Pure brilliance, this book, pure brilliance.
Jo Walton may be the first author I've read that has done actual research on the era and person of interest in her book: Renaissance Italy, mostly Florence, and Girolamo Savonarola the Dominic monk known for his prophetic visions and for starting a bonfire of the vanities. In this book, Savonarola goes through a Groundhog Day situation; his lives a variety of different lives trying to change the course of both his own history and of those around him and each time he dies he starts over again, mostly in April 1492 near the end of the Christian observance of the Lent (hence the title) and the beginning of Easter. Walton incorporates other historical figures into the book whom Savonarola knew personally and communicated with, mostly Giovanni Pico della Mirandola. She shows how many Christian theologians, such as Savonarola and Mirandola, incorporated Renaissance humanism into their theologies which was something that actually happened during that time. As one other reviewer said, humanism in its infancy wasn't anti-Christian at all, heck, it was started by Petrarch who was inspired by the works of Saint Augustine of Hippo. It just placed humans at the center of the world's important questions and how they should respond to them; theological anthropology has its infancy here too, but that's another review.
Walton paints Savonarola as a multi-faceted man. He is not the mad monk many other writers and historians paint him as, though he is full of faults. He is not the holiest of men, something he knows and does not deny and something he consistently tries to work on. One the overarching themes of the book, and Savonarola's character arc and journey, is that of pride. Savonarola himself and so many other characters think they can control things, especially their own destinies even when they acknowledge God as the one who controls the universe. Let's just say that as a Catholic, this hit home with me. There was a lot I found relatable in Savonarola's struggles, doubts, and beliefs.
But what really takes the cake, what I really loved about this novel, is that is shows the fear of losing or being abandoned by God. This is not some Nietzschean proclamation about the "death of God" or culture's loss of focus on God. It shows the actual grief, fear, heartbreak, and emptiness one feels when one losses God, that you feel no longer loved or worthy. Again, a relatable thing for me. However, it also shows the pain of losing your friends, even if those friends have differences with you. Another theme I loved in this book is the constant reminder (I'm paraphrasing) that Earthly beauty prepares one for Heaven for Heaven's beauty cannot be matched.
Ultimately, this is a story of Heaven, Hell, Earth, devotion, friendship, faith, and hope. This may be one of my favorite novels of all time.
