Chilonis (Greek: Χιλονίς) was a Spartan princess, daughter of Leotychidas, wife of Cleonymus, then Acrotatus, with whom she had Areus II.
[1] Her much older husband Cleonymus, a son of Cleomenes II, had not been allowed to succeed to his father's throne because of his violent and tyrannical behaviour, and had spent many years away from Sparta as a soldier of fortune.
[2] Chilonis preferred death to a return to her husband; in Plutarch's account of the battle, she kept a rope tied around her neck ready to commit suicide in the case of defeat.
[3] With the help of their women, the Spartans, led by Acrotatus, were able to withstand the attack,[4] until the return of the king from Gortyn.
Chilonis and Acrotatus had a child, who later ruled as Areus II, Agiad King of Sparta.
