Baltasar and Blimunda by José Saramago

YET CONTENTED FAMILIES are still to be found. The Royal Family of Spain is one of them. That of Portugal is another. The offspring of the one marry the offspring of the other, from the Spanish dynasty comes Mariana Vitória, from that of Portugal, Maria Bárbara, their bridegrooms José from Portugal and Fernando from Spain respectively, as one would say. These unions are the fruit of careful planning, and negotiations have been under way since the year seventeen hundred and twenty-five.

Innumerable discussions have taken place, there has been much shuttling of ambassadors, much haggling, much coming and going of plenipotentiaries, many arguments about the various clauses in the wedding contracts, about their respective prerogatives and the dowries of the Princesses, for these royal marriages cannot be entered into lightly or quickly settled at the butcher's shop, as the lower orders quip when referring to some illicit affair, only now after almost five years of protracted negotiations has an agreement been reached about a formal exchange of Princesses, one for you and one for me.
