Isabella, Three Sailing Ships and a Con Man (Italian title: " Isabella, tre caravelle e un cacciaballe") is a 1963 two-act play by Italian playwright Dario Fo, the recipient of the 1997 Nobel Prize in Literature.

Raja Rao (8 November 1908 – 8 July 2006) was an Indian writer of English-language novels and short stories, whose works are deeply rooted in Metaphysics.

 For the entire body of his work, Rao was awarded the Neustadt International Prize for Literature in 1988.

 In his time he was "arguably the most widely performed contemporary playwright in world theatre".
 Much of his dramatic work depends on improvisation and comprises the recovery of "illegitimate" forms of theatre, such as those performed by "giullari" (medieval strolling players) and, more famously, the ancient Italian style of "commedia dell'arte".
Jacopo Fo (born 31 March 1955) is an Italian writer-actor and director.
 He is the son of playwrights Franca Rame and Dario Fo.
