Meaning
possessing goodness (Italian form of Darius)
The story
Dario is the Italian form of Darius, which came through Latin and Greek from an Old Persian name combining "possess" and "good." Darius the Great, the Persian ruler whose forces were defeated at Marathon, gives the name an older historical bearer. Its old meaning, "possessing goodness," acquires an irreverent companion in the writer Dario Fo. When he received the 1997 Nobel Prize in Literature, the citation celebrated his kinship with medieval jesters, challenging authority and defending people pushed to the margins. At his Nobel lecture, Fo showed drawings he had made himself; smaller copies had been handed to his listeners. He explained that illustrating a speech instead of writing it out let him improvise, drawing on his own imagination and the audience’s. A literary honor had brought him to the lectern, but the listeners had pictures in their hands. The words still had room to happen between them.
