Horst Schroeder: "Some Historical and Literary References in Oscar Wilde's 'The Birthday of the Infanta'"

A quick, interesting piece of research, "Some Historical..." proposes that the Infanta's father is actually meant to be Charles II of Spain. Schroeder builds his argument on some convincing circumstantial evidence- people of the times, similar names or traits, coinciding events. He does have several articles of evidence along these lines, which makes an overall believable argument. I don't know how useful this will be for my purposes, but I'm glad I read it.
