Probably legendary, reputedly flourished 4th century B.C.E., Rome
The story of Philotis is recounted in Plutarch’s life of Romulus (circa C.E. 75). In 390 B.C.E, when Rome was besieged by the Gauls, some of the enemy troops demanded the city’s women in exchange for peace. While the Romans attempted to find a way to appease the Gauls, a slave named Philotis proposed to organize the female slaves of the city to pose as Roman matrons, intoxicate the Gauls, then send up a flare signaling the Roman troops to attack. The deception worked and Philotis and her compatriots were granted freedom in return for their service to Rome.
