon as Ceraunus entered Cassandreia, he ordered his men to kill the boys and take over the city.

Realizing her mistake, Arsinoe desperately tried to save her sons. The Roman historian Pompeius Trogus recounts how “she time and again offered herself to the assassins; often with her own body she shielded her boys’ bodies in her embrace and tried to take the wounds that were aimed at her children.” Her struggle was in vain. Ceraunus’s men did not even allow her to bury her sons. Arsinoe fled, and sought refuge in Egypt with her other brother, her father’s heir, Ptolemy II. Ceraunus’s triumph was short-lived. Just over a year later, he was captured and executed during a battle against the Gauls led by the formidable Bolgios.

Queen of the Nile

In Egypt, Ptolemy II granted Arsinoe the protection he had promised and asked for her hand in marriage, despite the two being full siblings. Incestuous relationships tended not to scandalize the Egyptian population, as sibling marriage was common among the pharaohs. But for the Greeks living in Egypt, things were very different. In the words of the historian Plutarch, many considered the marriage “unnatural and unlawful,” and some critics spoke out in public, including the poet Sotades, who paid with his life for a poem addressed to Ptolemy II that included the line: “You’re sticking your prick in an unholy hole.” Many members of the court, however, celebrated the royal pairing, such as the poet Theocritus, who compared the marriage to the union of the sibling-gods Zeus and Hera.

In fact, the marriage between Arsinoe and Ptolemy II marked one of the most prosperous periods of the Ptolemaic dynasty. It was a time when the magnificent city of Alexandria became the cultural and commercial center of the Mediterranean, and when Hellenistic Egypt controlled the greatest territory. There is evidence that Arsinoe actively participated in the government of the kingdom, especially in foreign policy, and that she was an important promoter of art and learning. Although it’s unclear how much power she had, it’s likely to have been considerable.

Death and deification

Ptolemy bestowed many honors on his wife. He named a number of cities after her, both in Egypt and in other regions, such as Cyprus, Asia Minor, and even the Arabian Peninsula. He minted coins with Arsinoe’s name and image, erected statues of her, and dedicated all kinds of tributes to her, both during her lifetime and after her death.

The greatest honor was deification. Ptolemy decreed Arsinoe a goddess; she was worshipped as such throughout the land, boasting her own priests and temples. When she died around 270–268 B.C., the king and many ordinary people staged displays of respect and affection. Ptolemy even established a festival in her honor called the Arsinoeia. Despite her short reign as queen of Egypt, Arsinoe left her mark on the country and the dynasty. Her cult lasted for centuries, and her image became the model of the Hellenistic queen par excellence, the symbol of a flourishing and powerful Egypt. Her successors tried to emulate her, commissioning sculptures of themselves in a similar style. Only the last Ptolemaic queen of Egypt, the great Cleopatra VII, would rival her.
