This work presents a critical analysis by Daniel de Priezac and Salomon de Priezac (not referenced in this copy) of the contents of a book by Jean Caramuel Lobkowitz (1606–1682).

In this study, the aforementioned Benedictine monk, who belonged to the Cistercian Order, held a doctorate in theology, and was one of the most emblematic authors of the seventeenth century, reflects on the right to the Portuguese throne of Philip II of Spain (1527–98), the son of Charles V and Isabella of Portugal, daughter of King Manuel I of Portugal. After the death of Cardinal Henry (1512–1580), the 17th King of Portugal, and in the absence of any heirs or direct successors, Phillip II of Spain became King of Portugal (Phillip I), which lost its independence and would not regain it until 1640.

This volume is covered by a characteristic binding from the workshop of Pierre Rocolet, who was also responsible for publishing the book in 1641. Made from red morocco, it uses frames consisting of lace-trimmed roulettes inside of which a delicate composition of small gilt stamps unfolds around a central cartouche bearing the coat of arms of Louis XIV. The compartments in the four corners, which are inlaid with olive-green morocco leather, feature a profusion of fleurs-de-lis which also appear on the outer edges, emphasizing the royal provenance of this binding.
