O thesouro do rei Fernando historia anecdotica de um tratado inedito

A vivid slice of late‑medieval politics opens the work, where a diligent researcher in Angers uncovers a little‑known royal charter dated 1377. The document records a pact between Portugal’s King Fernando I and the Duke of Anjou, outlining a joint campaign against the Aragonese monarch. By reproducing the original text and the surrounding diplomatic formalities, the author invites listeners into the very moment the treaty was sealed amid a gathering of nobles, clerics and royal officials.

The narration weaves the transcribed charter with lively commentary that paints the ambitions, rivalries and personal dramas of the Iberian courts. Readers hear the clash of Portuguese resolve with French dynastic interests, and glimpse the broader Mediterranean contest that shaped the era. The book remains anchored in the first act of the story, offering a richly detailed portrait of a forgotten treaty without spilling the later outcomes of the conflict.
