Creusa was the wife of Jason. She was also known as the princess of Corinth and daughter of King Creon.
In Greek mythology, Creusa (/kriˈuːsə/; Ancient Greek: Κρέουσα Kreousa "princess" ) or Glauce (/ˈɡlɔːsi/; Γλαυκή "blue-gray"), Latin Glauca, was a princess of Corinth as the daughter of King Creon.
In favor of Creusa, Jason abandoned Medea. In the version of the myth commonly followed by ancient tragedians, Medea obtained her revenge by giving Creusa a dress that had been cursed by the sorceress. The curse caused the dress, or Shirt of Flame to stick to Creusa's body and burn her to death as soon as she put it on.
