The Ad usum Delphini editions were 17th century monolingual paraphrases with L2 helps. The Latin ones are widely used and available, but according to the Wikipedia page

there were at least two Greek editions, for Homer and Aristophanes. After much googling I could not find these or any reference to these. Does anyone know where they might be found?
The inclusion of Racine seems to be a mistake.
