I've spent the past couple of days dipping in and out of Richard B. Hilary's 1969 doctoral thesis on the appointments of Pope Pius II (1458-64). Aside from the nepotistic appointments, Hilary also included a helpful chronology of all the literary works that can be ascribed to Pius thus far. The pontiff covers a number of different themes in his works, which in part reflected his travels and his career, there's even a cheeky erotic novella (De Duobus Amantibus). As these works are of such scope, further discussion will follow.
'Because you have been many times in love, nor yet lack fire, you wish me to weave for you the story of two lovers... You will not hear the loves of Troy or Babylon, but of our own city, though, of the lovers, one was born under a northern sky'.
(De Duobus Amantibus).
