Welcome to the world of 18th century Portugal! This world of ancient Portugal involves the plague, classes split down the middle, the Spanish Inquisition, lots of wealth held only by the 1 percent, and lots of supernatural power. It is full of lots of priests and religious people, some of whom are mentally ill. Specifically, this story is about a soldier and a psychic and a priest as well as their adventures.
The three main characters in the book are Baltazar, Bilmunda, and Bartholomew Lourenco De Gusmeo. Baltazar is a soldier who has just returned from war and is happy to be home. Unfortunately, Baltazar has been permanently maimed in the battle. His girlfriend and lover is Bilmunda. Bilmunda is a clairvoyant psychic you can actually see inside people's minds and bodies. The final character is a priest who is not quite right in the mind, but is very interested in inventing things. At this point he wants to invent a flying machine and enlist the help of the other two characters. It turns out that the priest's flying machine does fly, but it has disastrous results every time it gets off the ground. There are many adventures here having to do with both the flying machine, the Inquisition, the two strangely mismatched lovers in the title, the materialism of the wealthy, and the harmful effects of the plague.
In conclusion, it is important to note that the author wrote this historical novel to prove something:
The world is a comedy to those that think, the world is a tragedy to those that feel.
