Arria

In Roman mythology, Arria was a woman whose husband, Caecina Paetus, was ordered by the emperor to commit suicide. He wasn't capable of forcing himself to do so until Arria grabbed the dagger from him, stabbed herself and then gave it back, informing him that it didn't hurt ("Non dolet, Paete!").
