# Alphesiboea (daughter of Phegeus)

In Greek mythology, Alphesiboea (Ancient Greek: Ἀλφεσίβοια, romanized: Alphesíboia, pronounced), in some versions also called Arsinoë (Ancient Greek: Ἀρσινόη, romanized: Arsinóē, pronounced), is an Arcadian princess from the ancient Greek kingdom of Psophis, daughter of King Phegeus. Alphesiboea marries Alcmaeon after the murder of his mother, but he ends up deserting her for the love of another woman. Alcmaeon is then murdered by Alphesiboea's male relatives. Alphesiboea was one of the several owners of the necklace of Harmonia, a cursed artefact that brought ill fortune to its possessors.
Due to the great popularity of Alcmaeon's myth in antiquity, Alphesiboea is known to have appeared in many ancient dramatizations of the story, none of which are preserved today. At least three tragedies titled Alphesiboea are known to have been produced, alongside several Alcmaeons.

## Family

Alphesiboea was the daughter of the Psophian king Phegeus by an unnamed mother, sister to Axion and Temenus. She had a son, Clytius, and also an unnamed daughter by her husband Alcmaeon.

## Mythology

Alphesiboea lived in the court of her father with her brothers Axion and Temenus when Alcmaeon of Argos arrived in Psophis asking to be purified of the murder of his mother Eriphyle, whom he had killed for her indirect role in the death of his father Amphiaraus. Phegeus gladly helped him, and afterward he gave Alphesiboea as wife to Alcmaeon, who gifted the cursed necklace of Harmonia and her robe to his new bride.
They lived together for a while during which Alphesiboea gave birth to a son named Clytius, but Alcmaeon's curse for murdering his mother did not go away; either his disease worsened, or the ground grew infertile, disrupting agriculture and bringing a great famine to the land. He was commanded by Apollo's oracle to depart the land of Psophis at once, which he did. Alcmaeon eventually settled in Acarnania in the lands by the river Achelous. There he met and married the nymph Callirrhoe, daughter of the river-god, despite his wife being still alive in Psophis.
Callirrhoe however greatly desired the necklace and robe of Harmonia, which Alphesiboea still possessed back in Arcadia. So Alcmaeon was forced to return to Psophis and his lawful wife, where he was ambushed and treacherously killed by Alphesiboea's two brothers, who were acting on their father Phegeus’ command. In some versions, Phegeus himself personally killed Alcmaeon, as well as Alphesiboea's own daughter. When Alphesiboea reprimanded her male relatives for the unjust murder of Alcmaeon, her brothers locked her in a chest and sold her as slave to the Tegean Agapenor, falsely claiming it had been her who slew her husband. Although multiple accounts exist about the fate of her father, brothers and necklace afterwards, Alphesiboea typically disappears from the ancient narratives after her enslavement, and her ultimate fate is unknown.
The sole exception is the Elegies of Propertius, according to which Alphesiboea avenged the late Alcmaeon by killing Axion and Temenus. However, no other extant source suggests such turn of events; nevertheless, it is possible that Propertius knew a version in which the now enslaved Alphesiboea played an instrumental role in bringing down her male relatives with the help of Alcmaeon and Callirrhoe's sons, who are traditionally said to have been the ones to kill Phegeus and his sons to avenge their father.

## In ancient Greek drama

Several ancient tragedies dramatising the events at Psophis were written in classical antiquity, though none of them survives in anything more than fragments. The ancient playwrights Achaeus, Chaeremon and Timotheus each wrote a tragedy titled Alphesiboea (of which only few words or lines are preserved), while Sophocles wrote a similarly lost Alcmaeon, and Euripides Alcmaeon in Psophis. In Sophocles' version it seems that Alphesiboea was imprisoned by her brothers to prevent her from avenging Alcmaeon's death. Meanwhile Theodectes' lost Alcmeon appears to cover the events during the early days of Alcmaeon's arrival at Psophis, when he was still a relative stranger to Alphesiboea and giving her an account of his previous life and misdeeds, trying to justify his murder of Eriphyle.
