InGreek mythology,Theano (/θiˈænoʊ/;Ancient Greek: Θεανώ) was the wife ofAntenor and apriestess ofAthena atTroy during theTrojan War.

Theano was a daughter of KingCisseus and QueenTelecleia ofThrace,^[1] and thus the sister of QueenHecuba, wife of KingPriam of Troy. She was the wife ofAntenor^[2] and by him, mother of many sons, including:Archelochus,Acamas,Glaucus,Helicaon,Laodocus,Polybus,Agenor,Iphidamas,Coon,Laodamas,Demoleon,Eurymachus andMedon; and a daughter,Crino.^[3]

The household ofAntenor and Theano advocated for peace and advisedHelen's return to the Greeks. Because of their support— which some claimed was treason— the Greeks spared their household when they sacked the city.^[4][5] In Book VI of theIliad, alongsideHecuba and other Trojan women, Theano offered a gift and plea to Athena for the survival of the city, but was rebuffed.^[6]

After the sack of Troy, one story has Theano and Antenor sailing withAeneas to Italy and founding the city ofPadua.^[7] Another story has her taking thePalladium, an image of Athena that had fallen from the sky and supposedly provided Troy its protection, with her.^[8]
