It was definitely hard going. I had multiple browser tabs open, the heavily annotated modern library version, and my years of Catholic upbringing to guide me through it all and it was definitely a journey. I read it right after reading Dante’s divine comedy and while the comedy and they both really blew me away. Half of Paradise Lost (and Dante too for that matter) is just really deep references to the Aeneid, the Iliad, the odyssey, and Ovid’s metamorphoses.
