Theano of Troy

In Greek mythology, Theano (/θiˈænoʊ/; Ancient Greek: Θεανώ) was the priestess of Athena in Troy.

Family
Theano was the daughter of the Thracian king Cisseus and Telecleia and thus the sister of Queen Hecuba, wife of King Priam of Troy. She was the wife of Antenor and by him, mother of many sons possibly including, Archelochus, Acamas, Glaucus, Helicaon, Laodocus, Polybus, Agenor, Iphidamas, Coon, Laodamas, Demoleon, Eurymachus and Medon; and a daughter Crino.

Mythology
The household of Antenor and Theano advocated peace and advised Helen's return to the Greeks. Because of their support (some say treason ), the Greeks spared their household when they sacked the city. One story has Theano and Antenor sailing with Aeneas to Italy and founding the city of Padua. Another story is that she took the Palladium, an image of Athena that had fallen from the sky and supposedly provided Troy its protection, with her. In Book VI of the Iliad, with Hecuba and the Trojan women, Theano offered a gift and plea to Athena for the life of the city, but was rebuffed.
