On 25 August 1657 Francisco Jacinto de Funes Villalpando y Ariño, Marquis of Osera, reached the city of Madrid after a long journey from Saragossa. It was not the first time the Aragonese gentleman set foot in the capital, but on this occasion he did so with the commitment of clearing his family’s name. His brother Don José de Villalpando, commander of the Lisbon infantry regiment, had been confined to the public prison of Barcelona since the beginning of the year, charged with having forced and promised to marry a young Catalan lady related to the aristocracy of the Principality. Osera took it upon himself to defend him and travelled to Madrid with the aim of reducing what looked set a priori to be a death sentence.

Determined to provide a detailed account of all his moves and of the result of his appeals to Philip IV and the negotiations with the royal favourite, grandees, aristocracy, ministers and secretaries, the marquis, a poet of middling talent and an amateur playwright, wrote a Diary in his own hand. Begun on the very day of his arrival, it ended hastily at the end of June 1659 when, on the day before the final judgement was issued sentencing Don José to four years’ exile in Oran, Osera had to return to Aragon to be sworn in as a deputy representing the high nobility.

The manuscript, which has remained practically unpublished until now in the archives of the Dukes of Alba, is revived in all its originality in this edition as its contents are fully published, including the parts of which we were hitherto unaware as they were originally ciphered.

Osera ended up making the Diary, devised as a means of communicating with his brother, not only an authoritative and insightful portrait of the court of the waning Planet King but also, inadvertently, a ‘mirror for gentlemen’, a metaphor of the representation of the aristocratic ethos in the Spanish Golden Age.

Santiago Martínez Hernández holds a doctorate in Modern History from the Universidad Complutense in Madrid, where he is full professor. His studies focus on court politics of the reigns of Philip II and Philip III, and he has published El marqués de Velada y la corte en los reinados de Felipe II y Felipe III (2004) and Governo, Politica e Representações do Poder no Portugal Habsburgo e nos seus Territórios Ultramarinos (1581-1640) (2011), among other studies, as well as twenty or so articles and chapters in books.

“Una aportación de verdadero relieve tanto para la historia cultural como para la historia política del XVII con páginas inolvidables que no desmerecen ante los Avisos de Pellicer o Barrionuevo”, Fernando Bouza, La Aventura de la Historia

“Hay ciertas ocasiones en que la producción editorial referente a la Historia Moderna nos sorprende con un libro atípico. Si, además, a su peculiaridad se une una calidad historiográfica indudable, […] el modernismo puede considerarse de enhorabuena. Y éste es el caso”, Fernando Negredo del Cerro, Tiempos Modernos

“Santiago Martínez nos regala esta espléndida edición crítica del Diario […], un inmejorable fresco de aquella corte de las novedades que fue el Madrid de los Austrias, con una mirada muy atenta a las aficiones y gustos del monarca, a la vida y entretenimientos de los nobles, a los juegos de poder y enredos palaciegos”, Antonio Castillo Gómez, Cuadernos de Historia Moderna

«El Diario es una fuente documental de primer orden para introducirnos en la práctica política de la España de los Austrias, un testimonio extraordinario […]. La edición crítica incluye un modélico estudio introductorio, un completísimo aparato crítico (casi mil notas) y un abundante y apropiado apartado de ilustraciones», MFG, Nobiltà
