A historical novel from one of my personal favorite Hungarian authors. Móra Ferenc (1879-1934) was a journalist, author, and a practicing archaeologist. All of those things merged together to create wonderful and fun pieces of literature (and also one of the most depressing children's book of all time, but we don't talk about that one - of course that is the only one we have to read in school...). Móra had great empathy and a very sarcastic sense of humor. Which are both good for writing about history.
In this novel, set in the times of the Roman emperor Diocletian, he mostly applies the empathy. The backdrop of the tale is a very turbulent era in the history of the late Roman empire, and the last great and bloody persecution of Christians. The hero is a young man named Quintipor with a mystery in his past, surrounded by many actual historical figures, both from the royal family and from their court.
The essence of the book is a love story, but even more important than that, the book (in my opinion at least) has a soul: The character of Titanilla, daughter of the Caesar Galerius. Móra allegedly modeled her after a love from his own life, but real person or not, Little Tit (no English pun intended) is a masterpiece of a novel character for the ages. Her cheerful, wild, decadent and yet kind-hearted being is set in contrast with Quintipor's naively good mentality, and an unlike romance blooms between the two, despite the difference in their social standing. Into this mix the author adds the theme of new-found Christianity, and the result is poetic, heartbreaking, and unforgettable.
If you can find the English version, read it. Some are available online, last time I checked, and some libraries in the US also carry them.
