This chapter considers in detail two dialogues from the "Appendix Platonica": the short dialogue "On Virtue" and the "Sisyphus". Both build upon Plato’s "Meno", but with notable reformulations and, at least since the end of the nineteenth century, this play of allusions has been interpreted as a sign of forgery, even if confirming the Academic origins of dubia and spuria. By inquiring into the practical and exegetical background of these reprises, the chapter shows how production of school dialogues supported specific interpretations of Plato’s texts and could be used as a way to dialogue with the founder of the school through his writings.
